UNSW researchers convert sunlight to electricity with over 40 percent efficiency
www.eurekalert....
“UNSW Australia's solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported. The record efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the United States.”
DARPA pushes for 50% efficient photovoltaics to power soldiers' small tools
spie.org/x8772.xml
“Photovoltaic solar cells already provide the armed forces with portable power supplies. But with their present low efficiency, a 60W laptop recharger would require more than 0.37m2 of solar cells.”

You didn't even remotely address the question you raised in the title of the video! While informative, very misleading, and very disappointing. I would like to see a video actually dedicated to this question.
the problem is that efficiency is not everything, if its more expensive, harder to maintain and less durable than conventional energy sources, no one will be interested. it already takes so long to pay for itself, and by then the solar panel will be at the end of its life... so as soon as you are done paying for it, you already need to replace the old one
+Peter Jörgenson (LemonBird) Everything is about economics, dipshit. If it costs a fortune to produce solar energy, then that means it is CONSUMING vast amount of resources in its production. And chances are that the manufacturing processes involved utilize large sums of fossil fuels and hazardous chemicals. D'oh!
*Solar energy* kill poeople!
Never answered the question
+phxtonash The answer is no.
+TheRealNaxos That seems obvious. There are a lot of industrial systems that need to run 100% at peak, like sewage treatment and nuclear plant regulators. Solar can power 1/3rd of the world, once scaled up, which is good enough for me.
+phxtonash The answer is yes, but not yet. We'll need better energy storage systems to do that.
Right but heterogeneous green energy grids will be ready before that, so solar will never NEED to run the world itself.
+phxtonash Solar could actually power the entire world's needs right now, and the total amount of solar panels needed to do so would take about the amount of space as Nevada. Some people balk at that size, like "The size of Nevada! That's completely unfeasible!" when in reality if one in three households had solar panels, we'd be good to go.
I have a question: I live in Southern California where we are very much encouraged to recycle, but I've read that you are supposed to thoroughly rinse plastics before putting them in the recycling. But we are in a horrible drought. So is it better to use water and rinse everything out, not recycle, or just throw it in the bin dirty?
Thanks for updating us on the cutting edge of photovoltaics.
20.1% efficiency in lab is very different from 20% in mass production.
I kind of feel guilty now for watching this at night with the lights on and fan running. lol
you could probably replace your home lighting with LEDs on a closed DC system connected to a battery (charged by solar panels) for just a couple hundred dollars (you loose allot of efficiency in AC LED lightbulbs by converting the high voltage AC to low voltage DC so you might aswell just use a DC system for both simplicity and efficiency)
What you mean you always thought that we would be flying you’re like 25
I like the way you say "Only improved from 1% efficiency to 20%" like it's barely worth mentioning... that's a 2000% (20x) improvement!!
First, get a non-conductive material, put a layer of conductive material on top of it. Then, make the conductor as black as possible; minimize on reflected light. The blacker, the better. Cover it up with something transparent, fill it with water, and place a conduit, pipe, or straw in the container to allow the water to flow in whatever direction you desire. Perhaps place heavy particles in there, such as lead, bismuth, or tungsten, so that the device can retain more kinetic energy.
Not much of a solar panel, but it's hot.
I have a question for you guys. I saw a commercial that bemoaned ethanol for converting grasslands into corn fields, claiming that this would lead to an increase in greenhouse gasses. Now my impression was, both are types of plants, so they should convert the same amount of CO2, and while there is some CO2 cost in actually farming the land due to tractors, the fields themselves would be CO2 neutral compared to each other. So what are the facts? Is there a serious difference between an acre of grass and an acre of corn? How much CO2 would be spent harvesting the fields? What if the farm switched to green tractors? More research is needed!
The problem is...the most potent renevable energy source are in west of USA when the biggest energy demand is in the est - the place with tornados and hurricanes :\
Yes we can :D!
But generating power using fusion power and then having advanced batteries in cars.(unless you are Bethesda and put a fusion reactor on each car...)is so much better :D!
I have never heard of this Bethesda car company. They sound really innovative! I bet they could make people/dragon hybrids too. We'd call them the Dragonborn.
Solemn Mojo Bethesda is the ones who take part in the creation of the game fallout. And in fallout 4 they said everyone had fusion powered cars :D!
+Jørgen Reinnes you didnt get the joke. He just said Dragonborn.
smh
Do a video on Cold Fusion! It's really interesting :)
If it were true.
+jordan larner They should do a video on the easter bunny too then
1. Nuclear Energy
2. Fossil fuels mixed with alternative energy when it's effective
3. Solar panels and other jokes
Solar energy might be a viable option closer to the equator, provided that you have batteries to store energy for the night, but here in canada, we get very little sunlight in winter, when our energy use is at it's highest, not to mention that the panels would get repeatedly covered by snow.
+Keven Harvey Localized solar generation wouldnt be necessary if cost and efficiency of solar energy were improved. Theres more than enough energy on the equator to power the entire planet many times over.
Daniel Dryden
Well I was responding to the title of the video, where it would be the only source of power, and that isn't feasable everywhere on earth, for now at least.
+Keven Harvey
solar panels become more efficient when its cold. even with less light the difference isnt all that big. (tho complete darkness would still be an issue)
yunthi
In winter we can get less than 9 hours of daylight and the angle of the sun is quite severe, the temperature can drop to -30°C at night (without windchill), so the amount of energy required for heating is enormous, I'm not saying solar panels are useless, but I can't see how it could possibly be used as the only source of energy.
Keven Harvey for sure, i live in finland which has pretty much the same conditions. my point wasnt about the impossibility of solar panels being used as a sole source, just that they actually work surprisingly well even up north, due to the increased efficiency in cold temperatures.
This is the rare case where a video that uses a question as a title should be answering with a simple "yes". In the long term, everything is already solar powered. It is just that the solar energy got stored by some natural system such as the creation of oil. We can do what the natural system did.
Silicone != silicon.
+Jon Proce Python Code?
+The Evaluator There are a lot of languages where != == ≠
+Penny Lane I like the fact, that you've put double =, probably without even noticing it.
+Oleksandr Mukhalov
"x == y " means is x the same as y
"x = y"means make y The same as x
So
x = 1 :x is 1
y = 1 :y is 1
X == y :Is true
+Oscar Champion I know that. I meant that since he was probably explaining not only to programmers, but to everyone else too . It would seem quite strange for a non programmer.

Regarding flying cars, we do have them. They're just not designed to look like cars because we would need unthinkable amounts of power and noise to run them. These flying cars, often called "Helicopters" are used by thousands of people every day.
The problem with them, however, is that they are expensive, consume more fuel than regular cars, CANNOT BE MADE TO OPERATE OFF BATTERY POWER FOR EXTENDED PERIODS and in general are excessively loud. They are also moderately dangerous and parking them is a serious problem.
The thing is, for some very good reasons, the helicopter has not had a "Model T." There has been no industrial-scale production of cheap helicopters for the working class, and there is no infrastructure to support helicopter commute by the masses. It's also not exactly green to be burning gas or jet fuel or even methane in your chopper commute, and would further exacerbate noise pollution.
Not to mention idiots would run these giant tanks of fuel and whirling blades into cliff-sides and buildings.
Storage is the real problem. 90% efficient panels won't change the world unless we have viable storage methods. You guys should do a video on smart grids or storage advances.
Not without peaker plant or massive battery backup system.
its all well and good but how many panels on my roof i would need to heat just one kettle???
can you anser this qwestion mabey, are solerpannels stil juse bol avter 25 year ? (stil aver that the need to be recykelt as wel .... )
And, again, an episode that has little to do with the title. Not that "Can We Power Everything With Solar Panels?" is a very good question. "Can we switch to 100% renewables?" would be the much more realistic and much more relevant question. And then "What are the costs of switching and what are the costs of not switching?" as a follow-up.
In my country, Yemen, the national power grid shut down about 10 months ago, with the absence of fossil fuel, we were forced to turn to solar energy for electrisity. Now that most homes and fasilities are running on solar, we realize how dumb we were ignoring it all along.
How long would a solar panel last and at what rate would the efficiency decay?
How do you get the DC output of Solar panels boosted to 500KV AC for transmission over long distances?
I have a question about rainbows. I understand that rainbow is formed by twice TIR inside a water drop but why the band of rainbow formed in the sky is always curved somewhat elliptical or parabolic why not any other shape.
Unless solar panels become dirt cheap, I can't see them over taking conventional forms of energy(fossil,nuclear etc).
+Adam Lawrence Solar has been plummeting in price, not to mention if it received the same subsidies that fossil fuels received, they would be far cheaper.
Well go into a little rum and burn some fossil fuel and see how long you would/could stay in that room
Thats what happening with earth but you cant just leave earth like you can that room
+Adam Lawrence Solar panels have been making massive gains in the price and efficiency department and they really do look like they could turn the tables on fossil fuel in our lifetime if progress keeps its pace. Once its efficient enough then companies will start to want offering said successful product out to the public in higher demand which means more production and when there is more production the processes used to produce improve and you get a cheaper product that is still just as efficient.
+Adam Lawrence
im thinkin solar power could make a bigger difference in personal level. i mean there are stuff like paints that can capture some solar power, window coatings that use the ultraviolet and infrared to transform that into energy (leaving the visible spectrum untouched). also personal windmills that you could mount on your rooftop, that look like a ball instead of the traditional bladed model.
stuff like that. stuff everyone can use while building a house.
im not sure about other countries, but in finland the electric company is obligated to buy any excess electricity a house produces, so in theory you could sell some of it back to reduce the cost of your electric bill during the times you dont get either sunlight or wind.
or it could be used to power your electric car for instance.
even today, if you do something like this, you are able to save some money. the equipment will pay itself back in the long run, altho the original investment is somewhat costly and it does require some maintenance.
+Adam. Get this friend: If the were free----lets say someone paid you to take them---they still can NEVER compete successfully except in small specialized situations. What you say is buttressed by authors like Robt. Bryce to a T.
Flying cars have been invented, just not mass produced
Joe Khaled
Prototypes
yes you are the clever
the way people drive..I hope they never come about
MORE INFO FOR THOSE INTERESTEDPerovskites are awesome BUT of serious concern is how stable they are in air: metal-organic hybrids tend not to do so well in the presence of oxygen and water. This is where there is also a lot of research at the moment: cheap and sturdy methods of keeping oxygen and water out.Additionally there's some cool research going into what are known as Quantum Dot Solar Cells. Also cheap to produce, more stable I air and have the potential to break what's known as the Shockley-Queisser Limit", which caps Silicon solar panels (or any panel mad with only one active material) at 33%. Not so with Quantum Dots, but at the moment they're hovering around 10% efficiency which isn't very good yet.
The fact that no one responsible for this video was scientifically literate enough to stop this chick from calling silicon "silicone" is telling. Great work Discovery.
I got this sweet solar flash light from Lowe's a couple years ago with battery back up
There's also thermal depolymerozation. Make a video on that please
if u use solar to power a low voltage motor to turn a generator like water wheel generator u can power who building free 24/7 power so yes u can the generators can even power u drills welding ect... too
Im surprised you guys didnt notice or mention the thirteen year old Aidan Dwyer who made extremely efficient solar panels using the Fibonacci Sequence. His model provides a 20-50% boost over the normal uniform solar panels.
Why are they low on electricity in Tanzania? Is the economy not sufficient to provide that cash? Knowledge is everywhere and people can go to universities worldwide. Is the government unable to organize necessary infrastructures?
does DNews HQ have any solar panels on the roof?
0:04 People who keep track of tech did not expect that.
The failure and pending closure of Ivanpah should warn us to slow down.
Also this isn't the first design to have promise, manufacture-ability has held down good designs in the past.
Should talk about the fact the electric car was created before the combustion car engine, but was blocked by fuel lobbyist who would lose out on profits from less sales on oil.
It would 400 x 400 km of solar panels in Africa for all 15 tw per hour.
Or 200 x 200 if efficiency max.
World energy consumption (ca.)
80 % - Coal, gas and oil
10% - Renewable
10% - Nuclear
Coal, oil and gas: Bad for the environment.
Renewable: Good for the environment, but can not meet energy demand.
Nuclear: Co2 neutral, can meet world energy demand. (But has a bad reputation)
We have been trying to make renewable energy effective enough for many years but not seeing adequate progress. Meanwhile were using "dirty" energy to meet 80% of our demand. How environmentally just is that? We need to take use of modern nuclear power before it is to late.
Google it people, it might just change your mind.
It certainly changed mine.
Solar is not the power of the future, unless we switch to using something like rectennas instead of the kind we use now. The kind we use now also requires materials that are produced with lots of toxic chemical byproducts. I would like to see an honest video about the negative environmental effects of wind and solar, since people don't seem to know about them.
+reviveempires I think that the idea was/is good, but the only real technologies to solve the problem have been continuously sidelined, probably because there's so much money to be made in "green" energy. What do you think would be an effective way to counter the "Renewable Energy" propaganda?
how are the going to be recykelt ? ore are we going to do the same thing again by not maken that a obligated thing for seling it.
When Australia developed the Sliver Cell Solar tech, instead of using it and selling it to the world to help Australia, as usual Australian tech sold the rights overseas so someone else could develop it, because Australian companies don't like to take risk! We are the sit back, let someone else make it work then we'll buy it rather than invest in developing usable tech.
If that isn't bad enough, in a country with one of the most sunny days in the world, the Australian government still refuses to help the solar industry to develop, but more over won't support the populace from using it. As a result, domestic use of solar tech in Australia is miniscule.
You had one job and that was to answer the question.
@Dnews Were automatic watch type mechanisms ever an option for generating electricity, for example, in portable electronics other than watches?
Good news however the video titles question remains unanswered and hence needs to be considered a click bait. DNews you are on my proceed with caution list now...
What's that background wind noise in Every Single Of Dnews's videos ?
There are flying cars, they're just not affordable and there aren't lots of them.
can solar power, that uses the photons from the sun, and then is used to power homes, cars, and offices, be used in such a manor that reduces the amount of sun rays that heats the planet's surface? I am obviously no expert, but it seems like it could help along with using less pollution type power sources.
Until solar panels reach 80% efficiency and cost less than grand to produce 63 kWh a day it'll still be a difficult sell, due to the fact that to be independent of the grid cost about the same as a car. With higher maintenance cost...
Hey what about solar thermal? you didnt discuss it!!
so how expensive were those 42.8% efficient solar panels?
+cubedude76 Those panels are so expensive, they are only economically viable in situations where weight is a bigger factor than cost, mainly space travel.
what is the point of naming the video as a question and not trying to answer it? click bait?
Everything could eventually be powered by solar panels but it wouldn't be smart because solar energy eventually dissipates as heat into the atmosphere. Photosynthetic trees and plants are a more effective cooling system because they absorb and store sunlight, which prevents it from heating up the ground under it in the first place. The stored energy is then released in fall and spring when fallen leaves compost.
Solar energy can be used for everything, but everything currently running on electrical power is already too much. Even if CO2 levels can be reversed to blanket less heat, additional heat in the atmosphere from any source dries the air and prevents it from condensing and precipitating. For adequate rainfall, reforestation combined with reduced energy consumption is needed to cool down hot areas and revitalize the water cycle.
Solar and wind is now powering at increasing rates our houses, our vehicles, our industries. New wind is 2.5 cents and new US solar is 5 cents a kilowatt hour. Plug in our vehicles and save $1,500 a year by eliminating buying tanks of gasoline. Max out building insulation and then install roof top solar. I recommend SunPower with highest efficiency and cradle to cradle certified materials for clean disassembly and remanufacturing.
Can you do a video on why we all have different hand writings? And why we don't like our own?
FYI - silicone and silicon are very different things. Solar panels don't contain silicone.
well damn it I didn't know the multi bandwidth thing was being done so much for patening that one.
The efficiency of a solar panel does not make one bit of difference. The fuel is free. It is the cost per watt which is the most important number. Get that down, and you will see more solar panels, regardless of their efficiency.
question for you why need cars to have computers engine management and other stuff in the old days it just have a carburetor
Can you go over IGA deficiency?
DO one about advances in nuclear energy. I think both solar and nuclear will be the norm for the future of eletricity.
Strange that wind is growing faster than both solar and nuclear, they won't be the norm anytime soon.
She did not answer, however the answer is most likely yes, to bridge it to full yes we need batteries. It's on it's way, and only thing stopping the acceleration is OPEC and people spreading old and long disproven BS
_Want innovation to take place, start it. Oil companies are billion dollar industries that control which cars and fuels we use._
You need to talk about the fact they only work 6 or 7 hours a day.
if pervoskite-based cells are half the cost of silicon (not silicone!!) it would make them significantly cheaper than fossil fuels... silicon is already roughly at the cost/watt level of traditional carbon power
The smart move now is to switch to thorium molten salt reactors for a stable power source while building up solar, wind, and hydro sources. Too bad ignorance, fear, and bottom lines keep us burning coal.
Can you do a video on why some people have certain preferences in what they look for in the opposite sex? ex. I have a weak spot for red heads
I can't wait to pick up a box of Nabisco's New Silicone Wafer Sandwiches! mmmmmmm :P
yeah I have a sample my car battery protector is a solar panel always starts on cold days
My favorite solar powered device are the orange trees in my backyard.
Favorite solar powered item would be those really old calculators that don't have batteries
whatever happened to those Thorium Reactors? why arent those a thing?
China, India, US, Russia and EU are developing them ( especialy China/India) while the rest focus more in Fusion
Can we power everything with solar power? Yes, we just need more solar panels.
Her LHOTP dress resembles the solar panels. Were solar PV cells around in the 1880's?
Dnews please make a video about "What is Low Latent Inhibition?"
There is only one thing that powers me, not food, not water, it's you Julia, yes you sunshine :)
..get it...cause of solar power....oh well back to the drawing board :p
Solar powered flashlights. we need those Asap
So you the developers figured out a different path to make the molecule? 2:46 to:2:56.
? More. plus channel maybe?
what about thorium reactor you guys should talk about this please thank you :)
!!Pedantic Grammar Alert!!
Silicone is for plastic surgery.
Silicon is for electronics.
Hopefully the prices keep droping
can I power my home by farting?
More efficient solar panels are great, but according to Elon Musk, they are no longer the most significant factor retarding large scale adoption of solar power. The cost of installation and even more, the cost of storage technology are now more pivotal. Significant strides are being made in those other areas as well of course. It is already the case that solar power is cheaper than conventional power sources in some areas for some uses. The costs of solar systems will continue to decline, while the costs of fossil fuels will very likely continue to rise. It is an inevitably that at some point, very much within the lifetimes of most reading this, that solar will be sufficiently cheaper than fossil fuels, that nobody in their right mind will burn it for power.
At the start of the video, Julia looks really tired with bags under her eyes, but then they suddenly disappear.
Solar panels aren't expensive. Generating electricity is cheap. Storing it is where we run into problems.
You run into a cost and efficiency problem when attempting to transmit it across vast distances
Pop's Shack check out www.BequestTech.com
Battery Storage Game Changer has arrived.
what about Graphene solar cells
Simple answer, yes, we can and will power everything with solar and wind, one day. I work in the utility renewable energy industry and know that solar and wind are capturing virtually every new utility new capacity contract, with nat. gas acting as peaker and back-up plants. Neither coal nor nuclear win any new contracts, they're dead technologies.
Why not just Nuclear? It is safer than conventional power, far more efficient and cheaper than solar panels, and basically the most green option of any power source.
TheAwesomeGamersDK1 I never said renewable, but if you go by that nothing is really renewable. The Sun might have a very long life span but its technology needs to improve greatly to make solar power the only source of energy. Plus the techniques for extracting materials and building them need to be far better. And I will not say that is it impossible but if you want to focus short term (the next hundred years minimum) I think that nuclear power is reasonable.
+TheAwesomeGamersDK1 Heard of Thorium and Nuclear Fusion?
Thanks for the really useful information, but you didn't answer the question. When you ask if any renewable could power everything, you should be talking about power grid stability. Something like this: www.pri.org/stories/2015-04-07/when-grid-says-no-wind-and-solar-power-companys-technology-helps-it-say-yes-again Basically, you need large battery-power plants to make a power grid stable.
these video titles have become more and more misdirecting, the question asked in the title was neither answered nor even mentioned in the episode.
and this seems to happen more and more often lately
The game Boktai is my favorite solar powered device.
Talk about concentrated solar power towers!
But u still rely on battery to store and maintenance , to me solar panel isn't that worth when it comes to cost cut down
Soooooooo was that a "yes" or a "no"?
so can we power everything?
u missed on that 😧
