Like many break through technology it will take many years before it's commercially available. It will either be available after few years or it will quietly disappear.

@@GreatDataVideos The reason I was wondering about power generation efficiency is that weight is not always a major consideration.

Any time a report omits a common measure of performance (and substitutes another measure), you can be sure the device does not perform well in the common measure. You *should* be very curious that the Watts/m² performance is not mentioned - that likely means it is not good compared to standard silicone cells. Now it's Watts/kg performance IS interesting, but probably doesn't hold as well when the cells/panels are integrated into some structure robust enough to keep them from blowing away or being torn up in the wind. Also not mentioned in the video is their stability against degradation in the environment, often a downside in organic PV cells.
@@SansNeural Hey. Caution is fine, but did you listen to the vid? They're working on a protective film. This is research. The commercial viability will come later.
@@veramae4098 "working on" is cold fusion slogan. Piece of foil will degrade by stuff like ozone. If they will develop polymer film - it will be "forever plastic" problem. They will have to use glass to stop ozone and uv and to keep it environmentally safe.
100 times lighter works if you can stack these in the same space as regular commercial panels. Since you can’t, then it takes up too much area because of the low efficiency. If you have competitive efficiency then its probably in a lab, like the material degrades easily in ambient conditions. If you compare to commercial panels, don’t omit the other stuff.
What about the extreme temperature? Can it withstand both freezing cold and boiling hot weather? What about the protective material's extreme weather handling capabilities?
PV coated shipping containers could power their own transportation. In Canada, the max train length is 16500 feet, if the train is entirely made of wellcars arranged in three-packs at 204 feet each, (each with a combined 1500 square feet of useful surface area) it will have 81 of them = 11300 square meters at 200watts per m^2 = 2250kw. A locomotive eats 3000kw. The locomotive is a lot heavier than the freight it carries and so ditching it would mean a effeciency gain. The reason it's heavy is for traction, which you don't need as much when your power is distributed over 3 miles of track. Then again, this is the umpteenth version of the "printable" photovoltaic. Nonetheless, good job! I like the fancy logo printed on your lab supplies/mastics. Very good use of money. :P
“It generates 730 watts of power per kilogram when freestanding - A typical rooftop solar installation in Massachusetts is about 8,000 watts. To generate that same amount of power, these fabric photovoltaics would only add 20 kilograms to the roof of a house,” he says.
@@interesting2709 But 20kg of this material will most probably take up a lot more space than traditional heavy solar panels. This is why I ask. The new technique may save weight, but it needs a lot more space because the power per surface area is lower. In other words: this cannot replace traditional solar panels on a roof. Imagine the roof that needs 1000 pounds of traditional panels only needs 50 pounds of the new ones. The roof surface area is 100 square meters, but how much does 100sq meter of the new panels actually weigh? I bet it weighs less than 50 pounds, so if the output per sq meter is lower, there's no use in replacing the traditional panels since you can NEVER have enough power output with the same surface area. The weight is irrelevant in that use case as it doesn't contribute to the comparison when looking at actual practical power output.
So which thin-film solar cell is it? Is the material as readily available? Non-toxic? Is the cell durable in the long term (e.g. Perovskite cells can be good but degrades due to sunlight).
Gads. This is research. They're working on a protective film. They're not claiming commercial viability. After the Wright Brothers first flight a newspaper asked an American general if there'd ever be any useful military application. "No," he confidently replied.
What about power generation per surface area rather than per kilogram? Because many applications can be named where surface area is a much more valuable asset compared to weight.
Yeah this tech seems the most relevant for applications up in space, where weight is the primary concern & there's no worry about air degrading the delicate nanomaterials. Up there the solar "panels" can be deployed as big as they need, there's always more space available.

There way too much hype floating around about solar panels these days, but if there's anybody I trust to just get shit done without needless hype, it's MIT. Keep it up, you guys, this tech will be revolutionary if it can make it to mass production and be durable enough to be cost-effective in the long run.
It is actually already to being (relative speaking) mass produced by Heliatek in Dresden.. I just don't figure how MIT managed to claim this their innovation just now 🤔
If this is the case than we can use this foldable and flexible solar panel in automobile to spread it when want to charge and squeeze it when not in use. Like a dust cover for cars.
I cannot retrieve a video where an american indian teenager from the MIT invented a thin, flexible infrared cell able to produce electricity 24/24. It was planned to be in production very soon. And it was around 4 years ago. If you have links I'll be very grateful to have news about this girl and her invention.
Can someone start commercial application asap please. This seems like it could be the new perfect residential solar roof. If you adhere this to the middle portion of a standing seem metal roof, then have the power leads at the top under the ride vent out would be so easy to install. 90% roof coverage, easy and cheap on most houses, and you would even see wires. I bet you could even design it so the bottom end could be cut to size with minimal treatment.
Just imagine tattoos with this new cells, generating power and feeding the person with energy there by reducing food requirements. I wear it and do Mountaineering or anything and dont get tired.
Just need to adress, longetivity, durability against enviromental surges, and toxicity when disposed. While I firmly belive it will be still used if all that goes down hill, it would prevent mass production and would only be avaiable in custom stuff.
So, there's a chance we may be able to get super creative with how these cells look as well. Print the nano cells in one pattern and then screen print the solar cell on top of that in another pattern over it.
The formatting of this video and it’s description seems to imply that this is technology invented by MIT but that is simply not the case? Slot die printing of solar cells has been around for years now and is certainly not something one can attribute as a recent breakthrough from MIT. Perhaps the description could be altered and clarify that this is not an MIT invention but rather just continued development of what has already existed for years, as severe people in the comments seem to be confused. Awesome work though!
One might use these to make artificial leaves and then artificial plants that then can generate electricity but look like plants. This could have both commercial and military applications. BTW, I just made a video and uploaded it my RUclips channel that describes the latter.
If anyone wants to learn a little more about the fabrication method used here, it is called slot-die coating. It's pretty cool stuff!

Perovskite solar cells are commercially available in Poland, check Sauletech
Near future possible monitoring health on medical devices work on it. Great idea
Hmmm. That could scale. Solar sailboat would be awesome.
That's an awesome contribution. Thanks!
I'd be curious to know how much power they generate per surface unit
Any time a report omits a common measure of performance (and substitutes another measure), you can be sure the device does not perform well in the common measure. You *should* be very curious that the Watts/m² performance is not mentioned - that likely means it is not good compared to standard silicone cells. Now it's Watts/kg performance IS interesting, but probably doesn't hold as well when the cells/panels are integrated into some structure robust enough to keep them from blowing away or being torn up in the wind.
Also not mentioned in the video is their stability against degradation in the environment, often a downside in organic PV cells.
370 watts per kilogram
1:33 that info, and more.
@@SansNeural Hey. Caution is fine, but did you listen to the vid? They're working on a protective film. This is research. The commercial viability will come later.
@@veramae4098 I know all that, but I have to try to temper the gushing praise and expectations that others in here are running on about.
@@veramae4098 "working on" is cold fusion slogan.
Piece of foil will degrade by stuff like ozone. If they will develop polymer film - it will be "forever plastic" problem. They will have to use glass to stop ozone and uv and to keep it environmentally safe.
Very nice! See a lot of applications for this.
100 times lighter works if you can stack these in the same space as regular commercial panels. Since you can’t, then it takes up too much area because of the low efficiency. If you have competitive efficiency then its probably in a lab, like the material degrades easily in ambient conditions. If you compare to commercial panels, don’t omit the other stuff.
This is helpful if you cover these solar panels throughout your roof then you can power the entire neighbour hood
What about the extreme temperature? Can it withstand both freezing cold and boiling hot weather? What about the protective material's extreme weather handling capabilities?
a deployable solar awning for my Prius and/or anyone's RV would be awesome... wonder when will it hit the market
PV coated shipping containers could power their own transportation. In Canada, the max train length is 16500 feet, if the train is entirely made of wellcars arranged in three-packs at 204 feet each, (each with a combined 1500 square feet of useful surface area) it will have 81 of them = 11300 square meters at 200watts per m^2 = 2250kw. A locomotive eats 3000kw.
The locomotive is a lot heavier than the freight it carries and so ditching it would mean a effeciency gain. The reason it's heavy is for traction, which you don't need as much when your power is distributed over 3 miles of track.
Then again, this is the umpteenth version of the "printable" photovoltaic. Nonetheless, good job! I like the fancy logo printed on your lab supplies/mastics. Very good use of money. :P
Progress is being made - and inventions like this will truly "save the world." Thanks for posting!
Cool. So exited to never hear about them again .
Imagine this as a phone case
But what is the power ratio when looking at the surface area? The power increase per weight doesn't say that much to me :)
It's nascent and it cannot be mass produced for the time being. I cannot see why these constraints would even let it get higher power to weight ratio
“It generates 730 watts of power per kilogram when freestanding - A typical rooftop solar installation in Massachusetts is about 8,000 watts. To generate that same amount of power, these fabric photovoltaics would only add 20 kilograms to the roof of a house,” he says.
@@interesting2709 But 20kg of this material will most probably take up a lot more space than traditional heavy solar panels. This is why I ask. The new technique may save weight, but it needs a lot more space because the power per surface area is lower. In other words: this cannot replace traditional solar panels on a roof.
Imagine the roof that needs 1000 pounds of traditional panels only needs 50 pounds of the new ones. The roof surface area is 100 square meters, but how much does 100sq meter of the new panels actually weigh? I bet it weighs less than 50 pounds, so if the output per sq meter is lower, there's no use in replacing the traditional panels since you can NEVER have enough power output with the same surface area. The weight is irrelevant in that use case as it doesn't contribute to the comparison when looking at actual practical power output.
Now make the plastic bio based and you can count me in
So which thin-film solar cell is it? Is the material as readily available? Non-toxic? Is the cell durable in the long term (e.g. Perovskite cells can be good but degrades due to sunlight).
Gads. This is research. They're working on a protective film. They're not claiming commercial viability.
After the Wright Brothers first flight a newspaper asked an American general if there'd ever be any useful military application.
"No," he confidently replied.
What about power generation per surface area rather than per kilogram? Because many applications can be named where surface area is a much more valuable asset compared to weight.
Cost per power generation is also one of the most important factor
Yeah this tech seems the most relevant for applications up in space, where weight is the primary concern & there's no worry about air degrading the delicate nanomaterials.
Up there the solar "panels" can be deployed as big as they need, there's always more space available.
"The specific power of our integrated fabric-PV modules is 370 W kg−1, weighing 105 g m−2, while the free-standing devices had a specific power of 730 W kg−1, and weigh 52 g m−2."
From the paper, if someone wants to work out the Watts/m²
38.85 Watt per square meter for the integrated fabric-PV modules?
37.96 Watt per square meter for the free-standing?
Normal Solar Panels produce 150 Watt per square meter.
So this is for the light weight solution, when you care about weight. For stationary panels it's 4 time more efficient to use normal solar panels.
1:47 and how many football fields could you cover with that?
will this be cheap enough that poor people - middle class and below can afford it too? asking for a whole section of the population. ty
There way too much hype floating around about solar panels these days, but if there's anybody I trust to just get shit done without needless hype, it's MIT. Keep it up, you guys, this tech will be revolutionary if it can make it to mass production and be durable enough to be cost-effective in the long run.
It is actually already to being (relative speaking) mass produced by Heliatek in Dresden.. I just don't figure how MIT managed to claim this their innovation just now 🤔
Every building on earth must be covered with this solar skin
If this is the case than we can use this foldable and flexible solar panel in automobile to spread it when want to charge and squeeze it when not in use.
Like a dust cover for cars.
Incredible!
Amazing source of power
For Ito layer you deposited it
Paper-solar cell give hope to replace fossils as a source of energy for our daily usage .
That is amazing!
All EVs can have then intergrated to the roofs, hoods, trunks, doors basically every surface of that EV can now generate power
It's awesome 😊
I cannot retrieve a video where an american indian teenager from the MIT invented a thin, flexible infrared cell able to produce electricity 24/24.
It was planned to be in production very soon.
And it was around 4 years ago.
If you have links I'll be very grateful to have news about this girl and her invention.
What about maximum temperature
Can be damaging easier 2:45
Keep us updated please
Klingt gut, wann kann ich bestellen?
Can you get it a few thousand to us by Tuesday?
Can someone start commercial application asap please. This seems like it could be the new perfect residential solar roof. If you adhere this to the middle portion of a standing seem metal roof, then have the power leads at the top under the ride vent out would be so easy to install. 90% roof coverage, easy and cheap on most houses, and you would even see wires. I bet you could even design it so the bottom end could be cut to size with minimal treatment.
There always seem to be a catch with these new technology breakthroughs. I wonder what’s up with this one, as the video is not telling.
Which electrode is deposited on the structure to complete the solar module?????
This is crazy good
but no word on efficiency ?
Just imagine tattoos with this new cells, generating power and feeding the person with energy there by reducing food requirements. I wear it and do Mountaineering or anything and dont get tired.
Just need to adress, longetivity, durability against enviromental surges, and toxicity when disposed. While I firmly belive it will be still used if all that goes down hill, it would prevent mass production and would only be avaiable in custom stuff.
so many "could"s in this video... someone's trying to get funding lol
I'm gonna sticker my porsche with this and fly to mars without fuel stop. Who the . is Elon?!
Thank you for share it. How is possible license it from you?
So, there's a chance we may be able to get super creative with how these cells look as well. Print the nano cells in one pattern and then screen print the solar cell on top of that in another pattern over it.
Want some to try .
Would these be powerful enough to light large indivdual channel letter or box signs on building facades?
ive heard this for 10 years now ahahahahahhaha
I still didn't get what will be the price per kilo watt hour eventually ?
非常棒的創新
Bravo 👏🏼 👏🏼👏🏼👏🏼👏🏼 !!!!!
Awesome👏👏👏
The formatting of this video and it’s description seems to imply that this is technology invented by MIT but that is simply not the case? Slot die printing of solar cells has been around for years now and is certainly not something one can attribute as a recent breakthrough from MIT. Perhaps the description could be altered and clarify that this is not an MIT invention but rather just continued development of what has already existed for years, as severe people in the comments seem to be confused. Awesome work though!
Weight is only one factor. How much power per square meter is generated v. conventional solar cells???
Marvelous
When will it be aviable ?
Where can we buy this?
TV's will be next, just roll it out and hang it up.
Wooww this is amazing I like too now more about it
Wow incredible👏👏👍
One might use these to make artificial leaves and then artificial plants that then can generate electricity but look like plants.
This could have both commercial and military applications.
BTW, I just made a video and uploaded it my RUclips channel that describes the latter.
Not me watching mit videos the school I will never get into
The pain I'm feeling
Weight on a home's roof is fairly irrelevant since homes don't move and an extra 1000 lbs wouldn't require reinforcement. Great for vehicles though.
Impressive
Is it resistant to use on exterior of buildings during extreme heat/cold times over seasons. Amazing advancement.
What is the efficiencies of these cells.
so the team is re-developing dyneema who exist since 10 years ? Interesting
Isn't this pervoskites?
