Hydrogen produced with light

HZB researchers have developed a new semiconducting structure, which uses sunlight to split water and produce hydrogen. It is made from a substrate of Chalcopyrite, coated with Titaniumdioxide, both inexpensive materials. See, how this structure is produced.
The research is embedded in the program Light2hydrogen, sponsored by the German Ministry for Education and Research (BMBF).

This is excellent. This is what I'm studying.

awesome work!

how to make the tio2 paste on the glasses?

[@diveflyfish]

Nice application of the semiconductor..... Was the doping agent Galena or Manganese?

[@crazevlogger]

Can we use water instead of h2so4 and using normal light incident on the chalkopyirite coated with titanium dioxide???

[@antoniarotger2899]

Try it out. I think you need the H2SO4 in order to increase the mobility of ions in the water. I would recommend to have a look in the literature. Here: onlinelibrary.wiley.com/doi/10.1002/aenm.201402148

Can you maken a lightbulb? ..sulphuric acid?

[@PK.Civil.Servant]

Good

[@oudotcom]

Do you need to ground the electrode, or why do you use this electrode cable on the stuff ?

[@ganeshbabumariappan6555]

I'm also having same doubt

[@yogesh2707]

[@freegreeninnovation]

:))

[@CatboyChemicalSociety]

yes you need this and if you have a PEM between the active photocatalyst and the ground electrode on the other side facing away from the sun you can collect hydrogen and oxygen seperately.

[@joshuanorris9785]

can you capture all lost elements with this technique?
