Make your own organic solar cells. Answered

I occasionally see questions from people wanting to know if they can make their own solar cells.

Previously, the answer was "no".


The latest issue of Science in School contains a "how to" for making organic solar cells from dyes instead of silicon, that produce useful amounts of electricity.

Link to "how to".

Also in this issue...

The archive of back issues is here (can you find my article?).

If you browse the magazine, and like it, you might consider passing the URL on to friends, colleagues and potential advertisers. Previously funded by an EU grant, the print magazine is distributed free. The website is funded until October 2010, but the print magazine needs finance (sound familiar?)

Anyway, if you are part of, or know of, a company that would like to target their advertising to science educators across Europe, point them at http://www.scienceinschool.org/advertising or contact them directly at advertising@scienceinschool.org


Why is Titanium Dioxide used? Why not copper oxide (II), because titanium dioxide has a large band gap it only absorbs UV light, where as copper oxide would absorb more of the spectrum.

Did you read the article? The TiO2 is not the photocathode material. It is (a) a mechanical substrate for the anthocyanin dye, and (b) a semiconductor carrier for the electrons liberated by the photoreaction of anthocyanin.

Interesting one..... May be a stupid question..... Is there a way to avoid conductive glass?

It's not conductive glass, it's glass with a conductive layer that you add yourself.

Yes! Now I can finally make a solar powered hat fan!

Interesting, there seems to be a lot of activity in this area: Homemade Solar Cells

and although this one here produces some power, 50 microAmps is not much power, but the video is older.
