  We use glass with a special conductive coating. Some titanium dioxide and then two layers of different organic chemicals. We then evaporate gold contacts on to the finished cell. The chemicals are easy to make and are really cheap. The gold…..not so cheap!

Hi!

We have a video on how solar cells are made: http://www.rsc.org/learn-chemistry/resource/res00000873/faces-of-chemistry-organic-solar-cells#!cmpid=CMP00001024.

It explains some of the materials used and how they work within the solar cell.
