I want to know how to make a sample solar cell which can generate power of a very small magnitude. What material is required and how would I assemble it to make a simple solar cell?

  • \$\begingroup\$ Copper Oxide solar cells can easily be made "at home'. Power out is utterly minimal - but they are a true photovoltaic device. \$\endgroup\$ – Russell McMahon Feb 27 '14 at 9:38

Shining bright sunlight on an LED or any optical, junction device (photodiode etc.) will cause it to generate a very small amount of electricity - you might have a play with that phenomenon.

For my optoelectronics class final project, my group attempted to make a nanocrystalline titanium dioxide solar cell. Short of having access to silicon fab equipment, I think this dye-sensitized solar cell is the best you can do.

The (slightly) less-common materials it uses are:

  • Tin-oxide-coated glass plates/slides
  • Nanocrystalline TiO2
  • Potassium iodide

Ours ended up failing, I believe it was because the consistency of our TiO2 paste wasn't that good, or some possible shorts between the plates. This seems to be a fairly common educational cell, and the mechanism of action is well-described.
