Avoid the scams out there saying you can build your own panel for $200 to power your whole house. You can’t. There are some free instructions on the You Build It site that are legit.

You can make some of the make shift solar cells out of the deposite formed on copper when super heated. There are some tutorials online that explain how to do it,.
Your best bet would be to buy solar cells which are made from different processes and test them.
example
monocrystalline solar cell
polycrystalline cell
amorphous cell (not realy a cell, but a piece)
there are many other types of cells. Just contact someone and ask for a cell for school, they are about $2 a piece.
Then get a good multimeter from radio shack and do all of your testing on the same day.
