Does anybody have information on the decades old method of making solar cells using thin copper plates and heating it up then connecting to both surcaces of the plate.

somewhere I read an article about it but cannot seem to recall where so I am asking what anyone has experienced with this method.

A copper oxide rectifier can be made but I am not aware of a way to make a solar cell.

Iv also seen that someware but it produces a max of 100nA at a few mV so you cant power anything whith it.

Google "copper oxide photocell". The first hit is relevant.

Lindsay Technical Publications ( http://www.lindsaybks.com/ ) used to sell a booklet on rolling your own (albiet inefficient) photovoltaic cells. Check out their web site. Their catalog is wonderful reading for experimenters and DIYers.

Thermocouples generate electricity, but in the millivolts range. You would know probably use them to measure temperature. But yes they can generate electricity...very small amounts.

If you have a bookstore like B&N near by take a look at "Solar Energy Projects for the Evil Genius". Page 87 has a project that walks you through building an inefficient thin-film cell.
