I have been following solar energy for awhile. I am looking for information about ways to build solar cells at home. I have seen the article on heating a copper plate. It puts out microamps. What we need is a real usable type idea that could be constructed by the home experimenter. This would probably use some thin film technology such as CdTe. There may be a number of mixtures that are within reach of a home builder. I am looking to find a few people that have done this and can tell how to obtain the materials. There may be several technologies that could be used by the small scale builder. If you have some information, please join the discussion.
