Oddly, and contrary to some opinion, the big private investors in solar cell tech are big oil. Shell is a major. There are some $2 per watt products but they are not available to the ordinary consumer. If you are running a publicly funded project you can get this. But, it still isn’t in the five cents range that would bring solar power to 6.5 billion people.
Can you tell me more about the publicaly funded projects. By FReepMail if that is easier. Actually a subject of particular interest right now.

I wonder how much of that is just PR so they can be seen to be “doing something” about alternative energy sources?
