I am a free-energy enthusiast and am trying to build a solar cell in which the light that is reflected and focused by a parabolic mirror can power. Being that the light is focused, I think that it will produce more wattage than normal. However, I can't find a solar cell that will produce enough watts or current for the 6in. circle of focal point. Maybe if the cell was more dense or something. This really has me stumped and I'd really appreciate any answers that anyone could provide. Thanks.

You should watch the episode of mythbusters where they try to build a death ray with mirrors and need a focal point, they make a mirrior in a contact sorta shape and the light focases on it. if you could make a solar cell like that maybe it would work. The episode was on all weekend, it might be helpful for some other things too!

You could try looking at Peltier thermionic generators, (ref. http://www.peltier-info.com/generators.html) which deal directly with the heat input rather than light; they can get a lot higher power density per square inch, and cost about the same per watt as a solar panel. I suppose you already know that there are about 800 watts/sq. meter on Earth's surface (1400 in free space), and solar panels are about 15% efficient. When they get very hot, your efficiency will drop, though, so you might be seeing that effect.
