I can't even find a solar cell capable of producing 6.3V for under 40 bucks after shipping & handling. I would like to solder it the solar cell to the circuit ... if i could build it that would be cool. I've seen a lot of solar cells and none of them match my criteria or budget. Any good links to solar cell suppliers would be appreciated. THANKS P.S. This is for a DC circuits class project (im a noob) and I dont actually know what the project is The Dr. said something about robotics kits.. I would much rather build something pragmatic (like a flash a to d converter on my breadboard and be done with it). My group members dont agree.
