Here's a Solar-powered Phone

I was trying to build a clip-on solar-panel thingy for existing cellphone units last year. I bought some of the necessary materials to build a prototype but none of it worked. Voltage and current were such that the Nokia phones failed to charge. Transistors were first proposed to increase voltage but nothing came of the project since my friend the engineer was too busy with his day job. Right now, I'm thinking of using a capacitor linked to photovoltaic cell to charge a cellphone. Now, if I could only drag my butt off to work on it.
