Project Solar Energy

Carmen Said:

I'm doing a science project about solar energy. what is a good way to present it?

We Answered:

hook up a solar cell to a simple circuit.. voltage meter or oscillator with a speaker output.. and let someone put their hand over the cell, to block the light

best way to make this science, is to show how to derive the efficiency of the cell. perhaps show that focusing the light with a lens improves the efficiency

Discuss It!
