The Photoelectric Effect in Photocells

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons and photons. They throw wads of paper to model the lighting of a bulb. This is a memorable activity that will make solar cell operation clear in their minds.
