Solar cells and absorption

In association with The Solar Spark at the University of Edinburgh

No comments

Investigate which wavelengths of light have the highest energy by measuring the current produced when a solar cell is illuminated with coloured light.

This activity demonstrates the ability of solar cells to absorb at different wavelengths of the electromagnetic spectrum and shows how the more it can absorb, the more power it produces.
