Problem

It is possible to convert radiant energy into electrical energy using photovoltaic cells.

Assuming equal efficiency of conversion, would infrared or ultraviolet radiation yield more electrical energy on a per-photon basis?

Solution

We’re being asked to identify which would yield more electrical energy: infrared or ultraviolet radiation


Recall that in the electromagnetic spectrum, radiation:

• On the left side: has high energy and frequency and a low wavelength

• On the right side: has low energy and frequency and high wavelength
