A photocell is made up of a semiconductor, the working of which is dependent on the intensity of incident light. When the amount of light exceeds a certain frequency, the electrons...
How Do Photocells Work?
A photocell, or photovoltaic cell, turns light into electricity. It is made of two kinds of semiconductor materials. A semiconductor when connected to a source of electricity conducts some electricity, but not as much as metal would. The two...

Nearly all photocells will have slightly different specifications, although they all
pretty much work the same. If there's a datasheet, you'll want to refer to it.
