Solar cells are devices used to convert sunlight into electrical energy. They are made of a number of photovoltaic (PV) cells, which are typically made of silicon. However, other materials, such as cadmium sulfide (CdS), can also be used to make solar cells.

CdS solar cells are made by coating a sheet of cadmium sulfide with a thin layer of zinc sulfide. A number of these cells can then be connected together to create a solar panel.

CdS solar cells are less efficient than silicon solar cells, but they are much cheaper to produce. This makes them a good option …
