A model for the CdS solar cell

The CdS solar cell is a photovoltaic device made from a thin-evaporated film of CdS and a chemically formed layer of copper sulfide. A model is presented which describes the formation of the p-type copper-sulfide layer into the n-type CdS material and the resulting p-n junction. The model explains the physical, electrical, and electrooptical properties of the device and its mode of operation.
