Solar cell photovoltaic effect excited electrons hole

In most photovoltaic applications, the source is sunlight, and the devices are called . In the case of a semiconductor p–n (diode) junction solar cell, illuminating the material creates an electric current because excited electrons and the remaining holes are swept in different directions by the built-in electric field of the depletion region. The AC PV is operated at the non-equilibrium conditions. The first study was based on a p-Si/Ti. [pdf]
