Band diagram illustration of the photovoltaic effect. Photons give their energy to electrons in the depletion or quasi-neutral regions. These move from the valence band to the conduction band. Depending on the location, electrons and holes are accelerated by drift electric field Edrift, which gives generation photocurrent, or by scattering electric field Escatt, which gives scattering photocurrent.

…carrier concentration, does not have the AC PV effect. In most photovoltaic applications, the radiation source is sunlight, and the devices are called solar cells. In the case of a semiconductor p–n (diode) junction solar cell, illuminating the material creates an electric current because excited electrons and…
