Photovoltaic effect explained

The photovoltaic effect is the generation of voltageand electric current in a material upon exposure to light. It is a physical phenomenon. The photovoltaic effect is closely related to the photoelectric effect. For both phenomena, light is absorbed, causing excitation of an electron or other charge.
