The AC PV effect is the generation of alternating current (AC) in the nonequilibrium states when the light periodically shines at the junction or interface of material. The AC PV effect is based on the capacitive model that the current strongly depends on the frequency of the chopper. See more The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical and chemical phenomenon. The photovoltaic effect is closely related to the See more The first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l'Académie des sciences See more In most photovoltaic applications the radiation is sunlight, and the devices are called solar cells. In the case of a semiconductor p–n (diode) junction solar cell, illuminating the … See more In addition to the direct photovoltaic excitation of free electrons, an electric current can also arise through the Seebeck effect.
