The photovoltaic effect is a fundamental phenomenon in the conversion of solar energy into electricity is characterized by the generation of an electric current when two different materials are in contact and exposed to
Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. Under short circuit conditions, there is no build up of charge, as the carriers exit the device as
