Photovoltaic pv effect
Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
Photovoltaic Effect
Photovoltaic effect refers to the phenomenon that light causes a potential differences between different parts of a non-uniform semiconductor or a combination of a semiconductor and a metal.
