The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight.These solar cells are composed of two different types of semiconductors—a p-type and an n-type—that are joined together to create a p-n junction joining these two types of semiconductors, an electric field is formed in the region of the
