Photovoltaic cell

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

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 [].
