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 [].
A photovoltaic cell is an electronic component that converts solar energy into electrical energy. This conversion is called the photovoltaic effect, which was discovered in 1839 by French physicist Edmond Becquerel1.
