Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from am
1.1.1 Working principle of photovoltaics Conventional p-n junction and excitonic solar cells have different working principles. A conventional photovoltaic consists of p-type and n-type semiconductors. When the energy absorbed is equal to or larger than the band gap energy of the semiconductor, elec...
The working principle of solar cells is based on photovoltaic effects. It means excitation of electrons from the valance band to the conduction band of the light absorber, which is a semiconductor, and transferring of electrons and holes. The circulation of electrons after excitation and ...
