Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same.
The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.
