5.1. Silicon wafer fabrication The vast majority of silicon solar cells in the market are fabricated on mono- or multicrystalline silicon wafers.

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.
