The based structure of silicon solar cell Silicon absorbs the photons incident and generates at least one electron-hole pairs for each photon . The electric field generated in the PN junction will prevent the diffusion of the electrons to the side of P-type Si and the holes to the side of N-type Si.
The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
Evolution of silicon solar cell efficiency. The theoretical efficiency for photovoltaic conversion is in excess of 86.8% 1. However, the 86.8% figure uses detailed balance calculations and does not describe device implementation. For silicon solar cells, a more realistic efficiency under one sun operation is about 29% 2.
Silicon solar cells are likely to enter a new phase of research and development of techniques to enhance light trapping, especially at oblique angles of incidence encountered with fixed mounted (e.g. rooftop) panels, where the efficiency of panels that rely on surface texturing of cells can drop to very low values.
