Customer ServiceThe development of silicon-based photovoltaic (PV) cells began with the discovery of the photovoltaic effect by Alexandre-Edmond Becquerel in 1839.
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.
1. Introduction An important component of photovoltaic modules is the encapsulant, which is the material that surrounds solar cells and protects them from shock and environmental attack. The majority of modules use Ethylene Vinyl Acetate (EVA) as encapsulant material.
The efficiency of a PV cell is simply the amount of electrical power coming out of the cell compared to the energy from the light shining on it, which indicates how effective the cell is at converting energy from one form to the other.
Production of Solar Grade Silicon For the production of solar cells, the purity of solar grade Si (SG-Si) must be 99.9999% (grade 6 N). The electronics industry requires an even higher degree of purity, around 9–11 N, for the production of integrated circuits .
One of the most important improvements was the introduction of silicon purification techniques that resulted in a higher quality semiconductor material with fewer impurities, which had a direct impact on increasing the efficiency of PV cells.
