The production of silicon solar cells The production of a typical silicon solar cell ( Fig. 2) starts with the carbothermic reduction of silicates in an electric arc furnace. In this process large amounts of electrical energy break the silicon–oxygen bond in SiO 2 via an endothermic reaction with carbon.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
The production of solar-grade silicon, that is mainly used in solar and electrical applications, from metallurgical-grade silicon requires the reduction in impurities by five orders of magnitude via the so-called metallurgical route [5, 6, 7, 8]. Directional solidification (DS) is an essential step in this approach.
Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics Silicon (Si) is the dominant solar cell manufacturing material because it is the second most plentiful material on earth (28%), it provides material stability, and it has well-developed industrial production and solar cell fabrication technologies.
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.
The silicon substrate is converted into solar cells using technologies based on semiconductor device processing and surface-mount technology (SMT). The cell process technology (Sect. 51.4) mainly consists of wafer surface etching, junction formation, antireflection coating deposition, and metal contact formation.
