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.
The traditional method of production required 90 kWh of electricity for each kilogram of silicon. Newer methods have been able to reduce this to 15 kWh/kg. This still means that, depending upon its efficiency and the location of the device, a silicon solar cell can take up to 2 years to generate the energy used to make it.
Silicon, abundant and more efficient as a semiconductor, quickly became the preferred material for solar cell production. This transition was driven by the need for higher efficiency and the scalability of silicon, which allowed for broader commercial and residential applications.
A solar cell in its most fundamental form consists of a semiconductor light absorber with a specific energy band gap plus electron- and hole-selective contacts for charge carrier separation and extraction. Silicon solar cells have the advantage of using a photoactive absorber material that is abundant, stable, nontoxic, and well understood.
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.
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).
