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 process from silica to PV module. Silica is the initial raw material after adding a reducing agent, such as petroleum coke, wood, or low ash coal that melted under high-temperature conditions to derive elemental silicon and obtain industrial-grade silicone raw materials.
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.
Data are available in Supplementary Information (#5). The environmental costs associated with silicon flows used in solar PV manufacturing include factors such as energy consumption, water usage, emissions of greenhouse gases and other pollutants, as well as the impact on local ecosystems and communities.
We discuss the major challenges in silicon ingot production for solar applications, particularly optimizing production yield, reducing costs, and improving efficiency to meet the continued high demand for solar cells. We review solar cell technology developments in recent years and the new trends.
