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 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.
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.
The silicon solar cell value chain starts with the raw materials needed to produce Si, which are SiO 2 (quartz) and C-bearing compounds like woodchips and coke. Through the submerged arc furnace process or carbothermic reduction process, metallurgical-grade silicon (MG-Si), with 98% purity, is obtained.
Silicon-based solar cells are still dominating the commercial market share and continue to play a crucial role in the solar energy landscape. Photovoltaic (PV) installations have increased exponentially and continue to increase. The compound annual growth rate (CAGR) of cumulative PV installations was 30% between 2011 and 2021 .
