Solar grade silicon can be produced from quartz following a two-stage process consisting of the production of metallurgic silicon and its further purification up to solar grade quality. The two most used processes are Siemens and Fluidized Bed Reactor, FBR, from Union Carbide. Siemens process was patented by Siemens Corporation in the 1950's.
Thus, the development of optimized processes for production of cheap Si (SG) feedstock material can allow better competitivity. Solar grade silicon can be produced from quartz following a two-stage process consisting of the production of metallurgic silicon and its further purification up to solar grade quality.
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.
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.
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).
In spite of the confusion on absolute cost, there is general agreement that the single largest operational cost driver for solar grade silicon production is energy consumption. Large energy consumption impacts negatively silicon economics, energy pay-back time and carbon emissions of PV.
