There are generally three industries related to crystalline silicon solar cell and module production: metallurgical and chemical plants for raw material silicon production, monocrystalline and polycrystalline ingot fabrication and wafer fabrication by multi-wire saw, and solar cell and module production.
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).
PV Solar Industry and Trends Approximately 95% of the total market share of solar cells comes from crystalline silicon materials . The reasons for silicon’s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap.
The efficiencies of typical commercial crystalline silicon solar cells with standard cell structures are in the range of 16–18% for monocrystalline substrates and 15–17% for polycrystalline substrates. The substrate thickness used in most standard crystalline cells is 160–240 μm.
