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 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.
The processes that follow are obtaining solar-grade silicon (SG-Si) and the production of mono- or polycrystalline silicon (ingots) with a good crystallographic structure. The ingots are then cut into thin wafers from which the PV cells are then manufactured.
The market for solar modules has evolved in recent years, moving away from the relatively exclusive, ribbon-based connection of full-square solar cells to a range of cell formats and connection technologies that are constantly improving performance (e.g., split cells, shingled cells, high-density cell interconnection). 3.7.5.
The impurity content of titanium should be <50 ppm, iron should be <0.1%, phosphorus should be <0.001% and sodium should be <0.01%. Impurities of iron and transition elements become sources of defects in the cell and impair the performance of the solar cell, which is why they are listed in the ppm range.
This, in turn, affects the solar cells’ properties, particularly their efficiency and performance. The current laboratory record efficiencies for monocrystalline and multicrystalline silicon solar cells are 26.7% and 24.4%, respectively .
Even higher energy consumption is required for the purification process to solar-grade Si. Therefore, it is of utmost importance to design proper waste management practices …
