2018 Solar Column Lights: Feasibility Analysis of Mass Production of Cast Polysilicon

Compared with a single crystal, a polycrystalline silicon solar cell having low conversion efficiency and low cost, cast polycrystalline silicon refers to a method of melting silicon in a crucible and solidifying the melt from the bottom. A silicon melt is injected into the crucible to solidify it. In the same time as the single-product silicon ingot, a multi-product silicon ingot equivalent to 10 times of single crystal silicon poetry can be obtained by the casting method, so it has the characteristics of high production efficiency and low energy consumption (according to Yuzuo Meilong : The 133rd Research Report of the Applied Physics Society Crystal Engineering Society. Although polysilicon is not a transistor, it can be used in solar cells.
