Polycrystalline silicon rods recovery, Yunnan polysilicon recycling (certification), Lijiang polysilicon recycling

Different impurity elements contained in different metallurgical grade silicon, but the main impurity is basically the same, including impurity elements Al, Fe, Ti, C, P, B and so on. And for different impurities also studied some effective removal method. Preparation Method since 1975 Wacker polysilicon material used casting company since, metallurgy Preparation of solar-grade polysilicon is considered an effectively reduce production costs, specifically targeted at multi-grade polysilicon solar production process Monocrystalline silicon recycling to meet the photovoltaic industry the rapid development needs. For different nature of impurities, preparation of solar grade polysilicon technology roadmap Photovoltaic Technology Co., Ltd. Yan Zhen Xin wafer recovery, solar cell recycling, recovery native polycrystalline, silver cloth recycling, recycling of monocrystalline silicon, polycrystalline silicon recycling, solar cells Recycling polysilicon recycling, photovoltaic module recycling, electronics recycling, metals recovery, circuit board recycling, sapphire recycling. Polysilicon production technology continues to progress, automatic casting furnace each production cycle (50 hours) to produce 200 kilograms or more of silicon ingots, grain size centimeter; [4] Research and nearly a decade since the single crystal silicon technology rapid development, where technology is also being applied to the production of polycrystalline silicon cells, such as selective etching emitter junction, back surface field, corrosion suede, surface and bulk passivation, thin metal gate electrode, using screen printing technology allows the gate electrode width down to 50 microns, a height of 15 m or more, a rapid thermal annealing techniques for the production of polycrystalline silicon can significantly shorten the process time, process time to complete monolithic thermal head and tail polysilicon recovered within one minute, using the technology in a 100 square centimeter piece made of polycrystalline silicon cell conversion efficiency of more than 14%.
