Monocrystalline silicon modules are currently the fastest-developed photovoltaic modules and have been widely used in space and on the ground. The solar cells in the monocrystalline silicon module use high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.999%. At present, the monocrystalline silicon modules used on the ground use solar-grade monocrystalline […]
