What is a polycrystalline silicon solar cell?
Although monocrystalline silicon solar cells have their advantages, their high price hinders the development of monocrystalline silicon solar cells in the low-cost market. The polycrystalline silicon solar cell is the first to reduce costs, followed by efficiency. Although polycrystalline silicon solar cells and monocrystalline silicon solar cells have different crystal structures, the photovoltaic principle is […]
