Solar cell相关介绍：

Thin film solar cells are new photovoltaic devices to alleviate the energy crisis. Thin film solar cells can be made of low-cost ceramics, graphite, metal sheets and other different materials as substrates. It takes only a few to form a thin film thickness that can generate voltage μ m. At present, the maximum conversion efficiency can reach 18%. In addition to planar, thin-film solar cells can also be made into non planar structures because of their flexibility. They have a wide range of applications, and can be combined with buildings or become a part of buildings. They are widely used. The main products are CdTe, CIGS, GaAs, polysilicon films and other types.
