A perovskite solar cell is a type of solar cell which includes a perovskite structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials such as methylammonium lead halides are cheap to produce and simple to manufacture. The perovskite solar cell module industry would be increased rapidly in the following years just like the development of second generation solar cell. According to our forecast, China will be the most important perovskite solar cell module supplier and have the capacity share more th...
