Perovskite solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials.As a new generation of photovoltaic technology,perovskite solar cells have the following advantages over traditional crystalline silicon: less raw material usage,only 1\/1000 of crystalline silicon,and low material purity requirements;high photoelectric conversion efficiency,up to more than 30%,exceeding the conversion limit of crystalline silicon,and the efficiency of perovskite and crystalline silicon stacking can reach more than 33%;low temperature coefficient, good weak light power generation, the actual single watt power generation is 5-10% higher than that of crystalline silicon modules;low cost, more than 40% lower than that of crystalline silicon modules.<\/p>\n\n\n\n
