Development status of inverted perovskite solar cells

While the population has exploded, the world's energy demand has also risen exponentially. Energy pollution is also very severe. Therefore, it is urgent to increase the utilization of renewable new energy. Solar power has the greatest potential in the new energy sources. One kind of solar cell is the inverted perovskite solar cell (I-PSC). It has the advantages of simple device structure, high absorption coefficient, small hysteresis effect, and good defect tolerance. In this paper, the effects of electron transfer, hole transportation and manufacturing technology on the appearance of inverted perovskite-type solar cells are discussed, also the foreground of their commercialization is presented. It is believed these processes are a small step for ameliorating the photoelectric conversion efficiency and stability of these devices.
