HIGH EFFICIENCY PEROVSKITE SOLAR CELL AND METHOD FOR MANUFACTURING SAME

摘要

According to the method of manufacturing a perovskite solar cell of the present invention, by a process of first modifying the surface of the electron transport layer with an alkali metal halide, coating the perovskite precursor solution thereon and then annealing, alkali metal and halide can diffuse into the perovskite crystal and passivate the defect trap. Accordingly, the present invention can provide a high-efficiency perovskite solar cell having long-term stability and very little hysteresis through effective doping of alkali metals and halides.
