As an appealing photovoltaic or pv material, metal halide perovskite yields high efficiency in solar cells. Nonetheless, the deep-level traps of minority service providers at the surface of the p-i-n perovskite solar cells can reduce nonradiative recombination. The accurate passivation of deep-level traps has actually been a major emphasis in increasing the power conversion efficiency (PCE) to the theoretical Shockley-Queisser restriction.
