Here, R A is the ionic radius of A cation, R B is the ionic radius of B cation, and R x is the ionic radius of anion X. Generally, as for halide perovskite materials, the t is in the range between 0.81 and 1.11 and μ is in the range 0.44–0.90, while a lower (t < 0.8) or higher value (t > 1) will result in the structure distortion or the formation of alterative structures [].
Driven by the growing dominance of balance of system costs in photovoltaic installations, next-generation solar cell technologies must deliver significant increases in power conversion efficiency.
The results presented above demonstrate that the Ala complexed NiO can enhance the growth of perovskite, which leads to larger grains, fewer grain boundaries, and a more crystalline perovskite film, which in turn can reduce the number of defect sites where charges can recombine and help improve the performance of the device.
