Enhanced resistance to degradation in sprayed perovskite CH3NH3PbI3 induced by the temperature

Abstract

When compared to solar cells made from other materials, perovskites provided better performance in organic or inorganic hybrid solar cells. But one of the biggest problems facing scientists working in the photovoltaic industry right now is improving the stability of Perovskite solar cells. Despite their enormous potential, which exceeds that of traditional photovoltaic solar cells, these cells' low stability inhibits their commercialisation. In the current study, we looked at how the temperature of the substrate affected the physical characteristics of Perovskite thin films produced by spray pyrolysis using a moving nozzle. X-ray diffraction, scanning electron microscopy pictures, ultraviolet and visible absorption spectroscopy, and other methods were used to characterize the produced films. The results demonstrate that 90°C is the ideal deposition temperature.
