Abstract
Abstract All inorganic perovskite nanocrystals attracted the scientific community owing to its interesting properties. Even though lead halide perovskites having many advantages, the decomposition in the presence of moisture is its major limitation. Herein, we are using this phenomena for the sensing of atmospheric humidity. A cost-effective sensor was developed by the dip-coating of CsPbBr3 to Whatman 40 filter paper. The complete disappearance of the emission from this perovskite coated filter paper was monitored using an ultraviolet chamber. Interestingly, with the increase in the relative atmospheric humidity, the decomposition of CsPbBr3 was found to be faster. In our experimental regime, 30–95% relative atmospheric humidity, we found the sensor is active. Apart from the sensing activity, by knowing the kinetics of decomposition of CsPbBr3 perovskites, new methodologies can be adopted for stabilizing solar cells made of lead halide perovskite as active material.
