Abstract:
Perovskite are organic-inorganic hybrid materials. The organic component of the perovskite decomposes rapidly due to humidity and moisture exposure. Cesium (Cs) has successfully been proposed as the alternate A-cation in the perovskite material. Cs is purely organic material that has comparatively low degradation due to humidity. In this work nontoxic gallium-based cesium perovskite absorber is used in the PSC. The Cs-PSC is numerically modelled through solar cell capacitance simulator (SCAPS-1D). ZnSe has been chosen as ETL in the structure due to having large band gap and transmittivity. While kesterite CMTS material has been used as the HTL due to its high electric conductivity. The effect of Cs-perovskite and the CTL on the photovoltaic cell’s performance are analyzed in detail though using continuity and Poisson equations. The IV characteristics, electric potential, recombination, band alignment, power conversion and quantum efficiency are studied. Moreover, the effect of increasing absorber defect density on optimized thickness of the layer has also been found. The optimized thickness at defect density of E13 was found to be 0.9 µm with PCE of 19.66%, for E14 0.8 µm with 19.54% PCE and for E15 0.8 µm with 19.34% PCE
