- Abstract
In this study, an eco-friendly (i.e., lead-free) tin-based halide perovskite solar cell (PSC) is proposed with remarkable high power conversion efficiency (PCE). To optimize the performance of the device, the architecture of a tin-based perovskite layer (PEA)0.2(FA)0.8SnI3 (PEA: phenyl ethyl ammonium, FA: formamidinium) with TiO2, IGZO, SnO2, and PC60BM as an electron transport layer (ETL); Spiro-OMeTAD, P3HT, PEDOT: PSS, and Cu2O as a Hole transport layer (HTL); and Au as an electrode has been investigated. The effect of numerous device parameters including absorber layer thickness, defect density, temperature, interface trap density, doping concentration, and bandgap, on photovoltaic device performance, has been studied. The superior device configuration is found to be IGZO/(PEA)0.2(FA)0.8SnI3/Cu2O/Au with 26.45% PCE, 1.0028 V open-circuit voltage (VOC), 31.89 mA/cm2 short circuit current density (JSC), and 82.70% fill factor (FF). Such a study shows that upcoming lead-free perovskite solar cells have a lot of potential to develop a wide range of eco-friendly photovoltaic devices.
