Abstract
In the quest for sustainable energy, perovskite solar cells have emerged as promising candidates due to their high power conversion efficiencies and excellent optoelectronic properties. This study focuses on SrZrS3, a lead-free chalcogenide perovskite, and its integration with various inorganic transport layers for enhanced photovoltaic performance. Using SCAPS-1D simulation software, the effects of different electron transport layers (ETLs) and hole transport layers (HTLs) on device efficiency were systematically explored. The device with a-Si:H as the HTL and ZnS as the ETL (aSi-3) shows the highest efficiency of 20.01 % resulting from better energy band alignment and reduced recombination losses. This study highlights the importance of optimizing transport layers for enhancing SrZrS3-based solar cells, offering insights for developing high-performance, lead-free perovskite solar cells.
