In recent years, perovskite photovoltaic technology has offered enormous viability and dimensionality in solar cell research. As a light-harvesting active layer, Perovskite generated remarkable development in device efficiency of 25.7% for the single-junction solar cell, and over 33% for the perovskite/silicon tandem solar cell. Also, perovskite-perovskite tandem solar cell (also called all-perovskite tandem solar cell) shows great potential in device performance and achieved a power conversion efficiency (PCE) of 26.4%. Transitioning photovoltaic technology from the laboratory to commercial products, high PCE, low cost, long lifetime, and low toxicity are some of the critical factors to consider during material selection. Pb-halide …

Third generation photovoltaics, including perovskites, are essential to improving solar technology for widespread future use. Perovskite solar cells have surpassed 23.7% power conversion efficiency, comparable to traditional silicon photovoltaic panels. However, these perovskites are fabricated using lead-based compounds, posing toxicity issues. Furthermore, existing perovskites have limited thermal and moisture stability in ambient environments. In order to address toxicity and stability concerns, as well as to maximize photon absorption in solar cells through bandgap optimization, this effort focuses on the development of novel leadfree perovskite materials. A cesium platinum iodide composition is selected as a model system due to the theoretical …
