Scaling of All-Inorganic Perovskite Solar Cells through Improved Thermomechanical and Optoelectrical Stability

Currently, silicon solar cells are the industry standard for solar technology. However, perovskites solar cells (PSC) have recently proven to be a competitor due to its potential for low-cost processing and high efficiency. All-inorganic CsPbI3 is a group of perovskites that have been proven to be more compositionally and thermally stable in comparison to their organic counterparts. However, the tradeoff of poor phase formation leads to highly tensile films that are known to significantly reduce stability. This research shows a stabilized phase and improved durability of all-inorganic CsPbI3 films through the polymer polyvinylpyrrolidone (PVP) as a precursor additive.
