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

Perovskite solar cells (PSC) have recently risen in popularity as a competitor to traditional silicon solar cells due to its potential for low-cost processing and tunability. All-inorganic CsPbI3 is a type of high bandgap perovskite that is more compositionally and thermally stable in comparison to their organic counterparts, making it ideal for tandem solar cells. However, CsPbI3 has poor phase stability and requires high formation energy, resulting in poor performance and stability. In this study, the research team aims to understand the photoluminescent and ionic properties of CsPbI3 under thermal aging and light exposure.
