Simulating Proton Radiation Tolerance of Perovskite Solar Cells for Space Applications
Advanced Energy and Sustainability Research, Volume 4, Issue 12, December 2023., 2023 Dang‐Thuan and co‐authors suggest a novel approach for predicting proton‐radiated degradation in perovskite solar cells. They combine ion scattering and optoelectronic simulations to overcome experimental constraints. FAMAPbI3‐based (lighter materials) cells show higher radiation tolerance than CsPbI2Br (heavier materials).
