Interface Engineering with Nb2CT x MXene Electron Transport Layer for Defect-Controlled Lead-Free MASnI3 Perovskite Solar Cells
Lead-free tin-based perovskite solar cells offer environmentally sustainable alternatives to conventional lead-based perovskite solar cells but suffer from high defect densities and poor interfacial charge selectivity, which limit their efficiency and stability. This work presents a comprehensive numerical study of N...
