Thiol Groups Reutilization on Chemical Bath Deposited Tin Oxide Surface Achieving Interface Anchoring and Defects Passivation for Enhancing the Performance and Stability of Perovskite Solar Cells

/perovskite interface is optimized. A champion device with the IAM structure achieved a power conversion efficiency (PCE) of 22.41% while it maintained 80% of its original PCE after placing at 65 °C in nitrogen filled atmosphere for over 300 h and in an environment at 25 °C and 50 ± 5% relative humidity for over 1000 h, respectively.
