Abstract

interface. As a result, the PCEs of both devices with SR-1 and SR-2 IFLs outperformed those of the pristine device. The best performance of 20.3% efficiency with nearly negligible hysteresis was achieved from the device with SR-1. Furthermore, the devices with SR molecules achieved remarkable thermal stability under continuous heating at 60 °C and 50-60% relative humidity, highlighting the potential of SR-based IFLs for stable and efficient PSCs.
