Perovskite Solar Cells
In article number 2404234, Parthasarathy Venkatakrishnan, Yuan Jay Chang, Chih-Ping Chen, and co-workers propose utilizing polyarene-based molecules as hole-selective layers (HSL) to passivate interfacial defects in perovskite solar cells (PSCs). The optimized HSL efficiently mitigates perovskite defects, promotes energy alignment at the HSL/perovskite interface, and enhances the carrier transport efficiency of PSCs. The resulting indoor light efficiency is 41.80 ± 0.57% under 3000K LED illumination (1000 lux) with promising long-term stability.
