Abstract

En 中文

• Chiral ligands were introduced into the perovskite precursor to modulate electronic structure and interfacial properties. • Enhanced crystallinity and regulated microstrain in perovskite films were confirmed by XRD and microstrain analysis. • Reduced non-radiative recombination loss from 354 mV to 304 mV, boosting the average Voc to 1.16 V. • Chiral interface engineering provides a scalable strategy to bridge the Voc gap and improve PSC efficiency and stability.
