All-inorganic perovskite solar cells (PSCs) offer excellent thermal stability, but lag in power conversion efficiency compared to hybrid PSCs. Researchers integrated a low bandgap organic active layer (PM6:Y6) to CsPbI2Br PSCs, extending the photo-response range, improving short-circuit current density, and boosting efficiency from 15.31% to 17.33%. This promising strategy demonstrates enhanced performance and deeper understanding of carrier transfer in integrated solar cells.

Transient photovoltage (TPV) and transient photocurrent (TPC) were performed on a Fluxim Paios characterization system with light intensity about 0.278 sun.
