Implication

Research demonstrates improved efficiency of perovskite solar cells in air conditions, suggesting stabilization strategies with formamidinium.

Abstract

Achieving stable and efficient formamidinium (FA)-rich perovskite solar cells (PSCs) in airambient conditions remains a critical challenge. In this work, we demonstrate an antisolvent engineering approach for the triple co-solvent...
