Hydrogen-Bonding-Guided Molecular Pair Suppresses Self-Aggregation for Uniform Passivation of Efficient Inverted Perovskite Solar Cells

Abstract Surface passivation is critical for high-performance perovskite solar cells (PSCs), yet achieving a uniform molecular layer is hindered by uncontrolled molecular aggregation, thereby limiting passivation efficiency. Here, we introduce an aggregation control strategy usin...

Natural pigment-based semiconductor isomers as interfacial layers in organic photovoltaic devices

Purpose This study aims to develop bio-based interfacial materials for organic photovoltaic applications by engineering carotenoid-derived molecular frameworks with favorable energy level alignment and enhanced light-harvesting capability. Design/methodology/approach Three diphen...
