Polyurethane-Encapsulated Mesoporous Carbon-Based Perovskite Solar Cells Resilient to Extreme Humidity and Mitigation of the Related Reversible J–V Bump

Salvatore Valastro, Gaetano Calogero, Emanuele Smecca, Valentina Arena et autres

Mesoporous carbon-based (mC) hole-transporting layer-free architectures offer a cost-effective solution for the commercialization of perovskite solar cells (PSCs). Adding 5-aminovaleric acid (AVA) to MAPbI 3 reduces defect concentration and enhances pore filling, while Eu enrichment in CsPbI 3 reduces cation migration and …
