Electronic Blockade of Shunting Pathways via Dual Insulator Contacts for High-Efficiency Wide-Bandgap Perovskite Indoor Photovoltaics

Highlights Dual insulator contacts integrating poly(methyl methacrylate) (PMMA)-based grain-boundary passivation and a hybrid PMMA/mesoporous alumina ultrathin composite buried-interface layer. Dual insulator contacts suppress shunting paths and nonradiative recombination in both the wide-band gap (...
