Abstract

Abstract : Flexible perovskite solar cells based on polydopamine cross-linked NiO x exhibited over 70% efficiency retention after 1000 bending cycles. Abstract : Bendable nickel oxide (NiO x ) was first fabricated via polydopamine (PDA) modification and applied as an interfacial layer in flexible perovskite solar cells. PDA cross-linked NiO x could release mechanical stress to eliminate the inherent brittleness of inorganic crystals, leading to a flexible device exhibit over 70% retention of efficiency after 1000 bending cycles.
