摘要：The lattice deformation and structural evolution of perovskite films in response to electric fields, temperature, and light limit the operational endurance of solar cells. We mechanically reinforced perovskite thin films by integrating a polymer-coupled monolithic single-layer graphene interface that led to a twofold enhancement in modulus and hardness. The synergistic effect of graphene and poly(methyl methacrylate) restricted photoinduced lattice expansion and decreased the deformation ratio from 0.31 to 0.08%, which minimized the structural damage caused by dynamic lattice evolution. Solar cell devices maintained >97% of their initial power conversion efficiency after maximum power point tracking for >3670 hours under full-spectrum air mass 1.5 global (AM 1.5 G) sunlight at 90 degrees C.
