Carrier photodynamics in 2D perovskites with solution-processed silver and graphene contacts for bendable optoelectronics

Abstract Silver (Ag) and graphene (Gr) inks have been engineered to serve as efficient electrical contacts for solution-processed two-dimensional (2D) organo-halide (CH3(CH2)3NH3)2(CH3NH3) n−1Pb n I3n+1 (n = 4) layered perovskites, where all inkjet-printed heterostructure photodetectors (PDs) were f...
