Abstract

A novel hole transport layer (HTL) composed of ultrathin two-dimensional, molybdenum disulfide (MoS₂) sheets decorated with 20 nm gold nanoparticles (NPs) (MoS₂@Au) was developed to make use of plasmonics for organic solar cells (OSCs). Both experimental and theoretical simulations revealed that the device with the MoS₂@Au composite as the HTL exhibited enhanced short-circuit photocurrent density (J_sc) and efficiency compared to that with MoS₂ alone as the HTL.
