High-performance hole transport layer based on WS2 doped PEDOT:PSS for organic solar cells
Source abstract
Abstract
Abstract In this work, we developed WS2 nanosheets (WS2 NS) doped into PEDOT:PSS (PEDOT:PSS/WS2 NS) as an efficient hole transport layer (HTL) for organic solar cells (OSCs). WS2 NS is obtained by a simple and cost-effective liquid-phase exfoliation (LPE) method. The results show that the PEDOT:PSS:WS2 NS anode interlayer has higher work function, reduced roughness and improved hole mobility. The devices based on PEDOT:PSS:WS2 NS interlayer show enhanced extraction and transportation of holes and improved fill factor and short-circuit current density. Based on PM6:Y6, the power conversion efficiency (PCE) increased from 14.35% to 15.67% after WS2 NS doping.
