摘要：

Molybdenum sulfide/reduced graphene oxide (MoS2/RGO) porous film was in-situ deposited on fluorine-doped tin oxide (FTO) substrates via a one-pot hydrothermal method. Due to the oxygen-containing groups distributing on graphene oxide (GO) surface, the MoS2 sheets could nucleate and grow taking GO as substrates and the MoS2/RGO film can be strongly linked to the FTO. Based on the electrochemical investigations, the enhanced cell performance could be ascribed to the improved electrical conductivity, catalytic active sites and electrolyte diffusion rate, which finally contribute to the high catalytic performance on the reduction of I-/I(3)(-)couples in the electrolyte. Therefore, the cell adopting as-prepared MoS2/RGO as counter electrode demonstrated high power conversion efficiencies (PCE) of 7.63%, which indicates similar to 14% enhancement compared with the MoS2 -based (6.68%) device.
