▎ 摘　　要

A hybrid material has been fabricated by combining MoS2/reduced graphene oxide (RGO) nanocomposites with carbon nanotubes (CNTs) (designated MoS2/RGO-CNTs) through facile electrophoretic deposition. The MoS2/RGO-CNTs hybrid benefits from the advantages of both MoS2/RGO and CNTs as a counter electrode (CE) in dye-sensitized solar cells (DSCs). According to a series of electrochemical results, the incorporation of conductive networks of CNTs provides additional pathways for electron transport in the MoS2/RGO-CNTs hybrid, which increases the charge-transfer rate at the CE/electrolyte interface. As a result, the MoS2/RGO-CNTs CE exhibits greatly improved electrocatalytic activity compared with that of MoS2/RGO alone. A DSC incorporating the MoS2/RGO-CNTs CE achieves impressive cell performance of 7.46%, which is higher than those measured with DSCs incorporating MoS2/RGO CE (6.82%) and Pt CE (7.23%).
