摘要：

MoS2-graphene (M-G) hybrid was prepared by a hydrothermal method and used as counter electrode materials in CdS quantum dot-densitized solar cells (QDSSCs). Under simulated solar light irradiation, the cell with M-G counter electrode has higher efficiency than that of Pt and bare MoS2 counter electrode owing to the synergistic effects between MoS2 and graphene. The electrochemical impedance spectroscopy (EIS) and Tafel-polarization measurements reveal that M-G counter electrodes show better electrocatalytic activity. Moreover, the fabricated cell, shows high efficiency (6.23%) under weak light intensity (25 mW/cm(2)). (C) 2017 Elsevier B.V. All rights reserved.
