Molybdenum sulfide/reduced graphene oxide (MoS/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 MoS sheets could nucleate and grow taking GO as substrates and the MoS/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 couples in the electrolyte. Therefore, the cell adopting as-prepared MoS/RGO as counter electrode demonstrated high power conversion efficiencies (PCE) of 7.63%, which indicates ∼14% enhancement compared with the MoS-based (6.68%) device.
通过一步水热法，将二硫化钼/还原氧化石墨烯（MoS/RGO）多孔薄膜原位沉积在掺氟氧化锡（FTO）基底上。由于氧化石墨烯（GO）表面分布着含氧基团，因此 MoS 片可以以 GO 为基底进行成核和生长，MoS/RGO 薄膜可以与 FTO 紧密结合。基于电化学研究，电池性能的提高可归因于电导率、催化活性位和电解质扩散率的提高，这最终有助于在电解质中对 I/I 对的还原表现出高催化性能。因此，采用所制备的 MoS/RGO 作为对电极的电池表现出 7.63%的高功率转换效率（PCE），与基于 MoS 的器件（6.68%）相比提高了约 14%。
