英文摘要	Here we report a facile one-step solution-phase process to directly grow ultrathin MoS2 nanofilms on a transparent conductive glass as a novel high-performance counter electrode for dye-sensitized solar cells. After an appropriate reaction time, the entire surface of the conductive glass substrate was uniformly covered by ultrathin MoS2 nanofilms with a thickness of only several stacked layers. Electrochemical impedance spectroscopy and cyclic voltammetry reveal that the MoS2 nanofilms possess excellent catalytic activity towards tri-iodide reduction. When used in dye-sensitized solar cells, the MoS2 nanofilms show an impressive energy conversion efficiency of 8.3%, which is higher than that of a Pt-based electrode and very promising to be a desirable alternative counter electrode. Considering their ultrathin thickness, superior catalytic activity, simple preparation process and low cost, the as-prepared MoS2 nanofilms with high photovoltaic performance are expected to be widely employed in dye-sensitized solar cells.; National Thousand Young Talents Program of China; Young Scientists Project of National Basic Research Program of China (973 Program) [2015CB659300]; National Natural Science Foundation of China (NSFC) [21403105, 21573108]; China Postdoctoral Science Foundation [2015M580413, 2015M580408]; Natural Science Foundation for Young Scholars of Jiangsu Province [BK20160647, BK20150571, BK20150583]; Fundamental Research Funds for the Central Universities; Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD); SCI(E); EI; ARTICLE; zhongjin@nju.edu.cn; zgmin@pku.edu.cn; j.liu@duke.edu; 35; 16017-16025; 8
