摘　　要：为了降低染料敏化太阳能电池对电极的成本,通过碳化旋涂在导电玻璃基底上的金属有机框架薄膜制备纳米多孔碳对电极,采用SEM和EIS分别对多孔碳电极的形貌、结构和电极性能进行表征,并将金属有机框架配合物在不同碳化条件下所得多孔碳电极作为对电极,以方酸敏化Ti O2纳晶薄膜作为工作电极,组装成染料敏化太阳能电池,通过测定电池的J-U数据分析不同多孔碳材料的催化性能.结果表明:控制碳化金属有机框架薄膜条件可以制备结构和形貌可调的多孔碳电极,碳化温度和时间是影响多孔碳电极微结构和光电性能的主要因素,400℃下碳化4 h所得多孔碳对电极组装的方酸敏化太阳能电池的光电转换效率最高,达到1.01%,高于常用的铂电极.In order to lower costs of dye-sensitized solar cell,nanoporous carbon electrode was prepared by carbonizing the metal organic framework thin film screen printed on conductive glass. The morphology,structure and performance of porous carbon electrode were characterized by SEM and EIS. Metal organic framework complexes in the porous carbon elec-trode under different carbonization conditions were used as the counter electrodes,and squaric acid sensitized Ti O2 nanocrystalline thin film were used as the working electrodes,assembling into dye sensitized solar cell,the catalytic prop-erties of different porous carbon materials were analyzed by J-U data of cells. The results show porous carbon electrodes with the controlled structure and morphologies can be prepared by changing the carbonization conditions. The carbonization tem-perature and time are two main factors to decide the structure and photoelectric properties of porous carbon electrode. Squaric acid sensi-tized solar cell based on the porous carbon counter electrode prepared by carbonizing at 400 ℃ for 4 h show the highest photoelectric conversion efficiency of 1.01%, which is higher than that of the most used Pt electrode.
