摘　　要：以低成本的碳浆为原料、采用刮涂法制成了以FTO为衬底的碳薄膜,并在120℃到400℃的不同烧结温度下制备了碳对电极。通过循环伏安(CV)、电化学阻抗(EIS)和光电流密度-电压(J-V)特性曲线等测试方法研究了烧结温度对于碳电极电催化和光伏性能的影响。研究结果表明,碳膜的电催化活性随着热处理温度增加有明显提高。在所研究的碳电极中,煅烧温度在400℃的碳电极,其DSSC显示了最好的光伏性能,功率转换效率为0.92%。The carbon counter electrodes were fabricated via doctor-blading approach on FTO substrate using low cost carbon paste and sintering at various temperatures from 120℃to 400℃.The influence of sintering temperatures on their electrocatalytic and photovoltaic properties were investigated by cyclic voltammetry(CV),electrochemical impedance spectroscopy(EIS)characterizations and photocurrent density-voltage(J-V)characteristic curves.The results show that the carbon films demonstrate the evidently improving electrocatalytic activity with the increasing heat-treatment temperature.Furthermore,among all the carbon based devices,the DSSC based on the carbon electrode sintered at 400℃ exhibits the best photovoltatic performance with a power-conversion efficiency of 0.92%.
