摘　　要：利用银纳米线(Ag NWs)和不同浓度二氧化钛(TiO 2)共混形成稳定杂化墨水,将其在玻璃衬底上制备成透明导电薄膜,用于替代染料太阳敏化电池(DSSC)中造价昂贵的掺氟氧化锡(FTO)电极材料。结果发现,实验中的Ag NWs/TiO 2复合电极的导电性和透光性都较优异,其中最优的复合导电薄膜在550nm波长处透光性达到了89.3%,表面方阻为79Ω/sq。组装成器件后,以N719为染敏剂时,复合电极的光电转化效率达到了2.07%,短路电流Jsc为3.50mA/cm 2,开路电压Voc为0.61V,填充因子为51%,为未来大面积卷对卷生产提供了可能。Silver nanowires(Ag NWs)and titanium dioxide(TiO 2)of different concentrations were used to blend to form stable hybrid ink,which was prepared into transparent conductive film on glass substrate,and was used to replace the expensive fluoro tin oxide(FTO)electrode material in dye sensitized solar cells(DSSC).The results showed that the transparence and coductivity of the Ag NWs/TiO 2 composite electrodes were excellent and the optimized composite film maintain high transparency with a transmittance of 89.3%at 550 nm,and low surface sheet resistance of 79Ω/sq.As a result,the DSSC of composite film has a hig power conversion efficiency of 2.07%,Jsc=3.50 mA/cm 2,Voc=0.61 V,FF=51%.It provides a possibility for large area roll-to-roll production in the future.
