通过改变浆料中纤维素增稠剂的添加量，制备了一系列具有不同平均孔径和分布的介孔TiO 2薄膜。BET比表面积表明，对于具有3、5、10和15wt%纤维素增稠剂的样品，平均孔径保持在14-15 nm的中心，但孔径分布随着纤维素增稠剂添加量的增加而变窄。随着纤维素增稠剂的进一步增加到21和30wt%，平均孔径减小到13和11 nm，并且孔径分布也变得更窄。由含有15wt%纤维素增稠剂的浆料制备的样品显示出最好的结果：短路光电流密度13 mA/cm 2，开路光电压0.72V，填充因子0.68，转换效率6.4%。
A series of mesoporous TiO2 films with different average pore sizes and distributions were prepared by changing the addition content of cellulosic thickener in the pastes. The BET surface area shows that, for the samples with 3, 5, 10 and 15 wt % cellulosic thickener, the average pore size remained centered at 14–15 nm, but the pore size distribution became narrower with the increase of cellulosic thickener addition. With further increase of cellulosic thickener to 21 and 30 wt %, the average pore size decreases to 13 and 11 nm, and the pore size distribution also became much narrower. The sample, prepared from the paste with 15 wt % cellulosic thickener, shows the best result: short-circuit photocurrent density 13 mA/cm2, open-circuit photovoltage 0.72 V, fill factor 0.68, and conversion efficiency 6.4%.
