分别以不同质量的生物分子牛血清蛋白为模板剂,制备了不同大小粒径的ZnO半导体材料,并将其用作染料敏化太阳能电池的光阳极材料。结果发现,大颗粒(粒径为600 nm)的光电效率为0.473%,低于小颗粒(粒径为100 nm)的0.645%的光电效率。研究发现,粒径大小对ZnO染料敏化电池的短路电流密度有较大的影响,粒径越大,短路电流密度越小。随着牛血清蛋白量的增加,ZnO纳米粒子的粒径逐渐增大,短路电流密度依次减小。当牛血清蛋白加入量为0.05 g时,ZnO基DSSC的光电转换效率最高。

With different quality of bovine serum albumin as the template agent respectively, the different sized particles of ZnO semiconductor were synthesized and prepared to different DSSC. The results showed that the larger particles (size is 600 nm) had a photoelectric efficiency of 0.473%, which below the 0.645% of the smaller particles (particle size is 100 nm). Studies have found that the size of the particle size of ZnO has a great influence on the short circuit current density and the IPCE of DSSC:the smaller the particle size, the greater the short circuit current density and the IPCE. When the quality of bovine serum albumin is 0.05 g, the DSSC of ZnO has the highest IPCE.
