垂直导电衬底的ZnO纳米片的制备及其染料敏化太阳电池的性能

Preparation of Perpendicular ZnO Nanosheets and Their Performance of Dye Sensitized Solar Cell

介绍了二水乙酸锌/甲醇体系和硝酸锌/尿素体系制备垂直导电衬底的多孔ZnO纳米片、相应染料敏化太阳电池的性能以及制备垂直导电衬底ZnO纳米片体系的发展和现状。硝酸锌/尿素体系更易得到垂直导电衬底的多孔ZnO纳米片,而采用二水乙酸锌/甲醇体系,既可得到垂直导电衬底的多孔ZnO纳米片,也可得到由纳米片组成的多级结构微球。当前,硝酸锌/尿素体系制备的垂直导电衬底的ZnO纳米片的电池最高光电转换效率已达6.06%。

Zinc acetate/methanol and zinc nitrate/urea systems used to prepare perpendicular porous ZnO nanosheets were reviewed. The corresponding photoelectric properties of the dye sensitized solar cells were introduced emphatically. The development and present situation of zinc acetate/methanol and zinc nitrate/urea systems were also studied. Results show that zinc nitrate/urea system is more likely to get the perpendicular porous ZnO nanosheets. As for zinc acetate/methanol system, both perpendicular porous ZnO nanosheets and hierarchical ZnO microspheres consistied of porous ZnO nanosheets can be obtained under different preparation conditions. The photoelectric conversion efficiency of 6.06% was achieved for the DSSC with zinc nitrate/urea system.
