摘要

染料敏化太阳能电池(DSSC)具有将太阳光转化为电能的巨大潜力。本文以ZnO:Al薄膜和红火果染料为工作电极，成功制备了DSSC的原型。采用溶胶-凝胶自旋镀膜的方法制备了ZnO:Al薄膜。XRD结果证实，所有ZnO:Al薄膜均为六方结构，晶体尺寸在16 ~ 41 nm之间。SEM分析表明，纳米颗粒粒径在30 ~ 80 nm之间。带隙范围为3.16 ~ 3.40 eV。EIS分析表明，随着温度的升高，电荷传递电阻大大降低。随着后加热温度的升高，DSSC的效率逐渐提高。当后加热温度为600℃时，ZnO:Al的效率最高，为0.398%。

Effect of Post-Heating Temperature on Efficiency of Dye-Sensitized Solar Cell with ZnO:Al Thin Films Prepared by Sol-Gel Spin Coating

Dye-sensitized solar cell (DSSC) has a great potential to convert solar light into electricity. In this article, a prototype of DSSC had been successfully fabricated using ZnO:Al thin film and dye from red dragon fruit as a working electrode. ZnO:Al thin films were prepared by a sol-gel spin coating method with variation of post-heating temperatures. The XRD result confirms that all ZnO:Al thin films have a hexagonal structure with crystal sizes of 16 nm to 41 nm. SEM analysis showed the nanoparticles with particle size of 30 nm to 80 nm. The bandgap ranges from 3.16 eV to 3.40 eV. The EIS analysis reveals that charge transfer resistance greatly decreases with the rise of temperature. The efficiency of DSSC gradually improved with increasing the post-heating temperature. ZnO:Al with a post-heating temperature of 600°C had the highest efficiency of 0.398%.
