摘要
本文采用二氧化钛(P25),粘结剂及溶剂,研磨数小时得到均匀分散的纳米二氧化钛浆料,通过涂布法在FTO导电玻璃衬底上制备了光阳极,并用其组装成染料敏化太阳能电池。经过优化二氧化钛和粘结剂的比例,得到平整、致密、均匀的二氧化钛薄膜。对二氧化钛薄膜进行FTIR、SEM和光学显微镜表征,并对组装电池进行光电性能测试,研究了二氧化钛浆料不同制备条件对太阳能电池性能的影响。结果表明,二氧化钛粉末和粘结剂质量比为4∶3时,制备的二氧化钛浆料稳定性高;涂布厚度为20μm时,电池性能较好。组装的染料敏化太阳能电池在100mW/cm2模拟太阳光照下,光电转换效率达到2.51%。
In this paper, nano-titanium dioxide slurry was prepared through grinding titaniumdioxide （P25）, binder and solvent for several hours. And the slurry was dispersed uniformly. TiO2 thin films were coated on transparent conductive fluorine-doped tin oxide （FTO）substrates and used to assemble dye-sensitized solar cells. To gain smooth, dense, uniform TiO2 thin films, the ratio of titanium dioxide and hinder was optimized. FTIR, SEM and optical microscopy were used to investigate the characterization of the TiO2 thin films. Device characterization was carried out under the solar simulator. The results showed that, when the titanium dioxide powder and binder mass ratio was 4 ： 3, the prepared slurry was highly stable; when the coating thickness was 20μm, device get superior performance. The power conversion efficiency was 2. 51% under the 100 mW/cm^2 solar simulator.
