摘要: 采用简单的离子交换沉积法制备了SnS敏化的纳晶TiO2光阳极。通过SEM、XRD、UV-Vis等手段对光阳极的表面形貌, 晶态结构, 紫外-可见吸收和散射性能进行表征。并分别以聚苯胺和铂为催化剂制备对电极, 以含碘氧化还原电对和硫氧化还原电对溶液为电解质, 组装SnS敏化太阳能电池, 对其光电性能进行研究。通过比较不同光阳极、电解质和对电极的组合, 发现用光阳极为离子交换沉积9次SnS的纳晶TiO2膜, 对电极为聚苯胺不锈钢网压片膜, 电解质为含硫氧化还原电对溶液组装的太阳能电池光电性能最佳, 其短路电流、开路电压、填充因子和光电转换效率分别达到4.59 mA/cm2、0.547 V、0.505和1.27%。

Abstract: A simple method of successive ionic layer adsorption and reaction (SILAR) was employed to prepare SnS sensitized nanocrystallite TiO2 photoanodes. The characteristics of these photoanodes, such as surface morphology, crystal structure, UV-Vis adsorption and diffusion properties, were measured with XRD, TEM, UV-Vis adsorption and diffusion spectra, respectively. The photovoltaic performances of SnS sensitized solar cells with these photoanodes were measured. The effects of counter electrodes with polyaniline or platinum catalyst and liquid electrolytes with iodine or sulfur redox couple on the photovoltaic performance were also studied. The cells assembled with these different components showed different photovoltaic performance. It was found that the cell assembled with the photoanode fabricated by 9 times of SILAR circulation, the counter electrode with polyaniline-stainless steel net, and the liquid electrolyte containing sulfur redox couple showed the highest photovoltaic performance. The short-circuit current density, open-circuit voltage, fill factor, and power conversion efficiency could reach 4.59 mA/cm2, 0.547 V, 0.505 and 1.27%, respectively.
