| 摘 要： | 采用水热法制备TiO2纳米浆,与P25粒子和TiO2散射大粒子混合制成级配浆料。将所得的浆料涂敷在铟掺杂氧化锡-聚苯二甲酸乙二醇酯导电聚合物基板上,并在120～150℃进行热处理制成光阳极薄膜。利用溅射法制备Pt对电极,将其组装成柔性的染料敏化太阳能电池(dye-sensitized solar cell,DSC)。研究了对电极溅射时间、TiO2薄膜热处理温度、膜厚以及级配浆料中的酸添加量对电池光电性能的影响。结果表明:当对电极Pt溅射时间为30s,TiO2薄膜热处理温度为150℃,膜厚为10.5μm,浆料添加0.05mol/LHNO3时,柔性DSC的光电性能最好,光电转换效率可达4.05%。

| Abstract: | A binder-free paste with a graded structure, which was composed of titania (TiO_2) nano-particles synthesized by hydrothermal method, titania particles named P25 and scattering large particles, was prepared. The TiO_2 photoanode film was prepared on a conductive indium-tin oxide -coated polyethylene naphthalate plastic sheet in a temperature range of 120-150 ℃ by a doctor-blade method. The Pt counter electrode was prepared by an ion sputtering method. The effects of sputtering time of Pt counter electrode, heat-treatment temperature, thickness of TiO_2 film and the acid content of the paste on the photovoltaic performance of the flexible dye-sensitized solar cell (DSC) fabricated from the above materials were discussed. The results show that the flexible DSC has the highest light-to-energy conversion efficiency of 4.05% when the Pt sputtering time is 30 s, the acid content is 0.05 mol/L, the heat-treatment temperature is 150 ℃ and the film thickness is 10.5 μm. |
