摘　　要：柔性染料敏化太阳电池作为具有低生产成本的实用化技术受到高度重视。本文研究以金属钛为基底的纳晶TiO2薄膜电极和以导电涂层聚合物为基底的对电极组成的柔性染料敏化太阳电池。为提高光电转换效率,采用直流低场电泳沉积、直流和脉冲电压下的电化学阳极氧化及丝网印刷,结合高温烧结方法,制备金属钛为基底的纳晶TiO2薄膜电极和TiO2纳米管薄膜电极;用恒电流电化学沉积、化学还原等低温技术制备导电涂层聚合物为基底的载铂对电极和碳对电极。对不同的制备方法及优化技术的机制和特点进行了分析探讨,比较了不同方法制备的纳晶TiO2薄膜电极和对电极的性能。在此基础上,研制全柔太阳电池,最大光电转换效率达到6.74%。Flexible dye-sensitized solar cell has attracted much attention due to its advantages of low cost and easy production. Flexible dye-sensitized solar cell comprised of a nanocrystalline TiO2 film electrode based on Timetal substrate and a counter-electrode based on plastic substrate is investigated. In order to improve the photovohaic performance, the different methods including electrophoretic deposition under low DC field, electrochemical anodization by DC and pulse voltages and screen printing in cooperation with high-temperature sintering were employed to prepare Ti substrate based nanocrystalline TiO2 film electrodes and TiO2 nanotube film electrodes, and low-temperature methods of electrochemical deposition and chemical reduction were used to prepare Pt and carbon counter-electrodes on the plastic substrate. The mechanism and characters of these methods and the techniques of optimization were analyzed and discussed. The performance of the nanocrystalline TiO2 film electrodes and counter-electrodes prepared by different methods were measured and evaluated by their photovoltaic behavior measurements. Flexible dye-sensitized solar cells with Ti substrate based TiO2 photoelectrodes and plastic substrate based Pt counter-electrodes prepared by different methods were fabricated. The maximal light to electricity conversion efficiency of 6.74% was achieved.
