摘要
利用钛酸四丁酯水解反应,结合溶胶-凝胶与水热处理法制备了TiO2纳米团聚体。以该团聚体制备染料敏化太阳电池的光阳极,不但可以保持纳米粉体高比表面积的优点,同时可以提高对太阳光的散射率,简化电池制备工艺。本文研究了水解pH值对粉体物理性质、电池效率的影响规律。结果表明,水解的pH值对TiO2纳米粒子的尺寸、分布以及染料敏化太阳电池光阳极的显微形貌、电池光电特性都有很大影响。当pH值为1时,制备的电池效率最高达到5.77%(Jsc=15.04 mA/cm2,Voc=0.73 V,FF=0.53)。
Nano-TiO2 clusters were prepared by Sol-gel and hydrothermal method including hydrolyzing tetrabutyl titanate in acetic acid solutions.Such nano-TiO2 clusters were applied as dye-sensitized solar cells photo-anode which not only represents the good properties of high surface area of nano-particles but also enhances the light-scattering effect and simplifies the solar cells fabrication process.The effect of pH value on particle physical properties and the solar cell efficiency was investigated in this pape...
