| 摘 要： | 采用阴极电沉积法在导电玻璃基体上制备了TiO2薄膜.运用扫描电子显微镜、X-射线能量散射分析仪和X-射线衍射仪对TiO2薄膜的形貌和结构进行了分析.以N719染料敏化的TiO2薄膜为阳极,0.5 mol/L KI和0.05 mol/L I2的乙氰和乙烯碳酸酯的混合溶液为电解液,碳电极为阴极,组成太阳能电池,通过电流-电压曲线研究了太阳能电池的性能.结果表明:TiO2薄膜的晶型为锐钛矿,其晶粒d平均为28.8 nm.太阳能电池的U开路为0.513 V,J短路为22.8 A/m2,填充因子为0.392,光电转换效率为0.466%.

| Abstract: | The cathodic deposited titanium dioxide(TiO2) thin films were prepared on electronically conductive glass.The morphologies and structures of porous TiO2 thin films were measured and characterized by X-ray diffraction and scanning electron microscopy and energy dispersive X-ray analysis.A dye-sensitized solar cell was consisted of an anodic electrode(porous TiO2 thin films modified by N719 dye),a liquid electrolyte(an acetonitrile/ethylene carbonate mixture containing 0.5 M KI and 0.05 M I2),and a counter el... |
