纳米TiO₂薄膜的制备方法对NPC太阳电池性能的影响

摘要: 采用溶胶凝胶法、粉末涂敷法在导电玻璃上制得纳米TiO₂薄膜.X射线衍射实验表明该薄膜主要是锐钛矿相结构,透射电子显微镜测得薄膜晶粒尺寸为30nm左右,扫描电镜观察了薄膜的表面形貌.分析了这两种方法制得的纳米TiO₂薄膜所组成的染料敏化太阳电池的性能,提出了一种新的制作纳米TiO₂薄膜的方法.

Abstract: Nanocrystalline TiO₂ films were made on ITO glass with sol-gel method and powder-coating method. By X-ray diffraction and TEM, it was shown that the TiO₂ films were mainly anatase structure with a grain size about 30 nm. The surface of TiO₂ films with powder was observed by SEM. The behavior of NPC solar cells composed of the TiO₂ films was analyzed and a method to prepare nanocrystalline TiO₂ films was proposed.
