摘要：本文介紹了染料敏化太陽能電池中TiO2光陽極的研究與應用現狀，對TiO2光陽極的制備方法進行了綜述，論述了以PS膠體晶體為模板，TiCl4為鈦源，通過溶膠-凝膠法和浸漬滲透法對TiO2前驅體填充至膠體晶體間隙，再利用煅燒去除膠體晶體模板，得到三維有序大孔TiO2薄膜。通過掃描電鏡(SEM)、透射電鏡(TEM)對PS膠體晶體表面結構進行了表征，并對最終的TiO2薄膜也進行了SEM表征和紅外光譜檢測。組裝的染料敏化太陽能電池在100 mW/cm2模擬太陽光照下，光電轉換效率達到4.44 %。

Abstract:This article describes the TiO2 photo-anode dye-sensitized solar cell research and application, reviewed and discussed the preparation method of TiO2 photo-anode PS colloidal crystals as templates, TiCl4, titanium source, by a Sol-gel technique andimpregnated penetration of TiO2 precursor filled to the clearance of colloidal crystals, re-use calcined to remove the colloidal crystal template, the three-dimensional ordered macroporous TiO2 film. By scanning electron microscopy (SEM), transmission electron microscopy (TEM) to characterize the surface structure of PS colloidal crystals, the TiO2 film and the final SEM characterization and Infrared Spectroscopy. The power conversion efficiency was 4.44% under the 100 mW/cm2  solar simulator.
