有機太陽能電池在近幾年積極被開發與研究，具有低成本、製程低溫且、製造簡單、可彎曲、大面積…等優點。在本篇論文中，吾人藉由製造有機太陽能的技術，導入無機半導體材料與加入奈米結構來改善光電轉換效率。
在本篇論文中，將討論薄膜鋁膜(200nm)上製作 AAO(陽極氧化鋁)奈米結構在ITO(氧化銦錫)玻璃上的技術，並且能控制其孔洞大小與品質。在奈米結構方面，使用自備的TiO 溶膠-凝膠(sol-gel)填充在陽極氧化鋁模板內，再將模板去除，形成TiO 奈米柱，透過XRD量測確定其為銳鈦礦(Anatase)，適用於太陽能電池中的授體材料。
在有機太陽能電池中，目前使用P3HT與PCBM的材料，其效率最高。在本論文中，有機太陽能電池中的吸收層利用P3HT與PCBM分別為施體與授體的，在不含低功函數(Ca or LiF)的電極下，光電轉換效率已達1.9％。使用TiO 無機材料一層與P3HT導電高分子一層的復合型太陽能電池，其光電轉換效率已達0.75％。在導入奈米柱後，預期光電轉換效率會提升。但因在製作TiO 奈米柱的均勻性不佳，導致效率只達0.12%，相信在製程最佳化後會有較佳的光電轉換效率。

Organic Solar Cells have been energetically developed and studied in recent years. There are a number of advantages of it, such as low-cost, processing with low temperature, flexible, large area production and easy to fabricate. In this research, the improvement of power conversion efficiency will be done by using technology of generating Organic Solar Cells with the inorganic semiconductor materials and nanostructure.
In this research, it would be discussed that the tech of AAO (Anodic Aluminum oxide) nanostructure fabricated by Aluminum thin film (200nm) on ITO glass, and also could be control the pore size and quality. On the nanostructure, the TiO sol-gel solution fabricated by ourselves would be filled with AAO template. The TiO nanorod would be produced by removing the template of AAO, and by XRD test to confirm that was Anatase and also suitable for the acceptor in Solar Cells.
Until now. The maximum power conversion efficiency of Organic Solar Cells use the material of P3HT and PCBM. In our research, the absorber layer in organic solar cells used P3HT and PCBM as donor and acceptor. The power conversion efficiency had reached to 1.9% when the electrode was without low work function metal (Ca or LiF). Hybrid Solar Cells used n-type inorganic materials and P3HT conducting polymer layer by layer , in which the power conversion efficiency has achieved 0.75%. Then, the power conversion efficiency would increase when the nanostructure was being applied. Because of the inequality of Nanorod during fabricating TiO , causing the efficiency only reached to 0.12%. We believe that the power conversion efficiency would perform better after the optimization of fabrication process.
