在本論文研究期間，曾經嘗試以溶膠凝膠法製備鋁、錫共摻至氧化鋅薄膜之研究， 企圖尋求經濟、無毒之氧化鋅透明導電薄膜，以便取代論文中第三部分所使用的氧化銦錫玻璃( I TO) ，製作一對環境友善之“全氧化鋅”染料敏化太陽能電池。研究結果雖然在透光度上已與I TO 玻璃相近，但在導電性上，與I TO玻璃仍有差距，為使論文內容精簡、結構嚴謹，只好將此部分之結果呈現於附錄中。;Nanorods of zinc oxide (ZnO) suitable for making of photodetectors and dye-sensitized solar cell (DSSC) were prepared by means of chemical bath deposition (CBD) method in this work. For making photodetectors, the ZnO nanorods were deposited on silicon substrate; whereas for making of photovoltaics, the ZnO nanorods were deposited on the glass of indium-tin oxide (ITO). On the purpose to develop the nanorods with high aspect ratio, large specific surface area and good alignment of matrices suitable for light trapping and harvesting, the conditions of the CBD should be carefully controlled. This work comprised three parts: the first one focused the conditions to prepare ZnO nanorods those are qualified enough for making the photodetectors and photovoltaics. The second is the preparation of photodetectors from a concept of the heterojunction between an n-type ZnO and the p-type Si based, and the photodetection was also demonstrated to check the detectors. The third part was to construct the ZnO-based photovoltaic devices, a simple Grätzel type solar cell (DSSC), and the demonstration to test their performance. The performance of the proto-type photodetectors and photovoltaics indicated that ZnO nanorods prepared by CBD in this work were satisfactory for their use in the devices.
Another interest was to prepare the transparent conductive oxide (TCO) films of ZnO (doped with aluminium and tin) by sol-gel dip-coating process. This was a trial to replace ITO-coating on the glass for a concept with overall oxide-devices on the base of simple ZnO. Unfortunately, even the optical transparency was competitive; the electrical conductivity of the Al, Sn-doped ZnO films was inferior to ITO. Therefore, the preparation and characterization of Al, Sn-doped ZnO films were put in the appendix.
