本研究是以溶膠-凝膠法(Sol-Gel)與旋轉塗佈法(Spin coating)製作TiO2電極，添加不同比例APTMS(SiO2)當TiO2顆粒間的黏結劑，來增加TiO2顆粒間的接觸面積，以降低內電阻，雷射染劑為光敏劑，來增加對光源的吸收與利用；由XRD圖可觀察到晶粒有細化的現象，由SEM圖可觀察到TiO2顆粒接觸面積變大，其中添加5wt%APTMS的TiO2電極，太陽能電池有最佳的光電轉換率達7.3%。

This research is to make TiO2 electrode with Spin coating method and the sol-gel method,changing micro-structure of TiO2 electrode with adding different proportion APTMS.Laser dye is the photosensitive agent, to increase the absorption and use to the light source; we can observe the crystal grain taht thinning phenomena from XRD picture , can observe that TiO2 particle is exposed to the area to change largly from SEM picture, among them add 5wt% APTMS of the TiO2 electrode, the solar cell has the best photoelectric conversion ratio to up to 7.3%.
