本研究利用網印版印刷製作TiO2工作電極，並在製作好的TiO2工作電極上，利用光還原法還原銀粒子，添加適當的銀粒子在TiO2工作電極上時，能夠產生表面電漿共振造成局部電場，有利於提升工作電極可見光吸收，使得短路電流、開路電壓上升，整體效率提高。由實驗可得知，在Ag/TiO2還原條件為硝酸銀濃度3 Mm以及光照時間2分鐘時，搭配散射層及四氯化鈦後處理，能夠得到最佳元件。
而在材料分析方面，使用了XRD、FE-SEM、XPS、UV-Vis觀察結晶性、表面形貌、元素組成以及光吸收量，並與未參雜的P25-TiO2進行比較。元件分析方面則是使用EIS、IMVS/IMPS等來量測阻抗及電子傳遞情形。

In this study, the TiO2 working electrode was fabricated by screen printing method, and the silver particles were reduced by photoreduction on the prepared TiO2 working electrode. When the appropriate silver particles were added on the TiO2 working electrode, the surface plasma resonance was happened and generated localized electric field. The electric field is beneficial to increase the visible light absorption of the working electrode, so that the value of short-circuit current and the open circuit voltage rise, and the overall efficiency is improved. It can be seen from the experiment that when the Ag/TiO2 reduction condition is 3 mM of silver nitrate and 2 minutes of illumination time, the best component can be obtained by post-processing with the scattering layer and post-treatment TiCl4.
In terms of material analysis, XRD, FE-SEM, XPS, UV-Vis were used to observe crystallinity, surface morphology, elemental composition, and light absorption, and compared with undoped P25-TiO2. In terms of component analysis, EIS, IMVS/IMPS, etc. are used to measure impedance and electron transfer.
