| 中文摘要 | 本研究開發以Ti-6wt%Nb合金板經H2O2預處理後形成多孔鈦鈮氧化物表面做為高效能染敏太陽能電池光陽極。經合金化的多孔氧化物不僅具有與網印TiO2顆粒接觸的高表面積，Nb亦被證實擴散至TiO2燒結體。表面多孔氧化物之採用可增加DSSC光電轉換效率達22%，Nb合金化可更進一步提升效率15.2%至18.3%。 |
| 英文摘要 | A native mesoporous titanium-niobium oxides layer on a Ti-6wt%Nb alloy sheet surface prepared through H2O2 pretreatment was successfully developed as an efficient photoanode for a dye-sensitized cell (DCCS) in this study. This alloyed mesoporous structure not only provided an increased surface area in contact with screen-printed TiO2nanoparticles but also enabled Nb alloying in sintered nanoparticle deposits. Energy conversion efficiency improvement of DSSCs can be increased up to 22% using H2O2 pretreatments with a proper post annealing, and the mesoporous Ti–Nb photoanodes enhanced conversion efficiency by 15.2% to 18.3%, compared with unalloyed structures. |
