Study on Dye-Sensitized Solar Cells Made with TiO2 Blend Carbon Powder
摘要
本研究提出二氧化鈦奈米顆粒混合碳粉概念，應用於染料敏化太陽能電池(DSSCs)。本論文對二氧化鈦混合碳粉混摻量比率與天然染料吸光率進行了詳細的調查。當然，太陽能電池特性如：開路電壓、短路電流、填充因子、轉換效率和吸光效率等，也會有系統地調查，並檢測其光學和電特性，進而驗證此二氧化鈦奈米顆粒混合碳粉應用於DSSCs的可行性。結果顯示以ITO玻璃為基板的DSSCs，當C/TiO2的重量比率為1.0時，最佳電性參數值為:開路電壓、短路電流、填充因子、轉換效率分別測得為0.69V、1.062mA、0.22和0.16%。相同地，以ITO-PET為基板的DSSCs，當C/TiO2的重量比率為0.001時，最佳電性參數值: 開路電壓、短路電流、填充因子、轉換效率也分別0.88 V、 1.19mA、0.31、和0.33%。未來，希望此二氧化鈦混合碳粉概念，應用於染料敏化太陽能電池設計，可以提供一個功能強大的工具，來實現更高效率的太陽能電池在進一步。

This study proposed a new design of dye-sensitized solar cells (DSSCs) made with TiO2 nanoparticles blend carbon powder. The parameter of TiO2 blend carbon powder ratio and the absorbance of the nature dyes were investigated for the DSSCs. Certainly, the characterization of solar cells, i.e., open-circuit voltage, short-circuit current density, fill factor, conversion efficiency and absorption efficiency, will be experimentally investigated not only to evaluate the proposed DSSCs, but also to verify the feasibility of the concept. Carbon powder blend TiO2 ratio was experimentally investigated the optical and electric properties of the proposed DSSCs. The results show the C/TiO2 weight ratio of 1.0 for the DSSC utilizing ITO-glass substrate. The maximum electrical parameters: the open-circuit voltage, short-circuit current, fill-factor, and conversion efficiency were measured to be 0.69V, 1.062mA, 0.22, and 0.16 %, respectively. Similarly, the C/TiO2 equals 0.0001 for the ITO-PET substrate. The maximum ones: the open-circuit voltage, short-circuit current, fill-factor, and conversion efficiency were also measured to be 0.88 V, 1.19mA; 0.31; 0.33%, respectively. Eventually, the TiO2 blend carbon powder design of the DSSCs could be provided a powerful tool to achieve the higher efficiency solar cells in the further.
