| Summary: | 碩士 === 國立臺灣科技大學 === 材料科學與工程系 === 102 === A novel solar-regenerated battery, SRB, capable of converting solar energy to electricity and storing it, was sucessfully developed in this work. The prototype of SRB system in the present research, where visble-light-driven photocatalyst CuFeO2 played a role of photocathode, stably worked under illumination. Besides, the influence of two redox couples, Cu(NH3)4Cl2/Cu(NH3)2Cl and quinone/hydroquinone, on the electrochemical performance of the SRB was investigated.
The experimental results showed that a relatively high power efficiency, 5.01 x10-4%, was obtained as Cu(NH3)4Cl2/Cu(NH3)2Cl served as a redox couple for the SRB although the SRB system in which quinone/hydroquinone was the redox couple displayed a relatively high photon-to-current conversion efficiency, 2.7 x10-2%.
