本研究致力於開發以可直接轉換太陽光能為電能之儲能裝置：太陽能再生電池（Solar Regenerated Battery, SRB）。此研究中，成功開發出採用SRB系統之產品雛型裝置(prototype)，並以經離子交換法合成的CuFeO2粉體作為其光陰極之可見光驅動光觸媒。本研究進一步探討兩種氧化還原對(redox couple)對該系統之影響。
經由電化學測試，以銅氨錯合物與氯化銅為SRB系統之氧化還原對，可得出較高之電功率轉換效率，其值為5.01x10-4%。然而，以對苯醌與硫酸銅為SRB系統之氧化還原對，則有較高的光轉換效率，其值為2.7 x10-2 %。

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%.
