“…1(a). [14][15][16][17][18][19][20] Their storage part can be photocharged by carriers transferred from their photovoltaic part.…”

Photo-rechargeable Battery Based on Photo-induced Copper Intercalation into Quasi-One-Dimensional Compound KFeS₂

“…He proposed that it could be charged by photo-induced intercalation of ions into p-type layered semiconductor such as ZeS 2 or ZrSe 2 . Zou et al the reported photo-rechargeable battery using composite electrode made by carbon fiber and TiO 2 [3]. Saito et al prepared the photo-rechargeable cell using three electrodes; energy conversion electrode, charging electrode and counter electrode [4,5].…”

Photoexcited-Charge Transfer and Energy–Storage Reaction of Photorechargeable TiO2/Carbon Fibers Composite Electrodes

“…In order to solve these problems, we have proposed a composite electrode in which the two functions of optoelectric conversion and energy storage are individually assigned to two different materials: photocatalytic and storage materials, respectively. [4][5][6][7][8][9] The photocharging process in the composite electrodes is expected to consist of the following three elementary steps: (1) generation and separation of photoexcited electron-hole pairs within a photocatalyst, (2) transfer of photoexcited electrons (or holes) from the photocatalyst to a storage material, and (3) electrochemical energy-storage reaction caused by transfered electrons (or holes) in the storage material. Several materials have been tested for the composite electrode: TiO 2 or WO 3 was used as a photocatalyst, and a graphite-like carbon, 4) carbon fibers (CFs), 5,6) a conducting polymer 7,8) or Li x MnO 2 9) was used as a storage material.…”

However, the photocharged quantity Q ph was very small about 40 mC g À1 after irradiation of 50 mW cm À2 for one hour.…”
