A TiO2/carbon fibers (CFs) composite electrode is a solar device that converts photon energy to electrochemical energy and stores it in situ. The photoexcited-charge transfer and energy–storage reaction were studied. The results of photoelectrochemical measurements showed that the photoexcited electrons generated in TiO2 moved to CFs via ohmic contact. From a frequency response analysis of the electrochemical impedance, it was found that the electrical energy storage was realized by the formation of lithiated carbons at the CFs side. Since a large time constant was observed in the time variation of photo-emf, it was concluded that the low formation rate of lithiated carbons was one of the causes of small photocharged quantities.
