Photo-rechargeable battery is a device that converts photo-energy to e
lectrochemical energy and stores it. Many electrode materials have bee
n studied for this device. These materials are mainly layered semicond
ucting compounds. We synthesized a new layered compound CuFeTe2. In th
is study, CuFeTe2 was tested for photo-rechargeable battery electrode.
As a result, we revealed that CuFeTe2 was charged by a Xe lamp irradi
ation. Further a model for this photo-charging mechanism is proposed.
