NOVELTY - The panel (1) has a non-touch zone (13) located immediately around a touch zone (11). The touch zone is provided with a photovoltaic conversion layer (112) including an upper side attached to a lower side of a transparent substrate (111) of the touch zone. A touch electrode layer (113) of the touch zone is formed on an upper side of another transparent substrate (117) of the touch zone to be attached to a lower side of the photovoltaic conversion layer. The photovoltaic conversion layer includes a transparent electrode layer (1121) attached to the lower side of the transparent substrate.    USE - Touch panel for use in a general portable electronic device.    ADVANTAGE - The photovoltaic conversion layer includes increased light-absorption areas to convert more light into more electric current for the panel, so that the panel can have effectively extended standby and operation time. The panel designed with photovoltaic conversion function ensures reduced thickness. The panel utilizes an anti-reflective layer to enable reduced light reflection and increased light transmissivity of the panel.    DETAILED DESCRIPTION - The photovoltaic conversion layer is a thin-film solar cell layer selected from group consisting of an amorphous silicon thin-film solar cell layer, gallium arsenide thin-film solar cell layer, cadmium telluride thin-film solar cell layer, copper indium gallium selenide thin-film solar cell layer and a dye-sensitized solar cell layer. The latter transparent substrate is made of material selected from a group consisting of polyethylene terephthalate, polycarbonate, polyethylene, PVC, polypropylene, polystyrene, polymethylmethacrylate, cyclo olefin copolymer and glass.
