NOVELTY - The device has a substrate formed with an anode layer, an anode decorating layer, an active layer, a cathode decorating layer and a cathode layer from a bottom part of the substrate to a top part of the substrate. The cathode layer is made of ferric oxide or lead oxide. The cathode decorating layer is formed with the cathode layer, where the cathode decorating layer is made of natural pigment or pigment derivate. The anode layer is formed with the anode decorating layer. Thickness of the cathode decorating layer is about 0.1-100 nm. The substrate is made of glass or plastic thin film.    USE - Organic/polymer solar battery device.    ADVANTAGE - The device enables increasing organic/polymer solar cell fill factor and energy conversion efficiency.
