NOVELTY - The panel has a photoelectric material layer formed with RGB colors, where the photoelectric material layer comprises red units, green units and blue units that are arranged corresponding to pixel arrays in a display unit. The red units, the green units and the blue units are made of photoelectric active material. A black matrix is made of photoelectric active material and conductive material that is coated with an insulating adhesive. A hole transmission layer (412) is provided between a transparent substrate layer and the photoelectric material layer.    USE - Solar cell panel for being integrated on a surface of a display unit such as an LCD unit e.g. transmissive LCD unit, a semi-transmissive/semi-reflective LCD unit and a reflective LCD unit, anelectrophoresis type display unit, an interference and modulation type (IMOD) display unit, an electrical soakage type display unit, a plasma display unit, an LED display unit, an OLED display unit and a CRT display unit, of a display device (all claimed) in portable devices such as laptops, tablets and mobile phones. Can also be used for an outside electronic hoarding.    ADVANTAGE - The panel utilizes photoelectric active material layer with RGB colors as a conventional color filter, so that the obtained solar cell panel can function the color filter so s to eliminate a color filter layer in the display device, thus simplifying process of producing the display device integrated with the solar cell panel and saving cost, and hence improving productivity. The solar cell layer and the display panel layer are separately produced since the solar cell panel is located on a surface of the display unit, so that ratio of defective products in production can be effectively reduced. The black matrix and red, blue and green units are made of photoelectric active material to allow increase of an effective area of the photoelectric active material layer, thus effectively increasing of photoelectric conversion capability of the panel. The panel obtains different output voltages and currents by optimizing design of a solar cell circuit according to actual requirements so as to satisfy requirements of different terminal application. The panel can convert a portion of absorbed unnecessary backlight and ambient light entered into the display device from outside into electric power while functioning as a filter for replacing a conventional color filter in an effective manner, thus increasing capability of solar cell of the portable device, and hence decreasing weight of the device and obtaining comparable or higher use duration.
