NOVELTY - The decoration film comprises a flexible substrate (110), a first electrode layer (120) disposed on the flexible substrate, a polymer photoelectric conversion layer (130) disposed on the first electrode layer, a second electrode layer (140) disposed on the polymer photoelectric conversion layer, and an adhesion layer (150) disposed on the second electrode layer such that the first electrode layer, the polymer photoelectric conversion layer, and the second electrode layer are located between the adhesion layer and the flexible substrate.    USE - The decoration film is useful in a device such as a housing of an electric device comprising a cell phone, a digital camera, a note book, a digital photo frame, a display, a personal digital assistant, a media player and a global positioning system (all claimed).    ADVANTAGE - The decoration film is capable of providing a photoelectric conversion function hence it is compatible for the flexibility of the decoration device, can be manufactured in a simple manner with different shapes, and allows to rapidly and easily form the decorations on the surface of the plastic housing with consistent thickness.    DETAILED DESCRIPTION - The decoration film comprises a flexible substrate (110), a first electrode layer (120) disposed on the flexible substrate, a polymer photoelectric conversion layer (130) disposed on the first electrode layer, a second electrode layer (140) disposed on the polymer photoelectric conversion layer, and an adhesion layer (150) disposed on the second electrode layer such that the first electrode layer, the polymer photoelectric conversion layer, and the second electrode layer are located between the adhesion layer and the flexible substrate. The polymer photoelectric conversion layer is located between the first and second electrode layers, where one of the first electrode layer and the second electrode layer is a transparent conductive layer. A material of the polymer photoelectric conversion layer comprises a p-type semiconductor polymer and an n-type semiconductor polymer. The carbon nanotubes comprise single wall carbon nanotubes and/or multi wall carbon nanotubes. The semiconductor nanoparticles comprise titanium oxide nanoparticles, cadmium selenide nanoparticles and/or cadmium sulfide nanoparticles. First and second conductive patterns penetrate through the adhesion layer, where the first conductive pattern contacts a side of the first electrode layer away from the flexible substrate and the second conductive pattern contacts a side of the second electrode layer away from the flexible substrate. A pattern layer is disposed between the flexible substrate and the adhesion layer and located at a side of the polymer photoelectric conversion layer adjacent to the transparent conductive layer. A releasing layer is disposed between the flexible substrate and the first electrode layer. A protection layer is disposed between the releasing layer and the first electrode layer. The releasing layer and the protection layer have a rough surface away from the first electrode layer. The second conductive pattern further penetrates through the first electrode layer and the polymer photoelectric conversion layer while the second conductive pattern is electrically isolated from the first electrode layer.
