NOVELTY - Metal flexible dye-sensitized solar cell is equipped with an aluminum doped zinc oxide glass (203) electrode and a coated metallic board (211). The coated metallic board comprises a former barrier layer (204) with carbon thin film, which is made of silver. A polymer plastic substrate (201) comprises polyethylene terephthalate, polyethylene naphthalate or polyethersulfone, which is deposited on barrier layer using radio frequency magnetron sputtering. Aluminum oxide is coated on the upper portion of an electrode substrate (200). A metallic layer (213) is coated on the metallic board.    USE - Metal flexible dye-sensitized solar cell.    ADVANTAGE - The metal flexible dye-sensitized solar cell is eco-friendly, has improved photoelectric conversion efficiency, and reduced the transmitted leakage phenomenon.    DETAILED DESCRIPTION - Metal flexible dye-sensitized solar cell is equipped with an aluminum doped zinc oxide glass (203) electrode and a coated metallic board (211). The coated metallic board comprises a former barrier layer (204) with carbon thin film, which is made of silver. A polymer plastic substrate (201) comprises polyethylene terephthalate, polyethylene naphthalate or polyethersulfone, which is deposited on barrier layer using radio frequency magnetron sputtering. Aluminum oxide is coated on the upper portion of an electrode substrate (200). A metallic layer (213) is coated on the metallic board, where metallic layer is made of the stainless steel and titanium dioxide. The surface of aluminum doped zinc oxide glass electrode is sealed with ethylene vinyl acetate. The latter barrier layer is coated on the upper portion of the metallic layer using titanium dioxide or silicon dioxide. The upper portion of latter barrier layer is coated by metallic layer. A dye layer is coated on the upper portion of titanium dioxide layer, where the dye is organic dye and inorganic pigment. Aluminum doped zinc oxide glass is etched in hydrochloric acid aqueous solution (1%) for 5~30 seconds. An INDEPENDENT CLAIM is included for a method for preparing metal flexible dye-sensitized solar cell.
