NOVELTY - A solid dye-sensitized nanocrystal microcrystalline silicon composite film solar cell, comprises transparent conductive substrate, dye-sensitized nanocrystal porous membrane, microcrystalline silicon hole transporting layer, and back electrode. The microcrystalline silicon hole transporting layer has energy level matched with the dye. The back electrode is a film comprising aluminum or copper. The dye-sensitized nanocrystal porous membrane is coated on the transparent conductive substrate.    USE - A solid dye-sensitized nanocrystal microcrystalline silicon composite film solar cell.    ADVANTAGE - The solar cell enables dye-sensitized nanocrystal material to be matched with the microcrystalline silicon composite film material, thus it overcomes defects of both poor liquid stability of existing dye-sensitized solar cell and high production cost caused by low preparation rate of microcrystalline silicon film solar cell.    DETAILED DESCRIPTION - Solid dye-sensitized nanocrystal microcrystalline silicon composite film solar cell, comprises transparent conductive substrate, dye-sensitized nanocrystal porous membrane, microcrystalline silicon hole transporting layer, and back electrode. The transparent conductive substrate is a transparent conductive glass substrate or a flexible transparent conductive substrate. The dye-sensitized nanocrystal porous membrane is dye-adsorbed nanocrystal porous membrane. The microcrystalline silicon hole transporting layer has energy level matched with the dye. The back electrode is a film comprising aluminum or copper. The dye-sensitized nanocrystal porous membrane is coated on the transparent conductive substrate. The microcrystalline silicon hole transporting layer is deposited on the dye-sensitized nanocrystal porous membrane to form the solid dye-sensitized nanocrystal microcrystalline silicon composite film. The film comprising aluminum and copper is plated on the solid dye-sensitized nanocrystal microcrystalline silicon composite film to form the back electrode. An INDEPENDENT CLAIM is included for preparation of solid dye-sensitized nanocrystal microcrystalline silicon composite film solar cell.
