Abstract

The invention discloses a composite thin film solar cell taking a microcrystalline silicon layer as an incident layer and a preparation method thereof, which relate to a special semiconductor device applied to the conversion of luminous energy into electric energy. The composite thin film solar cell consists of a transparent conductive layer, a microcrystalline silicon hole transmission layer, a dye-sensitized nanocrystalline porous film and a conductive substrate, wherein the dye-sensitized nanocrystalline porous film is coated on the conductive substrate, the microcrystalline silicon hole transmission layer is deposited on the dye-sensitized nanocrystalline porous film to form a solid-state dye-sensitized nanocrystalline microcrystalline silicon composite thin film, and the transparent conductive layer is deposited on the microcrystalline silicon hole transmission layer so as to form the composite thin film solar cell taking the microcrystalline silicon layer as the incident layer. A dye-sensitized nanocrystalline material and the microcrystalline silicon composite thin film material are directly prepared on the conductive substrate, so the composite thin film solar cell and the preparation method thereof overcome the shortcomings of dependence of a dye-sensitized solar cell on transparent conductive glass, low preparation rate and high preparation cost of the microcrystalline silicon thin film solar cell, and the low liquid stability of the conventional dye-sensitized solar cell in the prior art.

Description

technical field [0001] The technical solution of the invention relates to a semiconductor device specially suitable for converting light energy into electric energy, specifically a composite thin-film solar cell with a microcrystalline silicon layer as an incident layer and a preparation method thereof. Background technique [0002] The current dye-sensitized solar cell (Dye-sensitized Solar Cell, referred to as DSSC) has achieved a photoelectric conversion efficiency close to that of silicon cells at one-tenth of the cost of silicon cells, and has great application prospects. Traditional DSSCs are mainly composed of transparent conductive glass, porous titanium dioxide film, dye sensitizer, solution or solid electrolyte, and counter electrode. For example, CN201478130U discloses a new structure of a solid titanium dioxide dye-sensitized thin-film solar cell, CN201302932 an electrode structure of a dye-sensitized solar cell, and CN101740238A a dye-sensitized solar cell and i...
