The invention discloses a solid dye-sensitized nanocrystal/microcrystal silicon composite film solar cell and a preparation method thereof, and relates to a special semiconductor device for converting light energy into electric energy. The solid dye-sensitized nanocrystal/microcrystal silicon composite film solar cell is composed of a transparent conducting substrate, a dye-sensitized nanocrystalporous film, a porous membrane, a microcrystal silicon hole transport layer and a back electrode, wherein the dye-sensitized nanocrystal porous film is coated on the transparent conducting substrate;the microcrystal silicon hole transport layer is settled on the dye-sensitized nanocrystal porous film to form the solid dye-sensitized nanocrystal/microcrystal silicon porous film; and an aluminum or copper film is plated on the solid dye-sensitized nanocrystal/microcrystal silicon porous film to form the back electrode. In the invention, the dye-sensitized nanocrystal and the microcrystal silicon composite film are match
