DETAILED DESCRIPTION - Optoelectronic integrated building material based on dye-sensitized solar cell, comprises electrolyte between photoanode of semiconductor and counter electrode. The photoanode of semiconductor comprises substrate of the photoanode (1), conductive film (2), thin semiconductor film (3), and absorbed photoactivated dye (4). The counter electrode comprises substrate of the counter electrode (7), conductive film, and catalyst layer (6) on the counter electrode. The electrolyte comprises simulation solid state electrolyte or solid electrolyte, and oxidation-reduction compounds. A nanometer crystal semiconductor slurry is directly coated on conductive substrate for building to make thin semiconductor film, the photo-activated dye is absorbed. A catalyst layer of the counter electrode is made of materials which acts catalyst action of the oxidation-reduction action for the electrolyte. The photo-anode of semiconductor is combined with the counter electrode, and the electrolyte is injected in middle, solidified, and adhered, leading lead out of 2 electrodes and connecting them in parallel. A series or a combination of parallel and series forms a large area and makes the optoelectronic building material.
