Abstract:
1. A method of manufacturing a solar cell comprising the steps of: a) applying slurry containing TiO b) forming Sb c) applying a solution containing P3HT [poly(3-hexylthiophene)] which is an organic photovoltaic material to the porous electron transporting layer formed with the inorganic semiconductor type sensitizer to form a hole transporting layer, wherein the pores of the porous electron transporting layer are filled with the P3HT, and the applied P3HT and the inorganic semiconductor type sensitizer contact each other, and wherein the hole transporting layer has a LUMO level higher than an Ec level which is the lowest energy level of the conduction band of the inorganic semiconductor type sensitizer, so that the photoelectron generated in the hole transporting layer spontaneously moves to the inorganic semiconductor type sensitizer.
