PREPARATION MATHOD OF NANO STRUCTURE WITH 2D ARRAY OF TIO2 NANO PARTICLE, NANO STRUCTURE WITH 2DIMENSIONAL ARRAY OF TIO2 NANO PARTICLE MADE BY THE SAME, AND ORGANIC SOLAR CELL INCLUDING THE SAME

摘要

PURPOSE: A manufacturing method of nano-structured which titanium oxide nano-particles are arranged in two dimensions, a nano-structure manufactured by using thereof, and an organic solar cell including thereof are provided to improve energy conversion efficiency of dye-sensitive solar cell . CONSTITUTION: A manufacturing method of nano-structured which titanium oxide nano-particles are arranged in two dimensions comprises next steps: manufacturing micelle solution by dissolving two block copolymers in solvent; manufacturing sol-gel precursor solution containing the titanium oxide; stirring and mixing the micelle solution and sol-gel precursor solution; manufacturing titanium oxide/two layered block copolymer thin film by spin-coating the mixed solution on the substrate; and removing the two layered block copolymers by post-processing the thin film.
