COPOLYMER CAPABLE OF IMPROVING HOLE MOBILITY INSIDE AN ORGANIC SOLAR CELL PHOTOACTIVE LAYER WHILE COMPRISING 3,6-CARBAZOLE, AN ORGANIC SOLAR CELL USING THE SAME, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A copolymer is provided to have high hole mobility, to have excellent electric performance and photoelectric conversion efficiency, and to be used as a material for an organic material layer of an organic solar cell.;CONSTITUTION: A copolymer comprises a first repeating unit indicated in chemical formula 1 and at least one unit which is different from the first unit. The comprised amount of the first unit is 0-45 mol% based on the total content. A manufacturing method of an organic solar cell comprises: a step of preparing a substrate; a step of forming a first electrode on one region of a backside of a substrate; a step of forming an organic layer which comprises the copolymer, on the first electrode; and a step of forming a second electrode on the organic material layer.;COPYRIGHT KIPO 2013
