Organic photovoltaic donor polymer containing alkylidenefluorene and organic solar cell device using the same

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic photoelectric conversion polymer containing an alkylidene fluorene and an organic photovoltaic device (OPV device) using the same, and more particularly, (n-type molecular) and alkylidene fluorene as a main chain, the oxidation stability and planarity of the polymer are increased, and the transfer characteristics of holes are enhanced by intermolecular interaction, thereby exhibiting high efficiency photoelectric conversion characteristics The organic photoelectric conversion polymer and the polymer and PCBM (Phenyl-C61-butyric acid methyl ester; PC₆₁BM or phenyl C71-butyric acid methyl ester; PC₇₁The present invention relates to a bulk heterojunction type organic photoelectric conversion device using a photonic crystal (BM).;
