POLYMER WITH TRIFLUOROMETHYL BENZIMIDAZOLE THEREOF AND PHOTOVOLTAIC DEVICE USING SAME

摘要

The present invention discloses a polymer compound presented by chemical formula 1. The polymer compound: has an excellent photoelectric efficiency; has an alkyl group introduced thereto and is in the soluble form to be used for a device; may not require a high-temperature heat treatment process; has an excellent processability; and can be used for manufacturing an electric light emitting device on a plastic substrate, which can be bent. The present invention relates to the polymer having a 2H-benzimidazole functional group to which a trifluoromethyl group is introduced, and to a light energy conversion device. In particular, the polymer compound having a trifluoromethyl benzimidazole functional group includes carbazole, benzothiophene, and dithieno pyrrole in a repeat unit, is highly soluble to an organic solvent, and thus has excellent processability.
