ORGANIC SEMICONDUCTOR POLYMER, COMPOSITION FOR ORGANIC SEMICONDUCTOR MATERIAL, AND PHOTOVOLTAIC CELL

摘要

A polymer, a photovoltaic cell, a composition for an organic semiconductor material, and an organic semiconductor polymer having a structural unit represented by general formula (I). In the formula, X represents Si, S, or O; R1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an aromatic heteroring group, or an oxygen atom; and p represents 0, 1 or 2. The bond between X and R1 is a single bond when X represents Si and is a double bond when X represents S. When X represents O, p represents 0.
