COPOLYMER, ORGANIC SEMICONDUCTOR MATERIAL, ORGANIC ELECTRONIC DEVICE, AND SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a copolymer which can be used as a semiconductor material and is highly stable when prepared as a solution.SOLUTION: The copolymer contains a repeating unit represented by formula (1A) and a repeating unit represented by formula (1B). (In the formulae (1A) and (1B), A is a Group 16 element atom, Qis an atom of C, Si, Ge, Sn, or Pb, and Rto Rare each a hydrocarbon group optionally having a heteroatom.)
