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

摘要

It is an object of the present invention to provide a copolymer that can be used as a semiconductor material and is highly stable in solution. The problem is solved by a copolymer containing a repeating unit having a dioxopyrrole condensed ring skeleton and a repeating unit having a dithieno condensed ring skeleton and also having a specific substituent.
