ABSTRACT:
This disclosure relates to a polymer that includes a first comonomer repeat unit containing a benzothiadiazole moiety, a thiophene oxide moiety, a cyclopentadithiophene oxide moiety, a thiadiazoloquinoxaline moiety, a benzoisothiazole moiety, a benzothiazole moiety, a thienothiophene moiety, a thienothiophene oxide moiety, a dithienothiophene moiety, a dithienothiophene oxide moiety, or a tetrahydroisoindole moiety. The polymer can be used as a photoactive material in a photovoltaic cell. This disclosure also relates to such photovoltaic cells, as well as modules containing such photovoltaic cells.
