Abstract
The invention relates to solution-processable, p-type, low-optical gap oligothiophene compounds for use in solar cell application, comprising at least one thiophene-containing group, at least one electron-withdrawing dicyanovinyl or tricyanovinyl group, and at least one electron-donating diphenylaminofluorenyl or N-alkylcarbazole group.
Claims7
A compound for use in solar cell application comprising:
- at least one thiophene-containing group;
- at least one electron-withdrawing group comprises at least one cyanovinyl group;
- and
- at least one electron-donating group;
- wherein the at least one electron-donating group is selected from a group consisting of diphenylaminofluorenyl group, N-alkylcarbazole group, and a mixture thereof.
