An isoindigo-based low band gap polymer for efficient polymer solar cells with high photo-voltage
2011 (English)In: CHEMICAL COMMUNICATIONS, ISSN 1359-7345, Vol. 47, no 17, 4908-4910 p.Article in journal (Refereed) Published
A new low band gap polymer (E-g = 1.6 eV) with alternating thiophene and isoindigo units was synthesized and characterized. A PCE of 3.0% and high open-circuit voltage of 0.89 V were realized in polymer solar cells, which demonstrated the promise of isoindigo as an electron deficient unit in the design of donor-acceptor conjugated polymers for polymer solar cells.
