Abstract
New dithienogermole-based conjugated polymers were synthesized by the Stille coupling reactions of distannyldithienogermole and dibromoarene, and their photovoltaic properties were studied. These polymers possess low band gaps with broad absorptions covering the 400-800Â nm range, and exhibit good film forming properties. Bulk hetero-junction solar cells prepared from blends of these polymers with PC70BM exhibit high power conversion efficiency up to 2.38%.
