Dithienogermole As a Fused Electron Donor in Bulk Heterojunction Solar Cells

Journal of the American Chemical Society, 133(26), 10062–10065.

TL;DR: The synthesis and bulk heterojunction photovoltaic performance of the first dithienogermole (DTG)-containing conjugated polymer is reported, with performance enhancement is a result of a higher short-circuit current and fill factor in the DTG-containing cells, which comes at the cost of a slightly lower open circuit voltage than for the DTS-based cells.
