Bodipy-backboned polymers as electron donor in bulk heterojunction solar cells.

Bodipy-based polymers, which possess a high absorption coefficient with a bandgap of approximately 1.6 eV, have been used as electron donor in solution-processed bulk heterojunction (BHJ) solar cells containing PCBM as acceptor. A power conversion efficiency (PCE) of approximately 2% has been achieved with V(oc) of approximately 0.8 eV and J(sc) of approximately 4.8 mA cm(-2).
