摘要

Organic photovoltaics (OPVs) based on conjugated polymers are promising for low cost, scalable solar energy conversion. Much progress has been made in the field of bulk heterojuction (BHJ) OPVs with polymer/fullerene derivative systems in the last decade, already reporting power conversion efficiencies (PCEs) approaching 10 %. In contrast, the performance of polymer/polymer (all-polymer) solar cells comprised of both donor and acceptor polymers and free of fullerenes, has been reported with very low efficiency. The development of highly efficient all-polymer solar cells has lagged significantly behind polymer/fullerene systems despite their potential advantages including tunable electronic structure, enhanced absorption coefficients, increased photovoltage, superior thermal/mechanical robustness, and facile control of solution viscosity for industrial coating process.
