Abstract
Organic photovoltaic (OPV) cells represent an exciting class of renewable energy technology; they are lightweight and flexible, and have a low production cost. Over the last two decades, the efficiency of these devices has improved significantly, in particular through the development of solution-processed bulk heterojunction (BHJ) OPV cells. While fullerenes have been the most intensively studied acceptor materials in BHJ OPVs, research is currently underway in several groups investigating non-fullerene molecular acceptors. In this review, initial breakthroughs and recent progress in the development of polymer donor-polymer acceptor (all-polymer) BHJ OPVs are highlighted.
