Graphical Abstract

Polymer power: Polymer donors have shown remarkable photovoltaic performance in non-fullerene organic solar cells (OSCs). The molecular design strategies are analyzed in terms of developing suitable polymer donors for non-fullerene acceptors to further improve the power conversion efficiency (PCE) of non-fullerene organic solar cells.

Abstract

Over the past few years, non-fullerene organic solar cells have been a focus of research and their power conversion efficiencies have been improved dramatically from about 6 % to over 14 %. In addition to innovations in non-fullerene acceptors, the ongoing development of polymer donors has contributed significantly to the rapid progress of non-fullerene organic solar cell performance. This Minireview highlights the polymer donors that enable high-performance non-fullerene organic solar cells. We show the impressive photovoltaic devices results achieved by some of important classes of conjugated polymer systems in non-fullerene organic solar cells. We discuss the molecular design strategies as far as developing matching polymer donors for non-fullerene acceptors. We conclude with a brief summary and outlook for advances in donor polymers required for commercialization.
