Abstract
Improved electron acceptor materials for organic photovoltaic (OPV) cells are provided. More specifically, electron acceptor materials for OPVs can include vinylimide, vinylthioimide, alkynylimide and/or alkynylthioimide moieties. Experimental work with members of this class of material has demonstrated record solar cell power conversion efficiency (3.36%) for non-fullerene acceptors.
