Solution-processed, organic solar cells constitute a lightweight, flexible, and cheaply manufactured source of electricity, typically comprising a polymeric donor and a fullerene acceptor. The polymeric nature of the donor tends to complicate its synthesis, purification and reproducibility. Here, a non-polymeric donor material which yields desirable morphologies and high efficiencies (4.4 ± 0.4%) when solution-processed with a fullerene acceptor is reported.
