Abstract

So-called organic photovoltaic devices have seen certified power conversion efficiencies increase from 2.5% in 2001[1] to 8.3% in 2011[2]. Close inspection of the strategies employed to realize this impressive improvement in performance reveal a common approach of synthesizing new donor polymers and molecules, fullerene acceptors and, in some cases, new device architectures. It is questionable as to whether this approach will result in a similar four-fold level of improvement over the next ten years, and it is this question that motivates the work described here.
