A low-cost mixed fullerene acceptor blend for printed electronics†
Abstract
The synthesis and performance of a cost-effective mixed fullerene at the 100+ g scale with a reaction yield of 85% is demonstrated. The cost to convert a fullerene such as C60 into the mixed acceptor blend is less than $1 g−1. The photovoltaic performance of the mixed acceptor is demonstrated in both small scale and roll-to-roll printed devices.
