摘要: Soluble, electroactive derivatives based upon dibenzo[b,def]chrysene are introduced. These compounds do not chemically react with fullerenes, enabling the preparation of solution-processed solar cells on small molecule blends. Device power conversion efficiencies 2.25% described and a correlation between processing conditions, film morphology, device is demonstrated.
