摘要
It is demonstrated that squaraine:PC70BM blends can result in solar cells with high efficiency and fill factor when the nano-structure scale is increased to lead to conduction of photogenerated carriers to the electrodes. Morphological control occurs by a combination of thermal and solvent annealing of these small molecule, solution-processed bulk heterojunction cells. Peak efficiencies of a population of devices is 5.2% at fill factors of 0.5 are achieved under optimized conditions. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
