This article discusses the reasons for the decreased photovoltaic performance of absorber layers where polymers other than P3HT are blended with fullerene multiadducts like ICBA and bis-PCBM. It is found that the reduced performance is due to a mixture of reduced charge generation due to the smaller band offsets and reduced electron mobilities.
