Abstract
This invention relates to a formulation comprising p-type and n-type organic semiconductors and a solvent mixture comprising an aromatic hydrocarbon substituted with one or more substituents selected from alkyl and alkoxy groups and a unsubstituted or substituted benzothiazole, for example 2-methylbenzothiazole. The formulation may be used to form the photoactive layer () of a photosensitive organic electronic device, for example an organic photodetector, comprising an anode () a cathode () and the photoactive layer between the anode and the cathode.
