Operating at room temperature, polymer photodetectors (PDs) with external quantum efficiency approximately 80%, detectivity over 1013 Jones, linear dynamic range over 120 dB, and dark current a few decades of nA/cm2 were demonstrated. All these performance parameters were achieved by combined treatment of active layer with solvent vapor annealing and of polymer PDs with postproduction thermal annealing. These high performance parameters demonstrated that polymer PDs is comparable to or better than inorganic counterparts.
