Abstract

The photodetectors generally works as the significant unit in intelligent optoelectronic systems, converting optical signal into electrical signal. The photomultiplication (PM) type polymer photodetectors (PPDs) were successfully demonstrated based on sandwich structure of ITO/PEDOT:PSS/PBDB-T:polymer acceptor (mass ratio, 100:3)/Al. The performance of PM type PPDs were enhanced by solvent additive 1-chloronaphthalene (CN). The EQE value of PM type PPDs with CN under -15 volts bias approaches 860% and 600%, and is better than EQE values of 300% and 240% in PM type PPDs without CN under 350 nm and 670 nm light illumination, respectively, which confirms the effectiveness of solvent additives CN on improving the performance of PM type PPDs. The PM phenomenon can be ascribed to the hole tunneling injection assisted by interfacial band bending. This paper provides new insight into realizing excellent performance PM type PPDs.
