Abstract

The organic material with numerous technological advantages and desirable properties promotes the development of highperformance organic photodetectors (OPDs), possessing wide applications in various fields. The photomultiplication (PM) type OPDs with sandwich structure of ITO/PEDOT: PSS/PBDB-T: PC71BM (mass ratio, 50:1)/Al are successfully demonstrated. The effect of methanol treatment (MT) on the performance of PM type OPDs was investigated in this work. The dark current of PM type OPDs with MT is higher than that without MT under working voltage, and the external quantum efficiency (EQE), responsivity and specific detectivity of PM type OPDs is less than that without MT. The champion EQE value of OPDs with or without MT at -40 V approaches 280% or 330% under 680 nm light illumination, respectively. The PM effect can be ascribed to the hole tunneling injection assisted by interfacial band bending. This work confirms the unavailability of MT on improving the performance of PM type OPDs, providing new insight into achieving excellent performance PM type OPDs.
