Inorganic-organic hybrid interlayer materials were prepared using aluminum doped ZnO nanoparticles (AZO) and amine-containing perylene diimide (PDIN). By employing this hybrid material as cathode interlayer and BCP as anode interlayer, high-gain polymer photodetectors have been realized. The low-bandgap polymer PB-D-T-TPT photodetector exhibited a significant increase in EQE as large as 25982% (−2.0 V, 360 nm), large responsivity of 77.2 A/W (−2.0 V, 830 nm) and high detectivity of >10¹² Jones (All the specific detectivity in this paper were calculated from EQE and dark current.) over a broad spectral region (300–1700 nm). Using the same hybrid cathode interlayer, the devices based on P3HT and PTII-TT polymers also showed detectivity of >10¹⁵ Jones in 330–640 nm and >10¹² Jones in 320–1600 nm, respectively, further demonstrating a unique ability of AZO:PDIN hybrid interlayer to improve the performance of polymer photodetectors.
