Vertically aligned ZnO nanorods were grown using a simple aqueous solution (AS) method as a function of growth temperature. The correlation between the morphology of ZNR films and the optoelectronic properties of the ZNR/VOPc hybrid devices was investigated. The results show that the hybrid diodes with ZNR films grown at 120 °C offer the best optoelectronic properties. The higher photocurrent responsivity, R<inf>ph,</inf> (16.28 A/W) was achieved for devices with ZNR films grown at 120 °C. This value is 25 times higher than the R<inf>ph</inf> value obtained for the devices made with ZnO nanoparticle films that were reported earlier. © 2019Aluminum compoundsCarrier mobilityCharge transferDiodesII-VI semiconductorsMorphologyNanorodsThin filmsVanadium compoundsZinc oxideZnO nanoparticlesHybrid photodiodesImpedance spectroscopyOptoelectronic propertiesResponsivityVanadyl phthalocyanineVertically alignedZinc oxide nanorodsZnO nanoparticle filmsOxide films
