Influence of thermal annealing of Ag NWs/AZO composite films on behavior of Ag NWs/AZO-P3HT photodetectors

Solution-processed silver nanowires (Ag NWs)/AZO composite films were deposited on indium-free transparent conductive layers to yield hybrid photo-diodes. In this study, high-quality Ag NWs/AZO films were prepared by simple and controllable annealing process at 340 °C under nitrogen atmosphere instead of low annealing temperature used previously. P-type polymer poly-3-hexylthiophene-2,5 -diyl (P3HT) was then spin-coated on Ag NWs/AZO top to form...
