摘要
All solution-processed large-area patterned flexible photodetectors were successfully fabricated by utilizing small-molecule organic semiconductor/polymer hybrid film as an active layer and patterned printed Ag electrodes. The large-area hybrid film could be fabricated by a direct solution-process self-assembly method and had a wide absorption spectrum and improved charge transport ability, resulting in high photoresponsivity. Moreover, the device displayed fast response time, high stability and broadband spectral response. Importantly, the device exhibited high flexibility, good folding strength and electrical stability on shafts with different curvature radiuses and after bending. Even after 500 bending cycles, the device still showed good photodetector and photoswitching properties. The facile low-cost large-area fabrication process and excellent performance gives potential applications in large-scale flexible electronic devices.
