With the increasing demand for wearable, portable, and implantable optoelectronic devices, flexible photodetectors have become hotspots of scientific pursuit. In this work, a heterostructure photodetector was fabricated through combination perovskite CsCu2I3 nanorods ZnO quantum dots by facile solution method. The combines good bending resistance, low dark current, excellent photoelectric conversion efficiency with high electron mobility dots; NRs act as light compensating material hole collector, while serves an transport channel. This results in stronger UV absorption reduced influence visible light, achieving ultraviolet-to-visible rejection ratios 8 × 102. exhibits superior performance visible-blind ultraviolet region, boasting on–off ratio 102, tenfold increase compared to single-component NR photodetectors. Its responsivity specific detectivity, at 1.62 A/W 4.13 1011 Jones, respectively, outperform 40 23 times surpass 102 times. response time is about 50% shorter than that also shows flexibility environmental mechanical stability after series sharp bends. indicate CsCu2I3/ZnO provides promising alternative high-performance optoelectronics.
