Abstract The development of an advanced ultraviolet (UV) photodetector that integrates a polymer‐dispersed cholesteric liquid crystal (PDCLC) with ZnO nanorods (ZNRs) heterostructure is reported. ZNRs are synthesized via hydrothermal method and then spin‐coated PDCLC, resulting in notably enhanced electrical optical performance. Under 365 nm UV illumination at 5 mW cm − 2 10 V, the PDCLC‐coated array achieved high photocurrent density 171 µA , showcasing significant gains over devices without PDCLC. novel ZNRs‐PDCLC demonstrated remarkable responsivity 172.21 mA W −1 external quantum efficiency (EQE) 58.44%, substantial improvement compared to ZNRs‐only (72.27 23.39% EQE) seed layer‐based (14.48 4.8% EQE). This enhancement stems from PDCLC effective sensitization, which promotes charge carrier activation energy band alignment ZnO, dynamic, time‐responsive photodetection. These findings underscore potential heterostructures drive advances high‐performance photodetectors.
