Enormous researches have been reported to introduce halide perovskite as a high-functional light-harvesting material. Composition and deposition approach have brought the impressive improvement; however, it has not shown a noticeable growth in performance of these materials these days. As a breakthrough, here a nanoimprinting crystallization technique is successfully demonstrated, which enables to fabricate the vertically-grown (VG) halide perovskites photodetectors. Ultimately, the 2-terminal lateral photodetectors based on the VG halide perovskite film shows far enhanced photocurrent, responsivity, and detectivity. We expect that the deposition method presented here help to surpass the technical limit and contribute to further improvement in various halide perovskite-based devices. |
