In this work, we demonstrate a multifunctional device based on a heterojunction between halide perovskite and CdSe chalcogenide quantum dots. The device is an integration of proof‐of‐concept functions, including a voltage controllable multicolor light‐emitting diode, an efficient energy harvesting device, and a photosensitive detector. The heterojunction concept provides a feasible route to design efficient multifunctional devices in the future.
