Description
Summary:In this work, we present a multifunctional device based on a heterojunction active layer formed between the halide perovskite and chalcogenide quantum dots. The device is demonstrated with 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 concept of the heterojunction active layer provides a feasible route to design efficient multifunctional devices in the future. A heterojunction active layer formed between the halide perovskite and chalcogenide quantum dots is employed to construct a multifunctional device. The multifunctional device is demonstrated with an integration of proof‐of‐concept functions, including a light‐emitting diode, an energy harvester, and a photosensor. The concept of the heterojunction active layer provides a feasible route to design efficient multifunctional devices.
