Review on Organic–Inorganic Two-Dimensional Perovskite-Based Optoelectronic Devices

Abstract

Organic–inorganic two-dimensional (2D) perovskite is an optoelectronic material, with quantum-well structure and improved moisture stabilities, which has been widely used in various optoelectronic devices recently. In this review, the structure and properties of organic–inorganic 2D perovskite materials are first briefly introduced. After that, according to the different photoelectron coupling mechanisms, the recent progress of typical 2D perovskite-based optoelectronic devices is described in detail: including photodetectors, light-emitting diodes, solar cells, and lasers, as well as some optoelectronic devices (e.g., optical memory and optical synapses). We analyzed the influence of structure, manufacturing process, and material selection on device performance and showed promising progress in different applications. Subsequently, we proposed the possible breakthrough development direction of 2D perovskite-based optoelectronic devices in the coming years. This work points out the way for future progress of 2D perovskite-based optoelectronic devices, which is conducive to further improving device performance and inspiring designs of high-performance organic–inorganic 2D perovskite-based optoelectronic devices.

Lithographic Multicolor Patterning on Hybrid Perovskites for Nano‐Optoelectronic Applications

“…As shown in Figure a, the device channel length is ≈126 nm, which is almost the shortest channel length for all the reported PbI 2 and perovskite‐based photodetectors. [ 37–40 ] The output curves show good contact between the electrodes and the nanosheet (whether being PbI 2 or perovskite shown in Figure 5b,d). For the photodetection performance, much lower light power is required for perovskite than PbI 2 , because the absorption of perovskite is much stronger than PbI 2 .…”

Advances of Commercial and Biological Materials for Electron Transport Layers in Biological Applications

“…The mesoporous layer can not only act as a scaffold, but also increase the contact between the ETL and the perovskite layer and enhance the charge transport efficiency. In the preparation of PSCs, the material and structure of the electron transport layer have a great impact on the performance and stability of the device ( Li et al, 2022 ). Therefore, a great deal of work has been done in this direction.…”

Recent Progress of Polarization‐Sensitive Perovskite Photodetectors

“…They are thus widely studied for detecting X-rays, γ-rays, ultraviolet, visible, and near-infrared light. [66][67][68][69][70][71] Due to their high absorption properties and large atomic numbers, perovskite materials excel in the field of highenergy ray detection. In recent years, the unique role of perovskite materials in polarization detection is gradually emerging.…”
