Organic/Inorganic Metal Halide Perovskite Optoelectronic Devices beyond Solar Cells

Abstract

Investigations of organic–inorganic metal halide perovskite materials have attracted extensive attention due to their excellent properties including bandgap tunability, long charge diffusion length, and outstanding optoelectronic merits. Organic–inorganic metal halide perovskites are demonstrated to be promising materials in a variety of optoelectronic applications including photodetection, energy harvesting, and light‐emitting devices. As perovskite solar cells are well studied in literature, here, the recent developments of organic–inorganic metal halide perovskite materials in optoelectronic devices beyond solar cells are summarized. The preparation of organic–inorganic metal halide perovskite films is introduced. Applications of organic–inorganic metal halide perovskite materials in light‐emitting diodes, photodetectors, and lasers are then highlighted. Finally, the recent advances in these optoelectronic applications based on organic–inorganic metal halide materials are summarized and the future perspectives are discussed.

All-Perovskite Photodetector with Fast Response

“…The photo-FETs have been explored extensively by many groups [5][6][7][8][9][10][11]. Generally, to achieve low dark current, a thin active layer is favorable, which renders as depletion layer and can be tuned readily by electric field applied from a gate electrode.…”

Construction of Large‐Area Ultrathin Conductive Metal–Organic Framework Films through Vapor‐Induced Conversion

“…[6,13,14,[17][18][19][20] Nevertheless, some of the traditional but practical devices (e.g., field effect transistor (FET), light emitting diode (LED), light emitting transistor (LET), and so on) based on MOGA still remain at a very naive stage with almost no report. [1][2][3][4][5] The key technology about fabrication of large-area films with controllable thickness and orientation suppresses the development of devices, so the study on construction strategy is becoming extremely urgent. [21] While the opportunities to fabricate MOGA films have been explored in a few cases to date, there are still a lot of challenges to overcome: thin film quality, growth mechanism, controlling the defects, improving the stability, enhancing the electrical conductivity, and effectively manipulating charge carrier.…”

“…Owing to the novel electronic, optical, and mechanical properties, 2D materials, including organic single crystals (OSCs), graphene, graphene derivatives, perovskites, transition metal chalcogenides (TMDCs), covalent-organic frameworks (COFs), and metal-organic frameworks (MOFs), play important roles in device applications. [1][2][3][4][5][6][7] The OSCs, graphene derivatives, perovskites and TMDCs have been researched a lot in constructing devices and charge transfer mechanism. [1][2][3][4] Exhilaratingly, conductive COFs and MOFs as active materials are just starting to play important roles in electronic devices.…”

[1][2][3][4] Exhilaratingly, conductive COFs and MOFs as active materials are just starting to play important roles in electronic devices. In spite of easy fabrication in a "top-down" approach and rational modification, the functional groups of COFs connect building blocks, but restrain diverse substrates, but also control thickness precisely at the nanoscale.…”

Ultra‐Thin Atomic Layer Deposited–Nb2O5 as Electron Transport Layer for Co‐Evaporated MAPbI3 Planar Perovskite Solar Cells

“…In recent years, organic inorganic hybrid lead halides perovskites have emerged as a significant player in the field of solid‐state semiconductors, majorly due to the promising optoelectronic properties of the material . The organic inorganic lead halides absorbers offer great promise in terms of power conversion efficiency (PCE), swiftly moving from 3% to 24.2% over a time span of a decade .…”
