Recent advancements in halide perovskite nanomaterials and their optoelectronic applications

Abstract

Lead halide perovskite nanomaterials are among the forefront of developing materials for energy harvesting and light‐emitting applications. Their unique defect tolerance, high photoluminescent quantum yields, and vast synthetic tunability make them attractive for many optoelectronic applications. In this review article, the broad synthetic toolbox of these materials is discussed, including how synthetic conditions can tune the optical properties and dimensionality of the resulting perovskite nanomaterial. Additionally, we discuss the brief history, current state, and bright future of these materials, in tune with their optoelectronic applications, namely in light‐emitting diodes, lasing, photovoltaics, photon interconversion applications, and in photodetectors.

A Single‐Dot Perovskite Spectrometer

“…Hybrid organic–inorganic perovskites, a well‐studied semiconductor family, not only possess high carrier mobility and a suitable bandgap but also have adjustable components and energy band structures. [ 22 ] This makes them perfect materials for spectrum response modulation. Based on our previous work, the utilization of perovskite diodes has a response speed advantage.…”

Inkjet Printed Quantum Dots Color Conversion Layers for Full-Color Micro-LED Displays

“…Thus color conversion has become a popular method to achieve full color Micro-LED display [21,22]. On the other hand, QDs have extraordinary properties such as size-dependent energy gap, narrow emission spectrum, high luminescence efficiency, large stokes shift and less reabsorption [23][24][25][26][27]. It has become one of the crucial building blocks of color conversion [11,22,28,29].…”

Enhanced Structural Stability and Pressure‐Induced Photoconductivity in Two‐Dimensional Hybrid Perovskite (C6H5CH2NH3)2CuBr4

“…in current commercial production of perovskite solar cells have severely limited their practical applicable scope as optoelectronic devices. [3][4][5][6][7][8] Two-dimensional (2D) perovskites with high thermodynamic stability are perfect candidates as absorbent layers for perovskite solar cells because of their effective charge transportation for metal-halogen octahedral layers. [9,10] Especially 2D non-toxic perovskite materials can simultaneously solve the problems of poor stability and high toxicity of solar cell devices.…”
