Recent Progress in Printed Photonic Devices: A Brief Review of Materials, Devices, and Applications

“…Recently, there has been a notable increase in academic research centered on the application of perovskite materials, specifically in printed photonic devices. According to Fukuta et al [ 57 ], hybrid organic–inorganic perovskites demonstrate exceptional optoelectronic properties, including high charge carrier mobilities, prolonged carrier lifetimes, and significant absorption coefficients. Perovskite-based devices have exhibited a commensurate level of efficacy compared to their conventional counterparts.…”

“…Rao et al [ 52 ] have reported that organic semiconductors comprising small molecules and polymers offer several advantages over their inorganic counterparts. Recent studies [ 54 , 57 ] have shown that perovskite materials are promising candidates for solar cells and LEDs due to their outstanding optoelectronic properties. It should be noted that by incorporating two-dimensional materials, such as graphene, and developing hybrid material systems present additional opportunities for improving device performance.…”

Temperature-Induced Reversible Photoluminescence Switching and Ultraviolet-Pumped Light-Emitting Diode Applications of a Perovskite (C6H10N2)2MnCl6·2H2O Crystal

“…Organic–inorganic hybrid metal halide perovskites with excellent optoelectronic properties and promising applications in many aspects, such as lasers, solar cells, photodetectors, and light-emitting diodes, have attracted widespread attention. − Benefiting from 6s 2 lone-pair electronic configuration, lead halides usually present excellent optoelectronic properties, and a series of Pb-based perovskites with excellent characteristics have been exploited. , However, the inherent toxicity of heavy metal lead to human health and the environment cannot be ignored; hence, the development of lead-free hybrid perovskites has received increasing attention. − In addition, from the aspect of spatial structure, organic–inorganic hybrid perovskites can demonstrate three-dimensional (3D), two-dimensional (2D), one-dimensional (1D), and zero-dimensional (0D) structures by adopting suitable organic and metal halide constituents. − Among them, low-dimensional hybrid materials usually show unique photophysical performances (e.g., broad luminescence, large Stokes shift, and high efficiency) due to high quantum confinement . Specifically, the reduction of dimensionality leads excitons to be confined in inorganic polyhedron and consequently facilitates the formation of self-trapping excitons (STEs). , Furthermore, the PLQY is inclined to increase with the reduction of dimensionality.…”

Structural Stability, Tunable Electronic, and Optical Properties of XSi2N4/Cs2SnI6 (X = Cr, Mo, W) Heterostructures: First‐Principles Studies

“…These remarkable features position PSCs as promising candidates for a wide range of photonic applications, such as solar cells, [1][2][3] lightemitting diodes, [4] photodetectors, [5] and lasers. [6,7] In the beginning, all-solid lead halide PSCs demonstrated efficiency of only 3.8%. [8][9][10] In the past decade, a rapid succession of efficiency improvements has propelled them to achieve efficiencies exceeding 25%.…”
