Under the spotlight: The organic–inorganic hybrid halide perovskite for optoelectronic applications

Abstract

The dawn of a new era in optoelectronic technologies has emerged with the recent development of the organic-inorganic hybrid halide perovskite. Its exceptional attributes, including high carrier mobility, an adjustable spectral absorption range, long diffusion lengths, and the simplicity and affordability of fabrication render it one of the most exceptional and market-competitive optoelectronic materials for applications in photovoltaics, light emitting diodes (LED), photodetectors, lasers, and more. Moreover, its versatility in device architecture and ability to achieve relatively high performance devices via various processing techniques makes perovskites a highly promising material for various practical applications. Here, we review the organic-inorganic hybrid halide perovskite and delve into its recent progress and relevant applications. Published by Elsevier Ltd.

Reversible air-induced optical and electrical modulation of methylammonium lead bromide (MAPbBr3) single crystals

“…The sharp peaks of MSC [ Fig. 4(a)] at 2h ¼ 6.65 , 13.3 , 20.05 , and 26.85 , consistent with the previously reported data, 45,48 represent a perfect MAPbBr 3 {001} surface with few defects. The normalized (100) peaks of MSC in air and vacuum are compared in Fig.…”

Tetragonal CH 3 NH 3 PbI 3 is ferroelectric

“…With these characteristics, the thickness of the optical absorber layer can be ≤0.5 μm, which allows the charge carriers (separated electrons and holes) to diffuse/drift throughout the entire width of the absorber without strong recombination. HaP-based solar-cell devices can, usually, function with a continuous HaP layer, that is, also without filling a high surface area, non-HaP, scaffold, such as mp-TiO 2 (11). Photogenerated electrons and holes will then spend a significant time in the bulk of the HaP film.…”

Composition and crystal structure of perovskite films attained from electrodes of used car battery

“…MAPbI 3 has tetragonal crystal structure with lattice constants a = a = 6.3115 Å, b = 6.3115 Å and c = 6.3161Å with space group P4mm [1]. However, several peaks originated from PbI 2 at 12.5 , 25.3 , 38.5 and 52.1 are clearly observed, even their intensities are higher than that of perovskite MAPbI 3 peaks.…”

“…Organolead halide perovskite materials have recently great interested for efficient active materials of high power conversion efficiency (PCE) solid state solar cells [1,2]. The PCE over 19% has already achieved using methylamonium lead iodide (CH 3 NH 3 PbI 3 , MAPbI 3 ) as active material of solar cell [3][4][5][6], prepared by simple spincoating method; therefore perovskite solar cells show great promise as a new class high performance and low cost solar cells.…”
