Metal Halide Perovskite for next-generation optoelectronics: progresses and prospects

Abstract

Metal halide perovskites (MHPs), emerging as innovative and promising semiconductor materials with prominent optoelectronic properties, has been pioneering a new era of light management (ranging from emission, absorption, modulation, to transmission) for next-generation optoelectronic technology. Notably, the exploration of fundamental characteristics of MHPs and their devices is the main research theme during the past decade, while in the next decade, it will be primarily critical to promote their implantation in the next-generation optoelectronics. In this review, we first retrospect the historical research milestones of MHPs and their optoelectronic devices. Thereafter, we introduce the origin of the unique optoelectronic features of MHPs, based on which we highlight the tunability of these features via regulating the phase, dimensionality, composition, and geometry of MHPs. Then, we show that owing to the convenient property control of MHPs, various optoelectronic devices with target performance can be designed. At last, we emphasize on the revolutionary applications of MHPs-based devices on the existing optoelectronic systems. This review demonstrates the key role of MHPs played in the development of modern optoelectronics, which is expected to inspire the novel research directions of MHPs and promote the widespread applications of MHPs in the next-generation optoelectronics.

In-situ growth of low-dimensional perovskite-based insular nanocrystals for highly efficient light emitting diodes

“…For low-dimensional structures, the application of additives to regulate perovskite growth enables the elimination of n = 1 layered perovskite that radiate slower than those with higher dimensionalities 11 , 12 . Furthermore, additives utilized for manipulating perovskite growth can also passivate surface defects 13 .…”

Mixed Ionic‐Electronic Conduction Enables Halide‐Perovskite Electroluminescent Photodetector

“…Therefore, ELPD will find applications in the emerging multifunctional optoelectronics. [1,55] To be stable over time, ELPD response requires stationary Φ(V) ion ; however, dynamic accumulation of ions at the interfaces results in a time-dependent Φ(V, t) ion . [56,57] For our MSM ELPD device, this is a key source of instability of responses under DC bias.…”

Seeking for Cost-Effective Tin Iodide Source toward Efficient Lead-Free Tin Triiodide Perovskite Solar Cells: Advances and Prospects

“…During the past decade, metal halide perovskites (MHPs) have emerged as the rising star in the field of next-generation optoelectronics (e.g., solar cells, light emitting iodides, lasers, and photodetectors) owing to their superb optoelectronic properties. 1 Notably, lead halide perovskites (LHPs) have made tremendous progress in photovoltaics application, and the power conversion efficiency (PCE) of LHPs-based single junction solar cells has reached a certified high value of 25.7%, 2 demonstrating their great promise in future commercialization. Nevertheless, LHPs still suffer from two challenges: (i) potential environmental toxicity due to the containing of heavy metal Pb 3 and (ii) a bottleneck of PCE enhancement due to the relative larger band gap (>1.5 eV) than the ideal one (1.2−1.4 eV) according to the Shockley−Queisser (S−Q) limit theory.…”
