“…[152] A very exciting development has been the creation of hysteresis-free devices in DPP-doped perovskite FETs by depositing polyethylenimine ethoxylated (PEIE) onto the surface of the perovskite. [152] More recently, hysteresis-free devices with high electron mobility have been developed using a different version of the triple cation perovskite (Cs 0.10 FA 0.90 Pb(I 0.83 Br 0.17 ) 3 ) doped with Rb + to passivate traps in the perovskite bulk and reduce ion migration. [52] Vasilopoulou et al used higher amounts of Rb + salts and reported only p-type operation for Rb 0.15 (MAFA) 0.85 PbI 3 .…”

Field-effect transistors (FETs) are key elements in modern electronics and hence are attracting immense scientific and commercial attention. The recent emergence of metal halide perovskite materials and their tremendous success in the field of photovoltaics have triggered the exploration of their application in other (opto)electronic devices, including FETs and phototransistors. In this review, the current status of the field is discussed, the challenges are highlighted, and an outlook for the future perspectives of perovskite FETs is provided. First, attention is drawn to the device physics and the fundamental processes that influence these devices, including the role of ion migration and defects, effects of temperature, light, and measurement conditions. Next, the performance of perovskite transistors and phototransistors reported to date are surveyed and critically assessed. Finally, the key challenges that impede perovskite transistor progress are outlined and discussed. The insights gained from the study of other perovskite optoelectronic devices may be adopted to address these challenges and advance this exciting field of research closer to the industrial application are examined.

“…Solar energy is mainly used for this due to its capacity to imitate the natural photosynthesis process to transform solar energy into chemical energy. The photocatalytic reduction of CO 2 into valued fuels like formic acid, methane, and methanol is of particular importance [234][235][236]. In the last decades, this has received great attention and we have become acquainted with the enhanced release of the greenhouse gas CO 2 into our atmosphere and the potential and real power supply shortage.…”

“…The CO 2 reduction by photosensitive semiconductor catalysts yields highly sought products, e.g., formic acid, methane, formaldehyde, and methanol, etc. Several compounds, including metal complexes, can function as electrocatalysts for CO 2 reduction [235,236]. Bismuth and graphene's role is vital and has been studied widely in CO 2 conversion to valued products.…”

Photocatalysis is a classical solution to energy conversion and environmental pollution control problems. In photocatalysis, the development and exploration of new visible light catalysts and their synthesis and modification strategies are crucial. It is also essential to understand the mechanism of these reactions in the various reaction media. Recently, bismuth and graphene’s unique geometrical and electronic properties have attracted considerable attention in photocatalysis. This review summarizes bismuth-graphene nanohybrids’ synthetic processes with various design considerations, fundamental mechanisms of action, heterogeneous photocatalysis, benefits, and challenges. Some key applications in energy conversion and environmental pollution control are discussed, such as CO2 reduction, water splitting, pollutant degradation, disinfection, and organic transformations. The detailed perspective of bismuth-graphene nanohybrids’ applications in various research fields presented herein should be of equal interest to academic and industrial scientists.

“…As a result, nearly six years after the introduction of the PeLET concept, both conventional perovskite field‐effect transistors (FETs) and LETs cannot perform to their full potential. [ 5,13 ] So far, only a few works reported balanced ambipolar transport [ 14–17 ] or light emission from perovskite field‐effect transistors, [ 2,18–20 ] indicative of the severe limitations posed by the intrinsic transport and electroluminescence characteristics of HOIP materials.…”

Solution‐processed hybrid organic–inorganic perovskite light‐emitting transistors (PeLETs) suffer from low brightness and environmental instability induced by temperature‐activated trapping, ionic motion, and polarization effects, which so far have been hindering the realization of devices operating at room temperature. Here high quality thermally co‐evaporated methylammonium lead iodide perovskite films are employed to minimize ionic motion and significantly improve the electroluminescence characteristics of the perovskite active layer, enabling stable device operation up to ≈ 310 K. The demonstration of PeLETs operating at and beyond room‐temperature paves the way for practical applications in the rapidly evolving area of solid‐state lighting, active‐matrix displays, and visible light communications.
