ruthenium molecular dye, wide absorption range, direct and tunable bandgaps, superior charge carrier mobility, and long carrier diffusion length. [6,[43][44][45] Although it has been synthesized for over 100 years, Mitzi et al. were the first to investigate the electrical properties of tin-based perovskite in 1994, [46] which was later used in numerous devices, including field effect transistors (FETs) and LEDs. [47][48][49] The attention toward metal halide perovskites sparked yet again in 2009, [42] and they were later named one of the most promising emerging technologies in 2016. In brief, metal halide perovskites can be divided into two types based on their crystal structure motif: (i) 3D-structured perovskite (AMX 3 ) and (ii) 2D-structured perovskite (A 2 MX 4 ). The structure of the perovskite could either be 2D or 3D, while the dimensions of the perovskite probably belong to 0D-3D. The term "perovskite" implies to the general class of materials derived from an elemental composition of AMX 3 and demonstrates the crystal structure of perovskite crystal CaTiO 3 , where the divalent metal M resides at the body center and surrounded by six X-anions located at the face centers in an octahedral cluster. The MX 6 in the octahedral cluster may form an extended 3D structure by all-corner-connected type with A-cation sitting at the center. It could also form a 2D perovskite when the 3D perovskite network is cut into one-layer-thick slices along the 〈100〉 direction and separates them apart. In principle, 2D perovskite is the easiest to synthesize because of its natural layered structure, which is held together by weak van der Waals forces. Dou et al. reported the large-scale synthesis of the monolayer (C 4 H 9 NH 3 ) 2 -PbBr 4 by a chemical method. [50] Along the same lines, several groups have prepared and characterized nanomaterials composed of various forms of perovskites. [51][52][53] Also, our group has recently successfully prepared a low-dimensional mixed 2D/3D perovskite using the protonated salt of amino valeric acid iodide (AVAI) as an organic precursor mixed with PbI 2 , in which a yellowish film was containing needle-like crystallite formed. [54] In this topical review, we present the latest advances in the synthesis of low-dimensional perovskites and the growth mechanism to develop a strategy to achieve best performing devices. Later, we focus the instability and a cost-effective solution to circumvent this problem, which is vital for the eventual deployment of perovskite solar cells to consumers market. We present an analysis of the origins for instability in perovskite solar cells, and present a summary of the main achievements and possible future developments of these low-dimensional perovskite. [2,55] Perovskite solar cells have been heralded as one of the most promising emerging technologies in 2016 because of the very high power conversion efficiency of 22% and the low cost of generating electricity compared to even fossil fuels. These are formed with various dimensionalities and can be fully mani...

“…In spite of several attempts on electrostatic gating of hybrid perovskite FETs, success has been rather limited. [25][26][27] In this paper, we report on the fabrication and room-temperature operation of FETs based on the halide hybrid perovskites. We obtained balanced electron and hole transport, in agreement with the high efficiency of PV cells based on these compounds, having mobilities of ∼1 cm 2 /Vs.…”

The hybrid halide perovskites combine the low-cost processing characteristics of organic materials with the performance factors of inorganic compounds. Recently the power conversion efficiencies of perovskite photovoltaic solar cells have reached a respective value of ∼20%. The charge transport properties were indirectly approximated in these compounds because of lack of available field-effect transistors (FETs). Here we report the fabrication and room-temperature operation of FETs based on the hybrid perovskites. We obtained balanced electron and hole transport with mobilities of ∼1 cm 2 / Vs. We also found that the yield, as well as the operational and environmental stability of the fabricated transistors is limited.Inorganic perovskite materials have attracted significant research effort given their rich physical properties that includes high-temperature superconductivity, colossal magnetoresistance, ferroelectricity, diverse magnetic properties, etc. [1,2] Their structure has the general formula ABX 3 , where the cation B resides in the center of the corner sharing BX 6 octahedra, the X anions occupy the corners; whereas cation A is surrounded by eight such octahedra (see, for example, SrTiO 3 , YMnO 3 , YVO 3 , and LaMnO 3 ). The newest member of the perovskite family, namely the organic-inorganic perovskites, have recently emerged as an intriguing class of materials, which combine the low-cost processing and versatility characteristics to organic materials with the performance factors of inorganic compounds. [3,4] In particular, organo-lead halide perovskites (A + PbX 3 ), where A + is the organic cation and X denotes the halogen atom, have quickly become one of the hottest topics of research these days, in spite of the concerns related to the environmental hazard posed by the lead component. For example, the power conversion efficiency of hybrid perovskite photovoltaic (PV) solar cells has exceeded 19%, [5] and the light-emitting diodes (LEDs) based on these compounds rival the best on the market.[6] In addition, hybrid perovskite semiconductors exhibit wavelength-tunable photoluminescence (PL) emission, [7] laser action, [8] and charge carrier diffusion lengths of the order of hundreds of micrometers.[9] Surprisingly, these compounds also show interesting spin-related properties, including magneto-photocurrent, magneto-electroluminescence, and magneto-PL, in spite of their fast spin relaxation that is due to the strong spin-orbit coupling. [10,11] The hybrid perovskites based on methylammonium (where A + = CH 3 NH 3 + ) are most common, but other organic cations, such as ethylammonium CH 3 CH 2 NH 3 + or formamidinium NH 2 CH = NH 2 + have also been explored. [12,13] It has been found that the anion (X = I, Br, Cl) impacts a variety of physical properties such as the crystal quality, [14] band-gap, [15] PV solar cell efficiency, [16] exciton-binding energy [17] and the amplified spontaneous emission wavelength.[8] Mixed halide perovskites such as CH 3 NH 3 PbI 3-x Cl x , offer the possibility of ...

“…1, [5][6][7][8][9][10][11][12][13] The earliest scientific work on perovskites was conducted in the late 70s by Weber, [14][15][16] who characterized these materials in detail. Significant advances were made in the 90s and 2000s by Mitzi et al [17][18][19] leading to the first implementation of perovskites in devices. Interest seemed to subside for a while until the first reports on the utilization of organic-inorganic lead halide perovskites as sensitizers in solar cells in 2009 (Kojima et al 6 ) and the demonstration of their light emission in 2012.…”

Lead halide perovskite nanocrystals (NCs) are receiving a lot of attention nowadays, due to their exceptionally high photoluminescence quantum yields reaching almost 100% and tunability of their optical band gap over the entire visible spectral range by modifying composition or dimensionality/size. We review recent developments in the direct synthesis and ion exchange-based reactions, leading to hybrid organic-inorganic (CH 3 NH 3 PbX 3 ) and all-inorganic (CsPbX 3 ) lead halide (X = Cl, Br, I) perovskite NCs, and consider their optical properties related to quantum confinement effects, single emission spectroscopy and lasing. We summarize recent developments on perovskite NCs employed as an active material in several applications such as light-emitting devices, solar cells and photodetectors, and provide a critical outlook into the existing and future challenges.
