“…[14,194] The high efficiency PeLEDs were demonstrated on the basis of effectively eliminating of exciton quenching sites, metallic Pb species, by a modified emitting layer with stoichiometry unbalance. [46,185] Delicate control of MABr:PbBr2 molar ratio from 1:1 to 1.05:1 constraints to form metallic Pb atom and as a result current efficiency of PeLED varied from 0.183 to 21.4 cd A −1 . [14] Excess MABr prevents not only the formation of metallic Pb atoms and suppresses exciton quenching but also reduces the charge injection barrier owing to the absence of PbBr2 passivation layer with a large band gap.…”

Outstanding material properties of organic-inorganic hybrid perovskites have triggered a new research insight into the next-generation solar cells. Moreover, a wide range of controllable properties of hybrid perovskites particularly depending on crystal growth conditions enables versatile high performance optoelectronic devices such as light-emitting diodes, photodetectors and lasers beyond solar cells. This invited review article highlights recent progress of the crystallization strategies of organic-inorganic hybrid perovskites for effective light harvester or light emitter. In the first part, fundamental background on the perovskite crystalline structures and relevant optoelectronic properties such as optical band-gap, electron-hole behavior and energy band alignment are introduced. In the second part, detailed overview of the effective crystallization methods for perovskites, including thermal treatment, additives, solvent mediator, laser irradiation, nanostructure, crystal dimensionality and so on, is described to offer a comprehensive correlation among perovskite processing conditions, crystalline morphology and relevant device performances. Finally, future research direction is proposed to overcome current practical bottlenecks and move towards reliable high performance perovskite optoelectronic applications.3

High‐Purity Hybrid Organolead Halide Perovskite Nanoparticles Obtained by Pulsed‐Laser Irradiation in Liquid

et al. 2016

Nanoparticles of hybrid organic-inorganic perovskites have attracted a great deal of attention due to their variety of optoelectronic properties, their low cost, and their easier integration into devices with complex geometry, compared with microcrystalline, thin-film, or bulk metal halides. Here we present a novel one-step synthesis of organolead bromide perovskite nanocrystals based on pulsed-laser irradiation in a liquid environment (PLIL). Starting from a bulk CH NH PbBr crystal, our PLIL procedure does not involve the use of high-boiling-point polar solvents or templating agents, and runs at room temperature. The resulting nanoparticles are characterized by high crystallinity and are completely free of any microscopic product or organic coating layer. We also demonstrate the straightforward inclusion of laser-generated perovskite nanocrystals in a polymeric matrix to form a nanocomposite with single- and two-photon luminescence properties.

Quantitative Correlation of Perovskite Film Morphology to Light Emitting Diodes Efficiency Parameters

et al. 2016

View full text Add to dashboard Cite

This paper reports quantitative correlation of CH3NH3PbBr3 (MAPbBr3) thin film morphology to light emitting diode efficiency parameters. Sequential (spin coating) deposition is used for highly reproducible and dense film morphology of MAPbBr3 thin‐film. In this fabrication process using an orthogonal solvent approach, control of morphology, coverage, thickness, and optical properties in these compact thin‐films is demonstrated. Optical studies show direct correlation between morphology to dynamics of photoluminescence (PL) and absolute PL yield. Perovskite light emitting diodes (PeLEDs) are fabricated from these films to find the best ratio of PbBr2 versus MABr for optimal performance. This study demonstrates PeLEDs with high brightness, ≈1050 cd m−2 at 4.7 V (luminance efficiency ≈0.1 cd A−1), for optimal thin‐film process with state‐of‐the‐art device performance. This quantitative analysis suggests that these state‐of‐the‐art PeLEDs suffer from poor charge carrier balance (≈2%) and out‐coupling efficiency (≈6%). Interestingly, charge carrier balance and PL yield together can explain the change in PeLED efficiency modulation with film morphology. Studies on single carrier devices show that these PeLEDs are electron current dominated and charge carrier balance increases with operating bias voltage.
