Morphological Control for High Performance, Solution‐Processed Planar Heterojunction Perovskite Solar Cells
Organometal trihalide perovskite based solar cells have exhibited the highest efficiencies to‐date when incorporated into mesostructured composites. However, thin solid films of a perovskite absorber
High-quality bulk hybrid perovskite single crystals within minutes by inverse temperature crystallization
A rapid crystal growth process to obtain MAPbX3 single crystals, an order of magnitude faster than previous reports, and the grown crystals exhibit transport properties and trap densities comparable to the highest quality MAPb X3 reported to date.
Recombination Kinetics in Organic-Inorganic Perovskites: Excitons, Free Charge, and Subgap States
Organic-inorganic perovskites are attracting increasing attention for their use in high-performance solar cells. Nevertheless, a detailed understanding of charge generation, interplay of excitons and
Enhanced photoluminescence and solar cell performance via Lewis base passivation of organic-inorganic lead halide perovskites.
It is proposed that this is due to the electronic passivation of under-coordinated Pb atoms within the crystal, and power conversion efficiencies for solution-processed planar heterojunction solar cells enhanced from 13% for the untreated solar cells to 15.3% and 16.5% for thiophene and pyridine-treated solar cells, respectively.
Photo-induced halide redistribution in organic–inorganic perovskite films
This work provides visual evidence for photo-induced halide migration in triiodide perovskites and reveals the complex interplay between charge carrier populations, electronic traps and mobile halides that collectively impact optoelectronic performance.
Solution‐Grown Monocrystalline Hybrid Perovskite Films for Hole‐Transporter‐Free Solar Cells
High-quality perovskite monocrystalline films are successfully grown through cavitation-triggered asymmetric crystallization. These films enable a simple cell structure, ITO/CH3 NH3 PbBr3 /Au, with
Neutral color semitransparent microstructured perovskite solar cells.
The use of morphological control of perovskite thin films to form semitransparent planar heterojunction solar cells with neutral color and comparatively high efficiencies is reported, and the ease of "color-tinting" such microstructured perovksite solar cells is demonstrated by incorporation of a dye within the hole transport medium.
Plasmonic‐Induced Photon Recycling in Metal Halide Perovskite Solar Cells
Organic–inorganic metal halide perovskite solar cells have emerged in the past few years to promise highly efficient photovoltaic devices at low costs. Here, temperature‐sensitive core–shell Ag@TiO2
Pure crystal orientation and anisotropic charge transport in large-area hybrid perovskite films
It is found that the OPC films spontaneously form periodic microarrays that are distinguishable from general polycrystalline perovskite materials in terms of their crystal orientation, film morphology and electronic properties.
Surface structure of amorphous PMMA from SPM: auto‐correlation function and fractal analysis
The surface topography of amorphous poly(methyl methacrylate) has been investigated by scanning probe microscopy technique and analysed using an auto-correlation function approach. Spatial
