Abstract

Here, an electrochemical/chemical route is introduced to deposit both textured and epitaxial films of methylammonium lead iodide (MAPbI₃) perovskites. The perovskite films are produced by chemical conversion of lead dioxide films that have been electrodeposited as either textured or epitaxial films onto [111]-textured Au and [100] and [111] single-crystal Au substrates. The epitaxial relationships for the MAPbI₃ films are MAPbI₃(001)[010]∥PbO₂(100)<001> and MAPbI₃(110)[111]∥PbO₂(100)<001> regardless of the Au substrate orientation, because the in-plane order of the converted film is controlled by the epitaxial PbO₂ precursor film. The textured and epitaxial MAPbI₃ films both have trap densities lower than and photoluminescence intensities higher than those of polycrystalline films produced by spin coating.

Nanometer-Thick Gold on Silicon as a Proxy for Single-Crystal Gold for the Electrodeposition of Epitaxial Cuprous Oxide Thin Films

Journal Article Switzer, Jay A. ; Hill, James C. ; Mahenderkar, Naveen K. ; ... - ACS Applied Materials and Interfaces

Here, single-crystal Au is an excellent substrate for electrochemical epitaxial growth due to its chemical inertness, but the high cost of bulk Au single crystals prohibits their use in practical applications. Here, we show that ultrathin epitaxial films of Au electrodeposited onto Si(111), Si(100), and Si(110) wafers can serve as an inexpensive proxy for bulk single-crystal Au for the deposition of epitaxial films of cuprous oxide (Cu₂O). The Au films range in thickness from 7.7 nm for a film deposited for 5 min to 28.3 nm for a film deposited for 30 min. The film thicknesses are measured by low-anglemore »« less

Substitutional Growth of Methylammonium Lead Iodide Perovskites in Alcohols

Journal Article Acik, Muge ; Alam, Todd M. ; Guo, Fangmin ; ... - Advanced Energy Materials

Abstract Methylammonium lead iodide (MAPbI ₃ ) perovskites are organic–inorganic semiconductors with long carrier diffusion lengths serving as the light‐harvesting component in optoelectronics. Through a substitutional growth of MAPbI ₃ catalyzed by polar protic alcohols, evidence is shown for their substrate‐ and annealing‐free production and use of toxic solvents and high temperature is prevented. The resulting variable‐sized crystals (≈100 nm–10 µm) are found to be tetragonally single‐phased in alcohols and precipitated as powders that are metallic‐lead‐free. A comparatively low MAPbI ₃ yield in toluene supports the role of alcohol polarity and the type of solvent (protic vs aprotic). The theoreticalmore »« less

Optical response of mixed methylammonium lead iodide and formamidinium tin iodide perovskite thin films

Journal Article Ghimire, Kiran ; Zhao, Dewei ; Yan, Yanfa ; ... - AIP Advances

Here, mixed tin (Sn) and lead (Pb) based perovskite thin films have been prepared by solution processing combining methylammonium lead iodide (MAPbI₃) and formamidinium tin iodide (FASnI₃) precursors. Optical response in the form of complex dielectric function (ε = ε₁ + iε₂) spectra and absorption coefficient (α) spectra of (FASnI₃)_1-x(MAPbI₃)_x based perovskite films have been extracted over a spectral range 0.74 to 5.89 eV using spectroscopic ellipsometry. Absorption band edge energy changes as a function of composition for films including FASnI₃, MAPbI₃, and mixed x = 0.20, 0.35, 0.40, and 0.6 (FASnI₃)_1-x(MAPbI₃)_x perovskites. (FASnI₃)_0.60(MAPbI₃)_0.4 is found to have the minimummore »« less

Evolution of Iodoplumbate Complexes in Methylammonium Lead Iodide Perovskite Precursor Solutions

Journal Article Sharenko, Alexander ; Mackeen, Cameron ; Jewell, Leila ; ... - Chemistry of Materials

Here in this study we investigate the local structure present in single-step precursor solutions of methylammonium lead iodide (MAPbI₃) perovskite as a function of organic and inorganic precursor ratio, as well as with hydriodic acid (HI), using X-ray absorption spectroscopy. An excess of organic precursor as well as the use of HI as a processing additive has been shown to lead to the formation of smooth, continuous, pinhole free MAPbI₃ films, whereas films produced from precursor solutions containing molar equivalents of methylammonium iodide (MAI) and PbI₂ lead to the formation of a discontinuous, needlelike morphology. We now show that asmore »« less

Moisture-Induced Structural Degradation in Methylammonium Lead Iodide Perovskite Thin Films

Journal Article Toloueinia, Panteha ; Khassaf, Hamidreza ; Shirazi Amin, Alireza ; ... - ACS Applied Energy Materials

Methylammonium lead iodide (CH₃NH₃PbI₃, MAPbI₃) belongs to the group of organic–inorganic halide perovskites (OIHPs) that exhibit exceptional electrical and optical behavior suitable for photovoltaic applications. However, improving its structural and chemical stability and robustness remains a challenge for OIHPs to be considered a feasible active material in optoelectronic devices. This is due to the fact that this material is very susceptible to degrade under various intrinsic and extrinsic factors. Therefore, it is crucial to understand the mechanisms through which MAPbI₃ undergoes chemical degradation under operating conditions such as a relatively humid environment. We present the structural characteristics of MAPbI₃ undermore »« less
