Abstract

Tsai et al. (Reports, 6 April 2018, p. 67) report a uniform light-induced lattice expansion of metal halide perovskite films under 1-sun illumination and claim to exclude heat-induced lattice expansion. We show that by controlling the temperature of the perovskite film under both dark and illuminated conditions, the mechanism for lattice expansion is in fact fully consistent with heat-induced thermal expansion during illumination.

Triple-halide wide–band gap perovskites with suppressed phase segregation for efficient tandems

Journal Article Xu, Jixian ; Boyd, Caleb C. ; Yu, Zhengshan J. ; ... - Science

Wide–band gap metal halide perovskites are promising semiconductors to pair with silicon in tandem solar cells to pursue the goal of achieving power conversion efficiency (PCE) greater than 30% at low cost. However, wide–band gap perovskite solar cells have been fundamentally limited by photoinduced phase segregation and low open-circuit voltage. We report efficient 1.67–electron volt wide–band gap perovskite top cells using triple-halide alloys (chlorine, bromine, iodine) to tailor the band gap and stabilize the semiconductor under illumination. We show a factor of 2 increase in photocarrier lifetime and charge-carrier mobility that resulted from enhancing the solubility of chlorine by replacingmore »« less

Lattice Expansion in Hybrid Perovskites: Effect on Optoelectronic Properties and Charge Carrier Dynamics

Journal Article Ghosh, Dibyajyoti ; Acharya, Debdipto ; Zhou, Liujiang ; ... - Journal of Physical Chemistry Letters

Hybrid halide perovskites frequently undergo structural expansion which significantly affects their electronic properties and in particular charge carrier dynamics. Various stimuli such as residual strain, light illumination, compositional engineering may deform the soft lattices of these materials. It is essential to atomistically model how geometric changes modify electronic characteristics important for applications such as light harvesting or lighting. Using ab initio simulations, here we investigate the structural dynamics and optoelectronic properties of FAPbI₃ under tensile strain. The applied strain leads to elongation of the Pb-I bonds and a reduction of PbI₆ octahedra tilting, which manifests as a blue-shifts in bandmore »« less

Rapid Development of Hybrid Perovskites and Novel Tandem Architectures

Technical Report Hillhouse, Hugh W.

Multijunction solar cells based on epitaxially grown III-V materials hold the record for solar energy power conversion efficiency (PCE). However, due to the high cost of fabricating these devices, they are typically only used for concentrator cells and space applications. The overarching goal of this project was to develop low-cost printable hybrid perovskite (HP) materials appropriate and optimized for tandem solar cells with high power conversion efficiency under “1 Sun” illumination. Key results and findings over the course of the project we: Developed higher-performance high-bandgap (1.75 eV) perovskite materials and devices. In particular, we explored tens-of-thousands of compositions for highmore »« less

Unveiling the Photo- and Thermal-Stability of Cesium Lead Halide Perovskite Nanocrystals

Journal Article Boote, Brett W. ; Andaraarachchi, Himashi P. ; Rosales, Bryan A. ; ... - ChemPhysChem

Lead halide perovskites possess unique characteristics that are well-suited for optoelectronic and energy capture devices, however, concerns about their long-term stability remain. Limited stability is often linked to the methylammonium cation, and all-inorganic CsPbX₃ (X = Cl, Br, I) perovskite nanocrystals have been reported with improved stability. In this work, the photostability and thermal stability properties of CsPbX₃ (X = Cl, Br, I) nanocrystals were investigated via electron microscopy, x-ray diffraction, thermogravimetric analysis coupled with FTIR (TGA-FTIR), ensemble and single particle spectral characterization. CsPbBr₃ was found to be stable under 1-sun illumination for 16 h in ambient conditions, although single crystal luminescence analysis after illumination via a solar simulator indicates that the luminescence states are changing over time. CsPbBr₃ was also stable to heating to 250°C. Large CsPbI₃ crystals (34 ± 5 nm) were shown to be the least stable composition under the same conditions as both XRD reflections and Raman bands diminish under irradiation; and with heating the (black) phase reverts to the non-luminescentmore »« less

Light–ferroelectric interaction in two-dimensional lead iodide perovskites

Journal Article Kim, Dohyung ; Ievlev, Anton V. ; Ovchinnikova, Olga S. ; ... - Journal of Materials Chemistry. A

The unique physical properties of two-dimensional (2D) metal halide perovskites (MHPs) such as nonlinear optics, anisotropic charge transport, and ferroelectricity have made these materials promising candidates for multifunctional applications. Recently, fluorine derivatives such as 4,4-difluoropiperidinium lead iodide perovskite or (4,4-DFPD, C₅H₁₀F₂N)₂PbI₄ have shown strong ferroelectricity as compared to other 2D MHPs. Although it was previously addressed that the ferroelectricity in MHPs can be affected by illumination, the underlying physical mechanisms of light–ferroelectricity interaction in 2D MHPs are still lacking. Here, we explore the electromechanical responses in 4,4-(DFPD)₂PbI₄ thin films using advanced scanning probe microscopy techniques revealing ferroelectric domain structures. Inmore »« less
