Title: Simplification of femtosecond transient absorption microscopy data from CH₃NH₃PbI₃ perovskite thin films into decay associated amplitude maps

Abstract

Our work aims to simplify multi-dimensional femtosecond transient absorption microscopy (TAM) data into decay associated amplitude maps that describe the spatial distributions of dynamical processes occurring on various characteristic timescales. Application of this method to TAM data obtained from a model methyl-ammonium lead iodide (CH₃NH₃PbI₃) perovskite thin film allows us to simplify the dataset consisting of a 68 time-resolved images into 4 decay associated amplitude maps. Furthermore, these maps provide a simple means to visualize the complex electronic excited-state dynamics in this system by separating distinct dynamical processes evolving on characteristic timescales into individual spatial images. This approach provides new insight into subtle aspects of ultrafast relaxation dynamics associated with excitons and charge carriers in the perovskite thin film, which have recently been found to coexist at spatially distinct locations.

Connecting Femtosecond Transient Absorption Microscopy with Spatially Coregistered Time Averaged Optical Imaging Modalities

Journal Article Doughty, Benjamin ; Simpson, Mary Jane ; Das, Sanjib ; ... - Journal of Physical Chemistry. A, Molecules, Spectroscopy, Kinetics, Environment, and General Theory

Multimodal all-optical imaging involving coregistered femtosecond transient absorption microscopy (TAM), time-integrated photoluminescence (PL), and steady-state modalities such as confocal reflectance and transmission offers an appealing approach to gain a comprehensive understanding of complex electronic excited-state phenomena in spatially heterogeneous systems. A unique combination of these modalities allows us to unravel not only the competing electronic excited-state dynamical processes but also the underlying morphological information with simultaneous high temporal and spatial resolution. However, correlating the various images obtained from time-resolved and time-independent modalities is generally nontrivial and particularly challenging when the electronic dynamics under study evolve in both time and space.more »« less

Carrier-Specific Hot Phonon Bottleneck in CH₃NH₃PbI₃ Revealed by Femtosecond XUV Absorption

Journal Article Verkamp, Max ; Leveillee, Joshua ; Sharma, Aastha ; ... - Journal of the American Chemical Society

Femtosecond carrier cooling in the organohalide perovskite semiconductor CH₃NH₃PbI₃ is measured using extreme ultraviolet (XUV) and optical transient absorption spectroscopy. XUV absorption between 44 and 58 eV measures transitions from the I 4d core to the valence and conduction bands and gives distinct signals for hole and electron dynamics. The core-to-valence-band signal directly maps the photoexcited hole distribution and provides a quantitative measurement of the hole temperature. The combination of XUV and optical probes reveals that upon excitation at 400 nm, the initial hole distribution is 3.5 times hotter than the electron distribution. At an initial carrier density of 1.4more »« less

Coexistence of two electronic nano-phases on a CH₃NH₃PbI_3–xCl_x surface observed in STM measurements

Journal Article Yost, Andrew J. ; Pimachev, Artem ; Ho, Chun -Chih ; ... - ACS Applied Materials and Interfaces

Scanning tunneling microscopy is utilized to investigate the local density of states of a CH₃NH₃PbI_3-xCl_x perovskite in cross-sectional geometry. Two electronic phases, 10-20 nm in size, with different electronic properties inside the CH₃NH₃PbI_3-xCl_x perovskite layer are observed by the dI/ dV mapping and point spectra. A power law dependence of the dI/dV point spectra is revealed. In addition, the distinct electronic phases are found to have preferential orientations close to the normal direction of the film surface. Density functional theory calculations indicate that the observed electronic phases are associated with local deviation of I/Cl ratio, rather than different orientations ofmore »« less

Do grain boundaries dominate non-radiative recombination in CH₃NH₃PbI ₃ perovskite thin films?

Journal Article Yang, Mengjin ; Zeng, Yining ; Li, Zhen ; ... - Physical Chemistry Chemical Physics. PCCP

Here, we examine GBs with respect to non-GB regions (grain surfaces (GSs) and grain interiors (GIs)) in high-quality micrometer-sized perovskite CH₃NH₃PbI₃ (or MAPbI₃) thin films using high-resolution confocal fluorescence-lifetime imaging microscopy in conjunction with kinetic modeling of charge-transport and recombination processes. We show that, contrary to previous studies, GBs in our perovskite MAPbI3 thin films do not lead to increased recombination but that recombination in these films happens primarily in the non-GB regions (i.e., GSs or GIs). We also find that GBs in these films are not transparent to photogenerated carriers, which is likely associated with a potential barrier atmore »« less

Facile fabrication of large-grain CH₃NH₃PbI_3-xBr_x films for high-efficiency solar cells via CH₃NH₃Br-selective Ostwald ripening

Journal Article Yang, Mengjin ; Zhang, Taiyang ; Schulz, Philip ; ... - Nature Communications

Organometallic halide perovskite solar cells (PSCs) have shown great promise as a low-cost, high-efficiency photovoltaic technology. Structural and electro-optical properties of the perovskite absorber layer are most critical to device operation characteristics. Here we present a facile fabrication of high-efficiency PSCs based on compact, large-grain, pinhole-free CH₃NH₃PbI_3-xBr_x (MAPbI_3-xBr_x) thin films with high reproducibility. A simple methylammonium bromide (MABr) treatment via spin-coating with a proper MABr concentration converts MAPbI₃ thin films with different initial film qualities (for example, grain size and pinholes) to high-quality MAPbI_3-xBr_x thin films following an Ostwald ripening process, which is strongly affected by MABr concentration and ismore »« less
