Femtosecond Charge-Injection Dynamics at Hybrid Perovskite Interfaces
(Wiley VCH Verlag, 2017-09)
With a power conversion efficiency (PCE) exceeding 22 %, perovskite solar cells (PSCs) have thrilled photovoltaic research. However, the interface behavior is still not understood and is a hot topic of research: different ...
Ultrafast all-optical modulation in 2D hybrid perovskites
(American Chemical Society, 2019-07-17)
Two-dimensional (2D) hybrid organic-inorganic Ruddlesden-Popper perovskites (RPPs) have been recently shown to exhibit large nonlinear optical properties due to the strong excitonic effects present in their multiple quantum ...
Direct observation of surface polarization at hybrid perovskite/Au interfaces by dark transient experiments
(American Institute of Physics, 2020-05)
A distinctive feature of hybrid perovskite light-absorbing materials is the non-negligible ionic conductivity influencing photovoltaic performance and stability. Moving ions or vacancies can naturally accumulate at the ...
Choice of hybrid functional and basis set optimization to calculate the structural, electronic, mechanical, and vibrational properties of BaSnO3
(2016-06-01)
This work aimed to study the influence of seven hybrid functionals (B3LYP, B1WC, B3PW, PBE0, PBESOL0, SOGGAXC, and WC1LYP) and selected basis sets in the CRYSTAL software library on the calculated structural, electronic, ...
Nontemplate Synthesis of CH3NH3PbBr3 Perovskite Nanoparticles
(American Chemical Society, 2014-01)
To date, there is no example in the literature of free, nanometer-sized, organolead halide CH3NH3PbBr3 perovskites. We report here the preparation of 6 nm-sized nanoparticles of this type by a simple and fast method based ...
Enhanced stability in CH3NH3PbI3 hybrid perovskite from mechano-chemical synthesis: structural, microstructural and optoelectronic characterization
(Nature, 2020-12)
Among the hybrid organic–inorganic perovskites MAPbX3 (MA: methyl-ammonium CH3–NH3+, X = halogen), the triiodide specimen (MAPbI3) is still the material of choice for solar energy applications. Although it is able to absorb ...
Crystal Growth, Structural Phase Transitions, and Optical Gap Evolution of CH 3 NH 3 Pb(Br 1-x Cl x ) 3 Perovskites
(American Chemical Society, 2019-01)
Chemically tuned inorganic-organic hybrid halide perovskites based on bromide and chloride anions CH 3 NH 3 Pb(Br 1-x Cl x ) 3 have been crystallized and investigated by synchrotron X-ray diffraction (SXRD), scanning ...
Modeling of Thermal Effect on the Electronic Properties of Photovoltaic Perovskite CH3NH3PbI3: The Case of Tetragonal Phase
(2016)
Hybrid organic-inorganic perovskites are semiconductors with disordered structures and remarkable properties for photovoltaic applications. Many theoretical investigations have attempted to obtain structural models of the ...
