Buried Interface Passivation of Perovskite Solar Cells by Atomic Layer Deposition of Al2O3
(American Chemical Society, 2023-04-14)
Despite having long excited carrier lifetimes and high mobilities in hybrid halide perovskite materials, conventional (n-i-p) devices exhibit significant interfacial nonradiative recombination losses that are little ...
Photocatalytic Properties of a Palladium Metallosquare with Encapsulated Fullerenes via Singlet Oxygen Generation
(American Chemical Society, 2019-08-12)
Singlet oxygen has recently attracted a great deal of attention due to its strong oxidizing properties, which makes it useful in organic synthesis and biological studies. However, the photosensitizers that are required for ...
Self-Assembly of Di-N-Heterocyclic Carbene-Gold-Adorned Corannulenes on C60
(Wiley, 2017-08-04)
The deprotonation of a corannulene-based bisazolium salt allowed the preparation of a corannulene-based NHC di-AuI complex. The prepared di-AuI-complex was tested in the recognition of fullerene-C60, demonstrating good ...
Welcoming the First Decade of Perovskite Solar Cells
(Wiley, 2019-09-02)
The swift emergence of perovskite solar cells (PSCs) is a “miracle” development in the history of photovoltaics. Since Miyasaka and co‐workers (Toin University of Yokohama, Japan) reported the first use of halide perovskites ...
Single-Exciton Amplified Spontaneous Emission in Thin Films of CsPbX3 (X = Br, I) Perovskite Nanocrystals
(American Chemical Society, 2019-09-23)
CsPbX3 perovskite nanocrystals (PNCs) have emerged as an excellent material for stimulated emission purposes, with even more prospective applications than conventional colloidal quantum dots. However, a better understanding ...
Catalyst design for highly efficient carbon dioxide hydrogenation to formic acid under buffering conditions
(Elsevier, 2020-03-19)
We report on new ruthenium complexes as catalysts for the efficient transformation of CO2 into formic acid employing basic ionic liquids as buffering media. Remarkably, these complexes catalyze the hydrogenation of CO2 ...
High-Fidelity, Narcissistic Self-Sorting in the Synthesis of Organometallic Assemblies from Poly-NHC Ligands
(Wiley, 2017-05)
Highly selective, narcissistic self-sorting has been observed in the one-pot synthesis of three organometallic molecular cylinders of type [M3{L-(NHC)3}2](PF6)3 (M=Ag+, Au+; L=1,3,5-benzene, triphenylamine, or 1,3,5-trip ...
Methylammonium Lead Bromide Perovskite Battery Anodes Reversibly Host High Li-Ion Concentrations
(American Chemical Society, 2017-04)
Ions migrate through the hybrid halide perovskite lattice, allowing for a variety of electrochemical applications as perovskite-based electrodes for batteries. It is still unknown how extrinsic defects such as lithium ions ...
Tunable hysteresis effect for perovskite solar cells
(Royal Society of Chemistry, 2017-09-14)
Perovskite solar cells (PSCs) usually suffer from a hysteresis effect in current–voltage measurements,
which leads to an inaccurate estimation of the device e
fficiency. Although ion migration, charge trapping/
detrapping, ...
Changes from Bulk to Surface Recombination Mechanisms between Pristine and Cycled Perovskite Solar Cells
(American Chemical Society, 2017)
Several aspects on the photophysical characterization of lead halide hybrid organic–inorganic perovskite solar cells remain unsolved. It has been observed that ionic transport and polarization of the interfaces cause very ...
