Spray-Pyrolyzed ZnO as Electron Selective Contact for Long-Term Stable Planar CH3NH3PbI3 Perovskite Solar Cells
(American Chemical Society, 2018)
Electron selective contacts (ESCs) play an important role in the performance of perovskite solar cells (PSCs). ZnO has attracted important attention as a good material for ESCs because of its matched energy levels with ...
Ion-mediated hopping electrode polarization model for impedance spectra of CH3NH3PbI3
(American Institute of Physics, 2020-08-18)
Methylammonium lead iodide (CH3NH3PbI3) is one of the most attractive materials for optoelectronic applications, and it is the most typical absorber in perovskite solar cells, which are unprecedentedly successful devices ...
Single Step Deposition of an Interacting Layer of Perovskite Matrix with Embedded Quantum Dots
(Royal Society of Chemistry, 2016)
Hybrid lead halide perovskite (PS) derivatives have emerged as very promising materials for the development of optoelectronic devices in the last few years. At the same time, inorganic nanocrystals with quantum confinement ...
WO3/BiVO4: impact of charge separation at the timescale of water oxidation
(Royal Society of Chemistry, 2019-01-16)
The four hole oxidation of water has long been considered the kinetic bottleneck for overall solar-driven water splitting, and thus requires the formation of long-lived photogenerated holes to overcome this kinetic barrier. ...
A Matter of Fidelity: Self‐Sorting Behavior of Di‐Gold Metallotweezers
(Wiley, 2019-06)
Cation‐induced high selective self‐sorting is observed for reactions involving a series of di‐gold metallotweezers. The variation of the nature of the arms of the tweezers (benzo‐imidazolylidene or pyrene‐imidazolylidene), ...
(Di)triazolylidene manganese complexes in catalytic oxidation of alcohols to ketones and aldehydes
(Royal Society of Chemistry, 2019)
Carbonyl manganese complexes with chelating or bridging mesoionic di(1,2,3-triazolylidene) ligands were efficiently synthesised and fully characterised, including the X-ray diffraction study of a bimetallic manganese(0) ...
Catalysis Meets Spintronics; Spin Potentials Associated with Open-Shell Orbital Configurations Enhance the Activity of Pt3Co Nanostructures for Oxygen Reduction: A Density Functional Theory Study
(American Chemical Society, 2020)
One of the main obstacles in the implementation of hydrogen fuel cells (HFC) lies in the efficiency loss due to the overpotential of the oxygen reduction reaction (ORR). Nowadays, the best catalysts for cathodes in HFC are ...
A palladium-hinged organometallic square with a perfect-sized cavity for the encapsulation of three heteroguests
(Royal Society of Chemistry, 2019-12-25)
A nanometer-sized tetrapalladium metallosquare with a pyrene-bisimidazolylidene ligand was found to display a perfect-sized cavity for the encapsulation of three heteroguests, enabling the formation of quintuple D–A–D–A–D ...
Quantification of Ionic Diffusion in Lead Halide Perovskite Single Crystals
(American Chemical Society, 2018)
Lead halide perovskites are mixed electronic–ionic semiconductors that have recently revolutionized the photovoltaics field. The physical characterization of the ionic conductivity has been rather elusive because of the ...
