Dynamic Disorder Restriction of Methylammonium (MA) Groups in Chloride-Doped MAPbBr 3 Hybrid Perovskites: A Neutron Powder Diffraction Study
(Wiley VCH Verlag, 2019-03)
The hybrid methylammonium (MA) lead halide MAPbX 3 perovskites present an appealing optoelectronic behavior with applications in high-efficiency solar cells. The orientation of the organic MA units may play an important ...
Charge-transfer dynamics of fluorescent dye-sensitized electrodes under applied biases
(American Chemical Society, 2015-07)
The development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype system ...
Mechano-Chemical Synthesis, Structural Features and Optical Gap of Hybrid CH3NH3CdBr3 Perovskite
(MDPI, 2021-10)
Hybrid methyl-ammonium (MA:CH3 NH3+) lead halide MAPbX3 (X = halogen) perovskites exhibit an attractive optoelectronic performance that can be applied to the next generation of solar cells. To extend the field of interest ...
Practical Use of Polymer Brushes in Sustainable Energy Applications: Interfacial Nanoarchitectonics for High-Efficiency Devices
(Royal Society of Chemistry, 2019-03)
The discovery and development of novel approaches, materials and manufacturing processes in the field of energy are compelling increasing recognition as a major challenge for contemporary societies. The performance and ...
Synthesis and photovoltaic applications of a 4,4′- spirobi[cyclopenta[2,1-b;3,4-b′]dithiophene]-bridged donor/acceptor dye
(American Chemical Society, 2013-09-28)
A new donor/acceptor (D-A) spiro dye (SCPDT1) featuring two bithiophene units, connected through an sp3-hybridized carbon atom, was prepared by a multistep synthetic sequence involving the convenient assembly of the spiro ...
Elucidating the Methylammonium (MA) Conformation in MAPbBr3 Perovskite with Application in Solar Cells
(American Chemical Society, 2017-11)
Hybrid organic-inorganic perovskites, MAPbX3 (X = halogen), containing methylammonium (MA: CH3-NH3+) in the large voids conformed by the PbX6 octahedral network, are the active absorption materials in the new generation ...
The detrimental influence of bacteria (E. coli, Shigella and Salmonella) on the degradation of organic compounds (and vice versa) in TiO2 photocatalysis and near-neutral photo-Fenton processes under simulated solar light
(Royal Society of Chemistry, 2012-05)
TiO2 photocatalytic and near-neutral photo-Fenton processes were tested under simulated solar light to degrade two models of natural organic matter - resorcinol (R) (which should interact strongly with TiO2 surfaces) and ...
