Optical and electrical optimization of all-perovskite pin type junction tandem solar cells
(IOP Publishing, 2020-04)
A definitive breakthrough of perovskite solar cells towards large scale industrialization is believed to be the demonstration of higher efficiencies than conventional silicon technology, suggesting the exploration of ...
Electron tunneling at the molecularly thin 2D perovskite and graphene van der Waals interface
(Nature Publishing Group, 2020-10)
Quasi-two-dimensional perovskites have emerged as a new material platform for optoelectronics on account of its intrinsic stability. A major bottleneck to device performance is the high charge injection barrier caused by ...
Partial oxidation of methane over lanthana-supported catalysts derived from perovskites
(Elsevier, 2020-03-15)
Partial oxidation of methane is the most attractive route to produce syngas, since it produces H2/CO (molar) = 2, suitable for Fischer-Tropsch and methanol synthesis, besides the low energy consumption and low tendency to ...
Atomic-level description of the CH3NH3PbI3 perovskite solar cell absorber surface
(Elsevier Ltd, 2019-06)
Methylammonium lead halide CH3NH3PbI3 (MAPI)-based hybrid organic-inorganic perovskite has recently emerged as a promising solar photovoltaic absorber exhibiting an energy conversion efficiency higher than 20 %. An ...
Analysis of substrate coverage of hybrid halide perovskite thin films deposited on glass
(Universidade Federal do Rio de Janeiro, 2018-07)
In this work we have studied coverage characteristics of organo-metal lead halide perovskite thin films deposited through the spin-coating technique onto glass substrates that were subjected to different pre-deposition ...
Surface nickel particles generated by exsolution from a perovskite structure
(Academic Press Inc Elsevier Science, 2019-02)
LaAl 1-x Ni x O 3 (with x = 0.05 and 0.2) perovskite oxides were successfully synthesized and its behavior under reduction atmosphere was studied. HRTEM and STEM studies, coupled to HAADF and EDX detection, allowed to ...
Perovskite solar cells with versatile electropolymerized fullerene as electron extraction layer
(Pergamon-Elsevier Science Ltd, 2018-08)
An electropolymerized layer of a C60 fullerene derivative was successfully used as selective contact and electron transport layer in perovskite solar cells. The electropolymeric film was formed over FTO electrodes by an ...
Recombination study of combined halides (Cl, Br, I) perovskite solar cells
(American Chemical Society, 2014-05)
We report on the preparation of a series of solution-processed perovskite solar cells based on methylammonium (MA) lead halide derivatives, MAPbX 3, which show tunable optical properties depending on the nature and ratio ...
Synthesis and characterization of alumina-embedded SrCo0.95V0.05O3 nanostructured perovskite: An attractive material for supercapacitor devices
(Elsevier Science, 2020-02-10)
Cobalt-based perovskite exhibit fascinating physical properties at the nanoscale. Better oxygen transport, higher ionic/electronic mixed conductivity and enhanced electrocatalytic activity are some of the most important ...
Sr 2 Fe 1+: X Re 1- x O 6 double perovskites: Magnetoresistance and (magneto)thermopower
(Royal Society of Chemistry, 2019-04)
Polycrystalline Sr2Fe1+xRe1-xO6 samples have been synthesized and structurally characterized by X-ray powder diffraction, transmission electron microscopy and X-ray absorption spectroscopy. Resistivity strongly increases ...
