The structural and electrochemical properties of CuCoO2 crystalline nanopowders and thin films: conductivity experimental analysis and Insights from density functional theory calculations
(MDPI, 2023-08-11)
A novel manufacturing process is presented for producing nanopowders and thin films of CuCoO2 (CCO) material. This process utilizes three cost-effective synthesis methods: hydrothermal, sol-gel, and solid-state reactions. ...
Dielectric relaxation dynamics of high-temperature piezoelectric polyimide copolymers
(Springer, 2015-08)
Polyimide copolymers have been prepared based on different diamines as comonomers: a diamine without CN groups and a novel synthesized diamine with two CN groups prepared by polycondensation reaction followed by thermal ...
Thermodynamic stability screening of IR-photonic processed multication halide perovskite thin films
(Royal Society of Chemistry, 2021-11-24)
We report a material screening study for phase transitions of multication hybrid halide perovskite films. Two
hundred sixty-six films processed with flash infrared annealing were optically and structurally characterized.
This ...
Real-Time Observation of Iodide Ion Migration in Methylammonium Lead Halide Perovskites
(Wiley, 2017)
Organic-inorganic metal-halide perovskites (e.g. CH3NH3PbI3-xClx) emerged as a promising opto-electronic material. However, the Shockley–Queisser Limit for the power conversion efficiency (PCE) of perovskite-based photovoltaic ...
Porosity dependence of electron percolation in nanoporus TiO2 layers
(American Institute of Physics, 2008)
The electron diffusion coefficient at varying porosity has been determined in a series of
nanostructured TiO2 films of different initial thicknesses. The porosity was changed by applying
different pressures prior to ...
Formation Criteria of High Efficiency Perovskite Solar Cells in Ambient Conditions
