Organic–inorganic hybrid perovskite compounds are currently the archetypal materials for high performance photovoltaic (PV) and optoelectronic devices. However, the remaining bottlenecks preventing their large-scale production are their environmental/thermal instability and lead toxicity. Herein, we demonstrate a novel approach to synthesize single-phase electrospun Cs2SnIxCl6–x double perovskites with varying halide content (I, Cl, or mixed I/Cl) as active materials for potential application in...

A comprehensive analysis of low coverage CO adsorption on Ni and Cu low-index miller surfaces – (100), (110), and (111) – over all the possible adsorption sites is presented. Systems are theoretically studied within an accurate adsorption model using RPBE density functional calculations to obtain electronic and geometrical structure predictions along with their corresponding adsorption energy computations. Based on the surface- and site-dependent comparisons of the adsorption mechanisms, we were...

CO adsorption on Cu(100), (110), and (111) surfaces has been extensively studied using Kohn–Sham density functional theory calculations. A holistic analysis of adsorption energies, charge transfer, and structural changes has been employed to highlight the variations in adsorption mechanisms upon changing the surface type and the adsorption site. Each surface, with its unique arrangement of atoms, resulted in a varying adsorbate behavior, although the same adsorption site is considered. This dire...

Integration of distributed generations (DGs) to electrical power systems is now being increasingly applied to act as an auxiliary source of energy with the main power feeder. For the nowadays trend of relying on the renewable energy resources as solutions for environmentally sustainable energy production, Photovoltaic (PV) generators - which are considered a type of inverter-based distributed generators - are considered as one of the promising solutions. In this paper, power flow analysis is pre...
