In this paper, a n-i-p planar heterojunction simulation of Sn-based iodide perovskite solar cell (PSC) is proposed. The structure consists Fluorine-doped tin oxide (FTO) substrate on which titanium (TiO2) placed; material will act as an electron transporting layer (ETL); then, we have the CH3NH3SnI3 (MASnI3) absorber and next copper zinc sulfide (CZTS) that function hole (HTL). This used due to its simple synthesis process band tuning, in addition presenting good electrical properties...
Mixed-halide perovskites enable the creation of high-performance and low-cost solar cells. Chloride incorporation enhances film morphology, carrier diffusion length, stability, improving device performance. Nevertheless, optimizing thickness, defect density, metal contact work function remains insufficiently explored, despite its potential to enhance power conversion efficiency. In this study, a numerical simulation was performed using SCAPS-1D (version 3.3.10) identify optimal parameters...
Abstract Greenhouse gas emissions are caused by human activities, one of which is the manufacturing process, main driver global warming. The machining process a common practice in sectors such as aerospace and automotive. Based on latter, this research focuses understanding testing an alternative way to make economically sustainable process. This study reports performance tool life analysis under dry settings, cutting speed calculation considers tooling costs. Developing design experiment...
Inverted perovskite solar cells (PSCs) have gained much attention due to their low hysteresis effect, easy fabrication, and good stability. In this research, an inverted cell ITO/PEDOT:PSS/CH3NH3PbI3/PCBM/Ag structure was simulated optimized using SCAPS-1D version 3.3.10 software. The influence on the device of parameters, including thickness, total defect density, series shunt resistances, operating temperature, are discussed analyzed. With efficiency increased from 13.47% 18.33%. Then, a...
Using a theory of homogenization that consists in the discretization inclusion binary phononic crystal small volumes, which material parameters can be expanded Fourier series, we have determined dependence effective elastic as function frequency. In particular, frequency all elements constitute tensors stiffness (moduli elasticity) and density was analyzed for 1D conformed materials whose main characteristic is high contrast between their properties. this dynamic case homogenization, it...
Gray cast iron (GCI) is a common material in the automotive industry due to its mechanical characteristics, which change primarily for materials employed foundry and cooling rate of material. According workpiece, cutting tool parameters are analyzed improve machining increment lifetime tools. In this research, process an component using ceramic coated carbide tools were study case, effect that they have on age strengthening GCI wear was studied. Both inserts capability machine with rough...
With the application of a homogenization theory, based on Fourier formalism (which provides efficient and exact formulas by which to determine all components effective stiffness mass density tensors, valid in regime large wavelengths), new approach calculate quasi-static response three-dimensional solid-solid phononic crystals is reported. The derived this work for calculating elastic parameters show dependence, terms summations over vectors, reciprocal lattice discretization volume...
DFT (Density Functional Theory) calculations were carried out to evaluate the chemical interaction of CO (carbon monoxide) and NO (nitrogen molecules onto nanographenes (NGs)n n=1-6 units; thus, for this range adsorption process is exhibited, excepting n=5 desorption favored. On other hand, dioxide titanium clusters (TiO2)n n=1-4 proposed adsorb molecule, atop parallel sites considered attach molecule these four possible isolated models (C1-C4) are generated as result interaction,...
Tool selection is relevant because a wide variety of materials exhibit different machinability behaviors. life during manufacturing commonly associated with productivity. Insert developers have been using coatings on cutting tools to enhance their performance, chemical vapor deposition (CVD) and physical (PVD) being the two most used techniques. This study analyzed tool wear mechanism by machining AISI D2 steel inserts TiAlN/TiN PVD TiCN/Al2O3 CVD as layers deposited carbide substrate. The...
A homogenization theory that can go beyond the regime of long wavelengths is proposed, namely, a still valid for vectors waves near edge first zone Brillouin. In this paper, we consider displacement vector and magnetic induction fields have averages in volume cell associated with values electric edges cell, so they satisfy Maxwell's equations. Applying Fourier formalism, explicit expressions were obtained case photonic crystal arbitrary periodicity. one-dimensional (1D) crystals, tensor...
