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...
In this research work, we present the synthesis and characterization of four different TiO2 structures, such as nanotubes, nanocavities, nanosheets assembled on nanocavities nanobowls prepared by electrochemical anodization using organic electrolytes. After synthesis, structures were thermally annealed to pass from amorphous phase anatase phase, which is one most important crystalline due its high photocatalytic activity stability. The unique morphology topography studied scanning electron...
The ability to plan a multiple-target path that goes through places considered important is desirable for autonomous mobile robots perform tasks in industrial environments. This characteristic necessary inspection monitor the critical conditions of sectors thermal, nuclear, and hydropower plants. also useful applications such as service at home, victim rescue, museum guidance, land mine detection, so forth. Multiple-target collision-free planning topic has not been very studied because...
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...
Abstract In the present article gamma radiation–induced graft copolymerization of acrylamide (AAm) onto poly (3-hydroxybutyrate) (PHB) has been carried out by simultaneous irradiation method. The effect different solvents on reaction was investigated. P(HB-g-AAm) thus synthesized were characterized Fourier transform-infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electron micrography (SEM), swelling behavior, and nuclear magnetic...
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...
