Abstract Thermally stimulated luminescence of the X-ray irradiated CdSSe-doped borosilicate glases have been studied. The two well defined temperarure maxima discovered for total thermoluminescence intensity, as well as the thermoluminescence dependence on the nanocrystal size and X-ray dose are discussed. More >

Abstract The method for producing power by integrating a beta source to semiconductors junction’s devices is called as betavoltaic energy conversion. [1]. In this study by using Monte Carlo (MC) method to simulate the distribution of electron- hole pairs (EHP) generated at each point in the cell under bombardment of ⁶³ Ni source for betavoltaic cell then the result of that Monte Carlo simulation will be used in the modelling and simulation of a betavoltaic cell CdS/CdTe heterojunction and their characteristics.

Abstract Photocatalytic degradation of methyl red dye using Mn(5%) doped CdS nanoparticles was studied.Mn doped CdS nanoparticles was synthesized by microwave assisted solvo thermal method where the chemicals used wereCadmium Acetate [(CH₃COO)₂Cd, H₂O], Manganese Chloride [MnCl₂.2H₂O] and Sodium Sulfide [Na₂S.xH₂O]. X-Ray diffraction(XRD) analysis was carried out in order to analyze the structural dimensions of the synthesized nanoparticles and the average crystallite size has been calculated at the full width half maximum (FWHM) of the diffraction peaks using Debye-Scherer equation and it was found to be around2.3nm. FTIR spectra analysis was done in order to analyze different functional and… More >

Abstract The characteristics of a single solar cell made by CdS thin film deposition on a silicon glass substrate were estimated using simulation models in this study. An aluminum electrode was attached to a silicon wafer to produce a heterojunction, and the indium fingers were fashioned into another electrode and connected directly to the CdS layer.
Simulation steps were performed using PV*SOL 3.0 software package and bias points (I_SC, V_OC ) models. In addition to the use of advanced programs such as MATLAB software (Shell SQ150 PV module), Mathcad 2000 program, and Origin Lab 2019 program.Simulation programs More >

Abstract In this work, CuO thin films about the synthesis of the thin films are prepared on glass substrate using spray pyrolysis technique at room temperature different annealing times in temperature 450 0 C.In order to study the effect of annealing times onthe structural, optical and electrical properties.XRD analysis has shown that films with a polycrystalline structurehave a(Monoclinic) structure.In addition, the crystallite phase CuO increases with increasing of annealing temperature.Moreover, with a preferred orientation along (002) peak.The optical properties confirmed that the elaborated films have a transmittance of 70%. We have found that the band gap More >

Abstract The photoelectret effect in composite heterostructures consisting of polar (fluorinecontaining) and non-polar (polyolefins) polymers - high density polyethylene (HDPE), low density polyethylene (LDPE), F42, F2-ME and the inorganic phase A^II B^VI (CdS, ZnS) has been studied. It has been established that the difference in photoelectret potentials in a given volume share of the inorganic phase mainly depends on the polarity of the polymer matrix. A possible mechanism of the photoelectret effect formed under the combined action of a strong electric field and light in these composites. It has been experimentally established that the potential barrier formed More >

Abstract The purpose of the study is to determine the best technique for etching ZnO thin films. ZnO is deposited on the glass substrate using a radio frequency sputtering equipment. To etch the ZnO thin film, hydrogen peroxide (H₂O₂) concentrations of 10%, 20%, and 30% are utilised, with etching times of 30 and 60 seconds. The optical band gap is lowered after a specific quantity of etching, which shows that the film's crystallinity quality has improved. The impact of various ZnO thicknesses on the sample's optical properties is investigated using OPAL 2 simulator. In comparison to other More >

Abstract The development of sulfide solid electrolyte is limited by the interface instability with lithium metal and low ionic conductivity. In this work, the effects of doping SiS₂, SnS, ZnS and MnS on the ionic conductivity and interfacial stability of sulfide electrolytes are systematically investigated. The conductivity of Li₇P_2.9Sn_0.1S_10.7Br_0.3 solid electrolyte was as high as 1.67 mS cm^-1 . Furthermore, it is found that the critical current density was proportional to the resistivity of the doping element. The critical current density of the electrolyte was significantly increased by electronically insulating Si doping, reaching 0.858 mA cm^-2. . More >
