Theoretical study of  ZnS/CdS bi-layer for thin-film CdTe solar cell
The performance of CdTe solar cells is strongly limited by the thickness of CdS window layer. A higher short-circuit current density might be achieved by decreasing the thickness of CdS layer as a result of reducing the absorption losses that take place in this layer. However, it is difficult to obtain uniform and pin-hole free CdS layers thinner than 50 ... إقراء المزيد

Effect of the synthesis conditions on the structural, morphological and optical properties of Bi2Te2.7Se3 nanoparticles
Beside their promising utility as thermoelectric generators, Bi2Te3 and related compounds have several applications in electronic and optoelectronic devices. In this work, Bi2Te2.7Se0.3 nanoparticles (NPs) were successfully prepared via physical vapor deposition technique at different conditions of flow rate and temperature. The x-ray diffraction patterns show that, the NPs crystallize in a rhombohedral crystal structure with preferable growth along the ... إقراء المزيد

Optical and photocatalytic properties of sol gel nano particles Co:TiO2 thin films
ABSTRACT Co-TiO2 nanoparticle thin films were synthesized by sol-gel method. The structural properties of the synthesized sample were studied using FTIR, XRD, and TEM. XRD confirmed the presence of double-phase anatase/rutile for the TiO2 nanoparticles. Effect of annealing temperature and exposure to microwave energy on the optical properties were studied for transparent conductive oxide (TCO) application. The optical energy gap ... إقراء المزيد

Investigation of the structural, optical and electrical transport properties of n-doped CdSe thin films
ABSTRACT THIN FILMS OF (CDSE)90(IN2O3)10, (CDSE)90(SNO2)10 AND (CDSE)90(ZNO)10 HAVE BEEN GROWN ON GLASS SUBSTRATES BY THE ELECTRON BEAM EVAPORATION TECHNIQUE. IT HAS BEEN FOUND THAT UNDOPED AND SN OR IN DOPED CDSE FILMS HAVE TWO DIRECT TRANSITIONS CORRESPONDING TO THE ENERGY GAPS EG AND EG + DUE TO SPIN–ORBIT SPLITTING OF THE VALENCE BAND. THE ELECTRICAL RESISTIVITY FOR N-DOPED CDSE ... إقراء المزيد

Properties of transparent conducting oxides formed from CdO alloyed with In2O3
Abstract The structure, optical and electrical properties of transparent conducting oxide films depend greatly on the methods of preparation, heat treatment, type and level of dopant. Thin films of (CdO)1−x(In2O3)x have been grown by electron beam evaporation technique for different concentrations of In2O3 (x=0, 0.05, 0.1, 0.15 and 0.2). Increase of doping led to increased carrier concentration as derived from ... إقراء المزيد
