نویسندگان
چکیده
Cadmium telluride (CdTe) nanoparticles were deposited on glass substrates coated by indium tin oxide (ITO) and fluorine doped (FTO) as transparent conducting films at 200 °C under pressure of 2×10-5 mbar. The thickness the prepared was about nm. structure, optical, electrical, morphological properties layers analyzed x-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, current-voltage (IV) characterization, scanning electron microscopy (SEM), respectively. XRD patterns show cubic structure CdTe thin film both ITO FTO substrates. preferred orientation also changed from (111) for substrate to (220) substrate. crystallite size in these orientations 23.41 34.84 nm, thin-film transmittance spectra determined using UV-Vis spectroscopy wavelength range 200-1200 optical energy bandgap calculated be 1.60 1.63 eV, I-V curve shows more electrical conductivity compared ITO. surface morphology images homogeneity uniformity surface.

متن کاملTantalum nitride films integrated with transparent conductive oxide substrates via atomic layer deposition for photoelectrochemical water splitting.
Tantalum nitride, Ta3N5, is one of the most promising materials for solar energy driven water oxidation. One significant challenge of this material is the high temperature and long duration of ammonolysis previously required to synthesize it, which has so far prevented the use of transparent conductive oxide (TCO) substrates to be used which would allow sub-bandgap light to be transmitted to a ...

In this paper, the performance of the buffer layer of Cadmium Telluride (CdTe) thin film solar cell was optimized using SCAPS software. At first, five different buffer layers including CdS, In2S3, ZnO, ZnSe and ZnS with variable thicknesses from 10 to 100 nm have been replaced in the structure of the solar cell and it has been observed. As the thickness of the buffer layer is increased, the eff...
