Oxide-based nanoparticles have been studied extensively due to their unique optical and passivation properties, which are significantly distinct from those of bulk materials. The present study aimed synthesize copper oxide through the co-precipitation method. adequate substitution sodium hydroxide (NaOH) into CuO is analyzed by different characterizations, i.e., X-ray diffraction (XRD), Scanning Electron Microscope (SEM), UV–visible spectroscopy (UV–visible), Fourier transform infrared...
Silicon based solar cells have been fabricated for single layer SiO2 and double SiO2/TiO2 antireflective coatings (ARC) using rf sputtering technique. The results were obtained with nontexturized surface of p-type mono-crystalline silicon (100) substrate compared the as-grown Si cell. Effect (SLAR) (DLAR) AR on performance cell characterized through electrical (AM 1.5G, 100 mW/cm2), optical morphological measurements. addition DLAR initiated 37% improvement in efficiency monocrystalline...
The proposed dyes demonstrated characteristics conducive to achieving high-power conversion efficiency (PCE) in dye-sensitized solar cells (DSSCs). Novel azo diverse anchoring groups, including carboxylic acid, diacid, biscarbodithiolic phosphonic and sulfonic were examined assess their impact on electronic optical properties within DSSCs. A computational investigation was conducted design evaluate charge transfer mechanisms using azo-pyrrole-based for DSSCs performed with the Gaussians 09...
Indium tin oxide (ITO) and titanium dioxide (TiO2) anti-reflective coatings (ARCs) were deposited on a (100) P-type monocrystalline Si substrate by radio-frequency (RF) magnetron sputtering. Polycrystalline ITO anatase TiO2 films obtained at room temperature (RT). The thickness of (60 to 64 nm) (55 60 was optimized, considering the optical response in 400- 1,000-nm wavelength range. characterized X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscopy...
Cu2ZnSnS4 (CZTS) thin films were deposited from a single cationic bath by Successive Ionic Layer Adsorption and Reaction (SILAR) method. Regular SILAR route for CZTS had the drawback of preferential adsorption copper tin cations in comparison with zinc. This resulted Cu3SnS4 (CTS) Cu2S phases rather than phase pure films. A modified route, separate Zn2+ ions, circumvented difficulty hence led to UV–visible absorption spectra showed coefficients ~ 104 cm−1 band gap 1.5 eV. Combined van der...
We report the gamma-ray (γ-ray) radiation-induced defects incurred by a monocrystalline Si solar cell. Capacitance–voltage (C–V) and dark current–voltage (I–V) characteristics were investigated from 1 kHz to 100 at room temperature. The Co60 activity used for γ-ray irradiation of cell was 24864.37 atom Bq. laboratory-made irradiated 2π solid angle 60 150 min. Results revealed that all output parameters, namely, short-circuit current, open-circuit voltage, fill factor, relative efficiency,...
This work focuses on the performance of Al-doped CdS quantum dot (QD)/TiO2 solar cells. The devices were analyzed through current-voltage and capacitance-voltage measurements. It was observed from analysis absorption spectra that TiO2 nanowires improve light Al doped QDs both in visible near infrared (NIR) range. Current-voltage characteristics curve CdS/TiO2 at different illuminations show decrease illumination (from 100 to 5 mW/cm2), affects voltage current correspondingly. Power-voltage...
