In this study, aluminum induced texturing (AIT) technique is used to increase light absorption in thin film by way of increasing the portion of the diffuse transmitted light (haze). For this purpose, various AIT process parameters such as starting aluminum thicknesses, annealing temperature and time, etching time, etchant's concentrations, and temperature of etching are known to affect the final texture. We have investigated the effect of aluminum thickness and etching time on AIT process while keeping the other parameters fixed. Our results show that by changing initial aluminum thickness and etching time, it is possible to control surface morphology of glass substrate and the resulting optical diffuse transmittance. In addition, diffuse transmittance is increased over the visible range of solar spectra and total absorption by a‐Si:H is increased.

Influence of thermal annealing on microstructural, morphological, optical properties and surface electronic structure of copper oxide thin films AKSOY, FUNDA; AKGÜL, GÜVENÇ; Yıldırım, Nuray; Ünalan, Hüsnü Emrah; Turan, Raşit (Elsevier BV, 2014-10-15) In this study, effect of the post-deposition thermal annealing on copper oxide thin films has been systemically investigated. The copper oxide thin films were chemically deposited on glass substrates by spin-coating. Samples were annealed in air at atmospheric pressure and at different temperatures ranging from 200 to 600 degrees C. The microstructural, morphological, optical properties and surface electronic structure of the thin films have been studied by diagnostic techniques such as X-ray diffraction (X...
Effects of optical design modifications on thermal performance of a highly reflective HfO2/SiO2/TiO2 three material coating OCAK, M.; Sert, Cüneyt; Okutucu-Ozyurt, T. (Springer Science and Business Media LLC, 2018-02-01) Effects of layer thickness modifications on laser induced temperature distribution inside three material, highly reflective thin film coatings are studied with numerical simulations. As a base design, a 21 layer coating composed of HfO2, SiO2 and TiO2 layers of quarter wave thickness is considered. First, the laser induced temperature distribution in this base design is obtained. Then the layer thicknesses of the base design are modified and the corresponding temperature distributions in four alternative no...
Aluminum Induced Glass Texturing (AIT) on Soda-Lime, Borosilicate, Alkali-Free and Silica Glass For Thin Film Solar Cell Applications Ünal, Mustafa; Günöven, Mete; Tankut, Aydın; Sökmen, İlkay; Turan, Raşit (2015-12-10) Texturing of glass substrate is an alternative novel method for light trapping, which to enhance the absorbed light by way of increasing the diffused transmittance (haze) so that the amount of absorbed light will be increased instead of texturing transparent conductive oxide (TCO). In this study, aluminum induced texturing (AIT) technique is used to texture different type of glasses to see the effect of the chemical composition on surface morphology and optical properties. Improvement in haze values as well...
Effect of oxygen plasma on surface properties and biocompatibility of PLGA films Hasırcı, Nesrin; Endoğan Tanır, Tuğba; Kızıltay, Aysel; Hasırcı, Vasıf Nejat (2010-06-01) In this study, poly(D, L-lactide-co-glycolide) (PLGA) films were prepared by solvent casting method and the surfaces of the films were modified by application of oxygen plasma. A radio frequency (RF) generator working at 13.56 MHz was used to create plasma, and powers at different levels changing between 20 and 300 W were applied. The variations in chemistry, topography and surface free energy (SFE) of the films were investigated by electron spectroscopy for chemical analysis (ESCA), atomic force microscopy...
Effect of particle polydispersity on particle concentration measurement by using laser Doppler anemometry Ayranci, Isil; Pinguet, Guillaume; Escudie, Dany; Selçuk, Nevin; Vaillon, Rodolphe; Andre, Frederic (2007-08-01) Measurement of particle concentration by laser Doppler anemometry (LDA) is studied on a vertical air jet seeded by a powder disperser with controlled particle and air flow rates. Particle arrival rate is utilized to retrieve particle number densities from conventional LDA operation. The effect of polydisperse nature of the particles is assessed. Comparisons between measured and estimated particle number densities suggest that only a certain portion of the particle population with a particle size to fringe s...
