In this work, both planar and textured, industrial scale (156mmx156mm) single-crystalline silicon (Si) solar cells have been fabricated using zinc oxide (ZnO) nanorods as antireflection coating (ARC). ZnO nanorods were grown in a few minutes via hydrothermal method within a commercially available microwave oven. Relative improvement in excess of 65% in the reflectivity was observed for both planar and textured Si surfaces. Through ZnO nanorods, effective lifetime (eff) measurements were presented to investigate the surface passivation property of such an ARC layer. ZnO nanorods increased the eff from 9 to 71s at a carrier injection level of 1015cm3. Increased carrier lifetime revealed the passivation effect of the ZnO nanorods in addition to their ARC property. 33% and 16% enhancement in the photovoltaic conversion efficiency was obtained in planar and textured single-crystalline solar cells, respectively. Our results reveal the potential of ZnO nanorods as ARC that can be deposited through simple solution-based methods and the method investigated herein can be simply adapted to industrial scale fabrication.

Highly Efficient Room Temperature Synthesis of Silver-Doped Zinc Oxide (ZnO:Ag) Nanoparticles: Structural, Optical, and Photocatalytic Properties Yildirim, Ozlem Altintas; Ünalan, Hüsnü Emrah; Durucan, Caner (Wiley, 2013-03-01) Synthesis of silver-doped zinc oxide (ZnO:Ag) nanoparticles through precipitation method has been reported. The synthesis was conducted at room temperature and no subsequent thermal treatment was applied. ZnO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), fourier transmission infrared spectroscopy (FTIR), and ultraviolet-visible (UVVis) spectroscopy. Detailed crystallographic investigation was accomplished through ...
Comparison of Natural Halloysite With Synthetic Carbon Nanotubes in Poly(lactic acid) Based Composites Erpek, Canan Esma Yeniova; ÖZKOÇ, GÜRALP; Yılmazer, Ülkü (Wiley, 2017-11-01) The objective of this study is to compare the mechanical properties, structure and degradability of the nanocomposites prepared with tubular nanofillers, halloysite (HNT) and carbon nanotube (CNT) in poly(lactic acid) (PLA), and thermoplastic polyurethane (TPU) toughened PLA (T-PLA) matrices. In the PLA matrix, CNT increased, whereas HNT decreased the tensile strength with increasing filler content. Also, the elongation at break and impact strength decreased with increasing CNT content, but these properties...
Light induced changes in the density of states of a-Si:H Özdemir, S.; Öktü, Özcan (Elsevier BV, 1989-1) Thermally stimulated conductivity (TSC) and photoconductivity were measured before and after light irradiation in hydrogenated amorphous silicon (a-Si:H) films prepared by glow discharge technique. It was observed that even medium-level of exposure to light decreased both the TSC and photoconductivity by nearly an order of magnitude over a temperature range between ∼ 100 and 300 K. From these measurements the density of gap states (DOS) between the dark Fermi level and conduction band mobility edge were cal...
Enhanced methylene blue removal efficiency of TiO2 embedded porous glass Ertus, E. Burak; Vakifahmetoglu, Cekdar; Öztürk, Abdullah (Elsevier BV, 2021-02-01) A porous glass (PG) embedded with titanium dioxide (TiO2) was produced via impregnation of the PG with Titanium (IV) Isopropoxide solution followed by crystallization. N-2 sorption analyses revealed that the specific surface area (SSA) and total pore volume of the PG reached to 358 m(2)/g and 0.370 cm(3)/g, respectively. The adsorption capacity of methylene blue (MB) for the glasses was measured in the dark, instead the photocatalytic MB removal efficiency was evaluated by the degradation of MB under UV lig...
Cobalt borate phosphate, Co-3[BPO7], synthesis and characterization Yılmaz, Ayşen; Bu, XH; Kizilyalli, M; Kniep, R; Stucky, GD (Elsevier BV, 2001-02-01) Single crystals of Co-3[BPO7],I were obtained by boron flux method and characterized by single-crystal diffraction data. The compound crystallizes in the monoclinic space group Cm with 9.774(2), b = 12.688(2), c = 4.9057(8) Angstrom, beta = 119.749(2)degrees; V= 528.20(15) Angstrom (3); Z = 4. The structure consists of Co in trigonal bipyramids, square pyramids, and distorted octahedra. Polyhedral Co centers, triangular B centers, and tetrahedral P centers are joined together to form a three-dimensional net...
