Different aspects of silicon anodization are discussed. First, concerning the controversy of mobile ions during the anodic oxide growth, the inward motion of the anion is thought the most probable alternative and then a growth mechanism based on the diffusion of hydroxyl ion from the electrolyte to the oxide-silicon interface is established. The growth rate, apparently complex, is interpreted in the light of this model by introducing and justifying a temperature rise during anodization

Effects of different laser modified surface morphologies and post-texturing cleanings on c-Si solar cell performance Radfar, Behrad; ES, FIRAT; Turan, Raşit (Elsevier BV, 2020-01-01) Performance of crystalline Silicon solar cells depends on numerous factors. One key factor is a surface structure which can restrict electrical and optical properties due to recombination of generated carriers and reflection of incident light. Surface texturing reduces reflection from a flat surface which increases absorption of light. Anisotropic alkaline etchants are commonly used for texturing mono-crystalline Silicon wafers which produce pyramid structures on the surface. Because of randomly oriented cr...
Effect of Laser Parameters and Post-Texturing Treatments on the Optical and Electrical Properties of Laser Textured c-Si Wafers RADFAR, Behrad; ES, FIRAT; NASSER, Hisham; AKDEMİR, Ozan; Bek, Alpan; Turan, Raşit (2018-03-21) Surface plays a crucial role in the performance of crystalline silicon (cSi) based solar cells as it affects both electrical and optical properties. To minimize reflection from the flat surface and thus improve light trapping, the cSi wafers must be textured. For mono-cSi cells, anisotropic alkaline etchants are commonly utilized to create pyramids on the surface. However, this method is not viable for multi-crystalline silicon (mc-Si) wafers due to the presence of different and random crystallographic orie...
Effect of annealing on the mechanical properties of pla parts produced by fused filament fabrication Aydın, Sencer; Özerinç, Sezer; Department of Micro and Nanotechnology (2021-9-01) Additive manufacturing has become a disruptive technology for the production of load bearing components in a wide range of applications. Fused filament fabrication (FFF) is among the most effective and economical techniques for the printing of polymeric parts. There are numerous thermoplastic materials suitable for FFF. Among these, Polylactic acid (PLA) is a renewable, sustainable and cost-effective alternative. For better utilization of PLA parts produced by FFF, there is a need to understand the structur...
Effect of Different Binders on Cyclic Performance of Si/C Anodes for Secondary Lithium-Ion Batteries Miser, Burcu; Livan, Pelin; Altınok, Sertaç; Eyövge, Cavit; Öztürk, Tayfur; Aydınol, Mehmet Kadri (2017-09-28) Silicon is a strong anode material alternative to graphite in terms of its high energy and power capacity. On the other hand, the insertion of lithium atoms per silicon atom has some cons. The full lithiation of silicon results in a 400 % increase in volume. This drastic volume change causes diffusion-induced stress, which may lead to fragmentation, disintegration due to fractures and bonding problems of the current collectors with active materials, which lead to significant losses in capacity, and hence, p...
Effect of intersegmental interactions on the morphology of segmented polyurethanes with mixed soft segments: A coarse-grained simulation study Yıldırım, Erol; Wilkes, G. L.; Yilgor, I. (2016-05-04) Segmented thermoplastic polyurethanes, polyureas and polyurethaneureas (TPU) based on a given hard segment and two chemically different soft segments display interesting microphase morphologies and thermal, mechanical and surface properties. In these systems the final TPU morphology is mainly controlled by the structure, amount and molecular weight of the soft segment oligomers and the nature and extent of specific intermolecular interactions between the mixed soft segments themselves and with the urethane ...
