We demonstrate the fabrication of nano-sized surface textured crystalline silicon by a metal-assisted electroless etching method with nitric acid added as the hole injection agent. This method generates randomly shaped cone-like structures that offer a clear advantage over nanowires by enabling straightforward passivation with standard techniques. Average reflection values as low as 3% have been achieved. Optimizing the thickness of anti-reflective coatings, the doping depth and the screen-printed metal firing process increases the short circuit current of the cell by 0.82 mA/cm(2) over the reference cells, which had a pyramidal texture without nano texturing.

Nano patterning of AISI 316L stainless steel with Nonlinear Laser Lithography: Sliding under dry and oil-lubricated conditions Gnilitskyi, Iaroslav; Rotundo, Fabio; Martini, Carla; Pavlov, Ihor; Ilday, Serim; Vovk, Evgeny; Ilday, Fatih Omer; Orazi, Leonardo (2016-07-01) Femtosecond laser-based Nonlinear Laser Lithography (NLL) was applied to AISI 316L stainless steel, which requires surface modification to achieve satisfactory tribological behaviour. NLL advances over the well-known Laser Induced Periodic Surface Structures (LIPSS) in terms of uniformity and long-range order of high speeds, over large areas. A galvanometric scanner head was used for an high production rate. Dry and lubricated sliding tests, considering different orientations of the nanotexture showed that ...
Multi-crystalline silicon solar cells with metal-assisted nano-texturing using HNO3 as hole injection agent Es, Fırat; Baytemir, Gulsen; Kulakci, Mustafa; Turan, Raşit (2016-12-01) In this study, metal-assisted etching (MAE) with nitric acid (HNO3) as a hole injecting agent has been employed to texture multi-crystalline silicon wafers. It was previously proven that addition of HNO3 enabled control of surface texturing so as to form nano-cone shaped structures rather than nanowires. The process parameters optimized for optically efficient texturing have been applied to multi-crystalline wafers. Fabrication of p-type Al: BSF cells have been carried out on textured samples with thermal S...
FABRICATION AND CHARACTERIZATION OF SERS SUBSTRATES VIA LASER INDUCED PHOTOCHEMICAL SURFACE ROUGHENING OF SILICON Akbıyık, Alp; Bek, Alpan; Department of Physics (2022-6-10) In this thesis, Surface-Enhanced Raman Spectroscopy (SERS) substrates are fabricated using laser assisted chemical etching of silicon as a surface nanostructuring technique. As a novel method of control over the structuring parameters, the incident laser illumination is spatially modified via a Digital Micromirror Device (DMD) that enable fast and uniform fabrication of complex structures. Onto the photochemically nanostructured silicon surfaces, silver and gold films are deposited by thermal evaporation or...
Shape memory polymer composites containing carbon based fillers Şengör, İrem; Bayram, Göknur; Köysüren, Özcan; Department of Chemical Engineering (2013) The aim of this dissertation was to produce shape memory polymer nanocomposites using diglycidyl ether of bisphenol A (DGEBA) epoxy resin and isophorone diamine based cyclo-aliphatic curing agent. The polymer matrix was modified with aliphatic and aromatic monomers namely, neopentyl glycol diglycidyl ether (NGDE) and resorcinol diglycidyl ether (RDE). In the formation of composites, carbon black and carbon nanotubes were used separately and also together as hybrid filler. All samples were subjected to mecha...
Optimized spacer layer thickness for plasmonic-induced enhancement of photocurrent in a-Si:H Saleh, Z. M.; NASSER, H; ÖZKOL, E; GÜNÖVEN, M; Abak, Musa Kurtuluş; Canlı, Sedat; Bek, Alpan; Turan, Raşit (2015-10-24) Plasmonic interfaces consisting of silver nanoparticles of different sizes (50-100 nm) have been processed by the self-assembled dewetting technique and integrated to hydrogenated amorphous silicon (a-Si:H) using SiNx spacer layers to investigate the dependence of optical trapping enhancement on spacer layer thickness through the enhancements in photocurrent. Samples illuminated from the a-Si:H side exhibit a localized surface plasmon resonance (LSPR) that is red-shifted with the increasing particle size an...
