Light-induced electroless plating (LIEP) is an easy and inexpensive method that has been widely used for seed layer deposition of Nickel/Copper (Ni/Cu)-based metallization in the solar cell. In this study, material characterization aspects of the Ni seed layer and Ni silicide formation at different bath conditions and annealing temperatures on the n-side of a silicon diode structure have been examined to achieve the optimum cell contacts. The effects of morphology and chemical composition of Ni film on its electrical conductivity were evaluated and described by a quantum mechanical model. It has been found that correlation exists between the theoretical and experimental conductivity of Ni film. Residual stress and phase transformation of Ni silicide as a function of annealing temperature were evaluated using Raman and XRD techniques. Finally, transmission line measurement (TLM) technique was employed to determine the contact resistance of Ni/Si stack after thermal treatment and to understand its correlation with the chemical-structural properties. Results indicated that low electrical resistive mono-silicide (NiSi) phase as low as 5 m Omega.cm(2) was obtained.

An Alternative Metal-Assisted Etching Route for Texturing Silicon Wafers for Solar Cell Applications
Es, Fırat; Kulakci, Mustafa; Turan, Raşit (2016-03-01)
Metal-assisted etching (MAE) can be used to form antireflective and light-trapping structures on crystalline silicon solar cells. This method has been widely used to form nanowires and nanoholes on their surfaces. In this study, the MAE technique with additional hole-injection mechanisms has been investigated to form surface nanostructures with various shapes. The effect of each chemical's percentage, as well as the etching time, has been studied on the surface geometry and optical performance. The average ...
Optimization of Selective Electrophoretic Deposition and Isostatic Compression of Titania Nanoparticles for Flexible Dye-Sensitized Solar Cells
Kocaoglu, Bahadir Can; Icli, Kerem Cagatay; Özenbaş, Ahmet Macit (2016-04-01)
Flexible photoanodes on PEN/PET based substrates for dye-sensitized solar cells (DSSC) by using electrophoretic deposition (EPD) method for the formation of titania nanoporous layer with titania nanoparticles (P-25) were produced. Considering commercially available titania nanoparticles containing both anatase and rutile phases, the undesired rutile nanoparticles, for DSSC applications, were almost eliminated from the coatings by selective pH adjustment of the EPD solutions without any binders. The coating ...

The decoration of metal nanoparticles (MNPs) by the self-organized mechanism of dewetting is utilized as a suitable method for plasmonic interface integration to large area full-scale solar cell (SC) devices. Reflection measurements are performed on both flat and textured silicon (Si) SCs in order to investigate the local plasmonic resonances of the MNPs. The effects of particle size and thickness of silicon nitride (Si3N4)anti-reflection coating layer are investigated by reflection measurements and the shi...
Theoretical and thermal characterization of a wideband perfect absorber for application in solar cells
Rufangura, Patrick; Sabah, Cumali (2016-12-01)
This paper suggests a metamaterial (MTM) absorber structure to be used for efficiency improved solar cell. The proposed MTM absorber consists of the topmost three concentric circular ring resonators, and a ground metal plane sandwiched to the top layer with a dielectric spacer. Numerical simulation and theoretical (interference theory) studies on the proposed design show a wideband with near-perfect (>99%) absorption response in the visible frequency region of the solar spectrum. Thermal characterization of...
A sol-gel derived AgCl photochromic coating on glass for SERS chemical sensor application
Volkan, Mürvet; Vo-Dinh, T (Elsevier BV, 2005-05-13)
A new optically translucent material has been prepared that acts as a substrate for surface-enhanced Raman spectroscopy. This material is a silica matrix, synthesized by the sol-gel method and containing in situ precipitated AgCl particles which serve as precursors for nanoparticles of elemental silver. Reduction of AgCl to silver nanoparticles is achieved by UV irradiation. The SERS-active medium was distributed on glass supports (cover glass slips, 0.5 turn thick), hence producing thin, sturdy, and optica...
