Yüksek Verimli PERC Güneş Pilleri için Pikosaniye Atımlı Lazer ile Lazer Doping Yoluyla Seçici Emitör Oluşumu

In this study, we develop a POCl3 diffusion recipe so that we obtain a thicker phosphosilicate glass layer for laser doping. The formation of a laser doped selective emitter is achieved by utilizing an industrial-type picosecond pulsed laser operating at 532 nm (green) wavelength () and pulse repetition rate (frep) of 1 MHz. To demonstrate the selective emitter concept, sheet resistance reduction of the laser processed region after tube furnace diffusion is provided. In addition, produced samples are metalized and the difference of contact resistivities of both homogenous emitter and laser doped emitter is shown. By applying a moderate amount of heat accumulation on the surface, specific contact resistivity of the laser doped region is reduced to around 3 mΩ.cm2. We report process details and results in this paper.

Processing and characterization of high density tungsten-nickel-iron alloys
Çalışkan, Necmettin Kaan; Bor, Şakir; Durlu, Nuri; Department of Metallurgical and Materials Engineering (2013)
In the present study, processing of W-Ni-Fe alloys by liquid phase sintering technique has been investigated. Effect of sintering atmospheres (hydrogen and vacuum), tungsten content altering from 90 to 97 wt.%, Ni/Fe ratio varied from 2 to 4 and post sintering treatments (heat treatment and swaging) on the microstructure and mechanical properties of W-Ni-Fe alloys have been analyzed. Liquid phase sintered alloys were characterized by mechanical tests, electron microscopy and XRD studies, thermal analyses an...
Characterization of ultra-fine grained steel samples produced by high pressure torsion via magnetic barkhausen noise analysis
Bayramoğlu, Sadık; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2009)
High Pressure Torsion (HPT) is one of the most widely used severe plastic deformation methods which enable to obtain a crack free ultra-fine grained bulk material with improved mechanical properties like increased strength and toughness. In the process, a disc shaped sample is pressed between two anvils and deformed via surface friction forces by rotating one of the anvils. The aim of this study is to nondestructively characterize the variations in the deformation uniformity of the severely deformed steel d...
Effects of granulated blast furnace slag trass and limestone fineness on the properties of blended cements
Delibaş, Tuğhan; Yaman, İsmail Özgür; Hoşten, Çetin; Department of Cement Engineering (2012)
The aim of this research was to determine the effects of the fineness of different mineral additives on loss on ignition, heat of hydration, physical, mechanical and chemical properties of blended cements. For that purpose, portland cement clinker was replaced with granulated blast furnace slag (GBFS), natural pozzolan (NP) and limestone (L) at 6%, 20% and 35% replacement levels. Blended cements containing GBFS and NP were ground to a fineness of 3000, 5000 and 6000 cm2/g. Cements containing L were ground t...
Synthesis of liquid crystalline copolyesters with low melting temperature for in situ composite applications
Erdoğan, Selahattin; Bayramlı, Erdal; Department of Polymer Science and Technology (2011)
The objective of this study is to synthesize nematic-thermotropic liquid crystalline polymers (LCP) and determine their possible application areas. In this context, thirty different LCP’s were synthesized and categorized with respect to their fiber formation capacity, melting temperature and mechanical properties. The basic chemical structure of synthesized LCP’s were composed of p-acetoxybenzoic acid (p-ABA), m-acetoxybenzoic acid (m-ABA), hydroquinone diacetate (HQDA), terephthalic acid (TPA) and isophtha...
Production and characterization of high performance al – fe – v – si alloys for elevated temperature applications
Sayılgan, Seda; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2009)
In the present study, the powder metallurgy was evaluated as a technique to produce high performance Al – 8Fe – 1.7V – 7.9Si (wt%) alloys for elevated temperature applications and the role of powder particle size range and extrusion ratio in the microstructural and mechanical properties of the extruded alloys was investigated. For this purpose, an air atomization method was employed to produce powders of the high temperature alloy and after that the produced powders were sieved and cold compacted. The compa...
