A new type of photovoltaic materials, which are designed on the base of In6S7 single crystals using silver and gold metals to construct Ag/In6S7/Au point contacted photocells, are reported and discussed. The influence of the driving electric field on the performance of the device was tested. The current density-electric field dependence curve reflected a space charge limited photocurrent effect being dominant in the field region of 1.0-4.3 V/cm. In addition, the In6S7 photocell short circuit and loaded current dependencies on the excitation intensity were measured. The short circuit current was observed to exhibit exponential trap distribution effect and supralinear recombination at low and high illumination intensities, respectively. The device displays a current density of 0.5 mA/cm(2) for excitation intensity of 76 klux. When loaded, it displayed a stable power dissipation curve. Such behavior reflects the novelty of these types of cells for future application.

Modelling and performance analysis of linear fresnel collector for process heat generation for ice cream factory in Konya Singh, Rahul; Baker, Derek Keıth; Tarı, İlker; Department of Mechanical Engineering (2017) In this thesis, a linear Fresnel collector has been designed to supply solar heat for industrial process. Firstly, optical analysis using ray tracing is done to determine the effects of collector’s parameters, such as height of receiver, mirror width and profile, gap between adjacent rows and slope deviation. Afterwards, one-dimensional thermal model is presented which predicts surface temperatures of receiver components and heat loss. The results obtained from both optical and thermal studies are then benc...
Optimization of metalization in crystalline silicon solar cells Demircioğlu, Olgu; Turan, Raşit; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2012) Production steps of crystalline silicon solar cells include several physical and chemical processes like etching, doping, annealing, nitride coating, metallization and firing of the metal contacts. Among these processes, the metallization plays a crucial role in the energy conversion performance of the cell. The quality of the metal layers used on the back and the front surface of the cell and the quality of the electrical contact they form with the underlying substrate have a detrimental effect on the amou...
Production of High-Performance CdZnTe Crystals Grown by THM for Radiation Detection Applications Ünal, Mustafa; Balbaşı, Özden Başar; Karaman, Mehmet Can; Genç, Ayşe Merve; Parlak, Mehmet; Turan, Raşit (2022-01-01) © 2022, The Minerals, Metals & Materials Society.CdZnTe crystals are the perfect candidate to be used in room temperature x-ray and gamma-ray detection systems. Production of detector-grade crystals, on the other hand, is challenging due to the unique properties of the CdZnTe. CdZnTe crystals are soft-brittle materials and have high ionicity of bonds that makes the growth process challenging. Among several growth techniques, the travelling heater method (THM) is a preferred growth method to obtain high-qual...
Gold nanostar @ iron oxide core-shell nanostructures: synthesis, characterization, and demonstrated surface-enhanced Raman scattering properties Nalbant Esentürk, Emren (2013-01-01) Iron oxide-coated gold nanostars are produced by first synthesizing gold nanostars (ca 150 nm), then introducing a polyvinylpyrollidone coating followed by reducing iron(II) and iron(III) salts on the nanoparticle (NP) surface. Morphological and chemical composition characterizations of these composite nanomaterials were performed via field-emission transmission electron microscopy/energy dispersive spectroscopy studies. The analysis revealed that the majority of the NPs had coating of approximately 1-5 nm ...
Hydrothermal synthesis of TiO₂ nanostructures for photocatalitic and photovoltaic applications Erdoğan, Nursev; Öztürk, Abdullah; Park, Jongee; Department of Metallurgical and Materials Engineering (2017) Titanium dioxide (TiO2) nanostructures with different crystal structures and various morphologies were synthesized by hydrothermal process to utilize them in photocatalytic and photovoltaic applications. The investigations were conducted in three different sets of systematic experimental studies. The first set of experiments was based on the synthesis of TiO2 nanostructures in the presence of strong sodium hydroxide (NaOH) catalyzer. Temperature and molarity of NaOH were kept constant while hydrothermal rea...
