Article Citation - WoS: 42Citation - Scopus: 44Growth of Cu2znsns4 Absorber Layer on Flexible Metallic Substrates for Thin Film Solar Cell Applications(Elsevier Ltd., 2015) Yazıcı, Şebnem; Olgar, Mehmet Ali; Akça, Fatime Gülşah; Cantaş, Ayten; Kurt, Metin; Aygün, Gülnur; Tarhan, Enver; Yanmaz, Ekrem; Özyüzer, LütfiIn this work, Cu2ZnSnS4 (CZTS) absorber layers were fabricated using a two-stage process. Sequentially deposited Cu-Zn-Sn thin film layers on metallic foils were annealed in an Ar + S2(g) atmosphere. We aimed to investigate the role of flexible titanium and molybdenum foil substrates in the growth mechanism of CZTS thin films. The Raman spectra and X-ray photoelectron spectroscopy analyses of the sulfurized thin films revealed that, except for the presence of Sn-based secondary phases, nearly pure CZTS thin films were obtained. Additionally, the intense and sharp X-ray diffraction peak from the (112) plane provided evidence of good crystallinity. Electron dispersive spectroscopy analysis indicated sufficient sulfur content but poor Zn atomic weight percentage in the films. Absorption and band-gap energy analyses were carried out to confirm the suitability of CZTS thin films as the absorber layer in solar cell applications. Hall effect measurements showed the p-type semiconductor behavior of the CZTS samples. Moreover, the back contact behavior of these metallic flexible substrates was investigated and compared. We detected formation of cracks in the CZTS layer on the molybdenum foils, which indicates the incompatibility of molybdenum's thermal expansion coefficient with the CZTS structure. We demonstrated the application of the magnetron sputtering technique for the fabrication of CZTS thin films on titanium foils having lightweight, flexible properties and suitable for roll-to-roll manufacturing for high throughput fabrication. Titanium foils are also cost competitive compared to molybdenum foils. © 2015 Elsevier B.V.Master Thesis Fabrication and Characterization of Superconducting Bi2212 Bolometer for the Detection of Thz Waves(Izmir Institute of Technology, 2014) Kurt, Metin; Aygün Özyüzer, Gülnur; Özyüzer, LütfiSince terahertz (THz) waves can pass through materials like clothing, plastic, wood, ceramic, leather and without harm to the body, it can be used for characterization, detection and 3D imaging of these materials. THz application area expands day by day such as high-speed wireless communications, medical imaging, security in airports and shopping centres and detection of chemical and biological materials. Rapidly increasing applications of the electromagnetic waves (EM) in the under developed terahertz frequency (0.1-10 THz) range requires a well understandings of efficient terahertz wave detection. An intense, coherent and continuous electromagnetic wave source is obtained by High-Tc superconductor Bi2Sr2CaCu2O8+δ (Bi2212) single crystal. At the same time Bi2212 single crystal can detect THz waves in suitable conditions. Nowadays, different types of bolometers are used for detection of THz waves. But they have many limitations like slow response time which is the most significant problem and costly cryogenic spending. In this study, single crystal of Bi2212 is cleaved to layer by layer by scotch tape until the necessary is reached thickness. Afterwards, it is pasted on a sapphire substrate and the scotch tape is etched with the aid of chloroform solution and ultrasonic cleaner. After the crystal fabrication, the exact thickness of the crystal were obtained using atomic force microscopy. Then, the samples were annealed at 400oC for 1 hour in order to adjust the oxygen doping level and then deposited with 150 nm Au layer by thermal evaporation. Afterwards they were annealed again at 425oC for 30 minutes to decrease the contact resistivity. After clean room process, our log-periodic antenna design was formed on the crystal by using e-beam lithography and Ar-ion beam etching step by step. Finally, four probe wires were connected to the two contact paths and log-periodic antenna by silver epoxy. The temperature dependence of a-b axis resistivity (R-T) for Bi2212 single crystals were performed.Article Citation - WoS: 2Citation - Scopus: 2Comparison of Photocatalytic Properties of Tio2 Thin Films and Fibers(EDP Sciences, 2016) Özdemir, Mehtap; Kurt, Metin; Özyüzer, Lütfi; Aygün, GülnurEfficiency of solar panels degrades as a result of organic contamination such as airborne particles, bird droppings and leaves. Any foreign object on photovoltaic panels reduces the sunlight entering the absorbing surface of the solar panels. Since this leads to a major problem decreasing in energy production, solar panels should be cleaned. The self-cleaning method can be preferred. There are some methods to clean the surface of solar panels. Among the self-cleaning materials, TiO2 is the most preferable ones because of its powerful photocatalytic properties. In this study, photocatalytic TiO2 were produced in two different nanostructures: nanofibers and thin films. TiO2 nanofibers were successfully produced by electrospinning. TiO2 thin films were fabricated by reactive magnetron sputtering technique. Both TiO2 nanofiber and thin film structures were heat-treated to form TiO2 in anatase phase at 600 °C for 2 h in air. Then, they were evaluated by SEM analyses for morphology, X-ray diffraction (XRD) analyses for phase structures, X-ray photoelectron spectroscopy (XPS) for the chemical state and atomic concentration, and UV-spectrometer for photocatalytic performance. The results indicate that photocatalytic and transmittance properties of TiO2 thin films are better than those of nanofibers. Consequently, TiO2 based thin films exhibit better performance for solar cell applications due to the surface cleanliness.Article Citation - WoS: 60Citation - Scopus: 64Improvement of Optical and Electrical Properties of Ito Thin Films by Electro-Annealing(Elsevier Ltd., 2015) Köseoğlu, Hasan; Türkoğlu, Fulya; Kurt, Metin; Yaman, Mutlu Devran; Akça, Fatime Gülşah; Aygün, Gülnur; Özyüzer, LütfiThe effect of electro-annealing in vacuum and air on the optical and electrical properties of ITO thin films grown by large area DC magnetron sputtering was investigated. Moreover, the performances of the electro-annealed ITO thin films in vacuum and air were compared. Electro-annealing was performed by applying 0.75, 1.00, 1.25 and 1.50 A constant ac current to the ITO thin films. It was observed that the crystallinity of the films was better for the ITO thin films electro-annealed in vacuum. The changes in sheet resistance of electro-annealed ITO thin films with applied currents were detailed. The transmittance of the films increased for both electro-annealing in vacuum and air. A correlation between band-gap and resistivity for all of the electro-annealed thin films was observed.Conference Object Citation - Scopus: 1Cleo®/Europe - Eqec 2015, an Indium Tin Oxide Metamaterial Filter for the Terahertz Regime: Design, Fabrication and Characterization(Optical Society of America (OSA), 2015) Takan, Taylan; Nebioğlu, Mehmet Ali; Kurt, Metin; Demirhan, Yasemin; Özyüzer, Lütfi; Sabah, Cumali; Altan, Hakan[No abstract available]
