Thin films of copper based chalcopyrite absorber materials are attracting the attention of many researchers because of their favorable optoelectronic properties and good stability makes them suitable for photovoltaic and optoelectronic device applications. These compounds are particularly suitable for making p-n hetero-junctions with the II-VI compounds. Therefore, the utilization of I-III-VI2 group of chalcopyrite semiconductors has been reported in the literature for application in thin film solar cells. In this work, the quaternary structure Cu-Ag-In-Se (CAIS) that belongs to the ternary semiconducting I-III-VI2 materials family formed by occupying the Cu sites alternatively with Ag has been investigated. CAIS thin films were prepared by using a magnetron DC/RF sputtering system, and CIS and Ag targets were used in the deposition process of the CAIS thin films in stacked layer formation to get a homogenous film structure. In fact, the work has been particularly concentrated on the wire-shaped formations on the CAIS film surfaces for the forms of as-deposited and thermally annealed at different temperatures. The characterizations of the thin films were done by X-ray diffraction (XRD), and also scanning electron microscope (SEM) equipped with energy dispersive X-ray analysis (EDXA) detector facility. The surface characteristics were investigated by SEM measurements and the observed nanostructures were detailed. Moreover, the complementary characterization of the films includes transmission and reflection measurements for optical; room temperature resistivity measurements and temperature dependent conductivity for electrical analysis.

Bayraklı, Özge; Güllü, Hasan Hüseyin; Parlak, Mehmet (2016-10-02)
Thin Film Solar Cell has received a considerable attention in the photovoltaic industry. While the efficiency of thin film amorphous silicon is about %14, the efficiency of Cu(In,Ga)Se2 (CIGS) thin film based solar cells ,is very popular in the recent year, reached the value of %20. But CIGS based solar cells have some constraints such as its extensive and large scale production in terms of availability of its constituent elements. On the other hand, Kesterit based solar cells such as Cu2ZnSnSe4 (CZTSe) hav...

Yavaş, Hakan; Durucan, Caner; Department of Metallurgical and Materials Engineering (2012)
Indium tin oxide (ITO) thin films have been used as transparent electrodes in many technological applications such as display panels, solar cells, touch screens and electrochromic devices. Commercial grade ITO thin films are usually deposited by sputtering. Solution-based coating methods, such as sol-gel however, can be simple and economic alternative method for obtaining oxide films and also ITO. In this thesis, “ITO sols” and “ITO nanoparticle-incorporated hybrid ITO coating sols” were prepared using indi...
