However, highest recorded efficiencies for Sb2Se3 solar cells are still lower than ideal. Exploring antimony selenosulfide (Sb-2(SxSe1-x)(3)) to increase device performance is one option because some features of alloyed Sb-2(SxSe1-x)(3) depend on composition such as bandgap and band position. In this study, two-step process was used to grow Sb-2(SxSe1-x)(3) thin films. In the first stage, Sb2Se3 thin films were deposited on soda lime glass substrates using direct current magnetron sputtering technique. In the second stage, Sb2Se3 thin films were exposed to sulfurization process in a quartz ampoule to obtain Sb-2(SxSe1-x)(3) thin films. Characterization results showed that morphological, optical, and structural properties of Sb-2(SxSe1-x)(3) thin films grown by presented method were highly dependent on amount of sulfur in the films. By the adjustment of the S/S + Se atomic ratio, Sb-2(SxSe1-x)(3) absorber materials with suitable bandgap, favorable orientation and compact morphology can be obtained for photovoltaic applications.Article Citation - WoS: 8Citation - Scopus: 8Development of Zto/Ag Transparent Electrodes for Thin Film Solar Cells(Springer, 2022) Türkoğlu, Fulya; Köseoğlu, Hasan; Ekmekçioğlu, Merve; Cantaş, Ayten; Özdemir, Mehtap; Aygün, Gülnur; Özyüzer, LütfiThis article presents the optimization of Zinc Tin Oxide/Silver/Zinc Tin Oxide (ZTO/Ag/ZTO) multilayers to implement them in thin film solar cells as transparent electrodes. To achieve improvements on the performance of these transparent multilayers, effect of Ag and ZTO thicknesses, and position of Ag layer within the multilayer were investigated. Electrical and optical characterization of these multilayers revealed that reduced sheet resistance and improved optical transmittance can be acquired for solar cells by the optimization of thin film thicknesses and position of the Ag within the multilayer. The improvement of the electrical and optical behavior of the ZTO/Ag/ZTO structures enabled figure of merit (FoM) values up to 69.69 × 10–3 Ω−1. The performance of our multilayer electrodes was also compared with ITO and AZO electrodes. The obtained results suggest that fabricated multilayer electrodes can be a good choice for thin film solar cells.
