Abstract

In this study, the synthesis and characterization of cobalt doped zinc oxide (Co:ZnO) nanocomposite materials were achieved using hydrothermal method from zinc nitrate and Cobalt (II) chloride precursors. Zinc oxide nanostructures were doped with cobalt in different dopant concentrations. The Co concentration was varied from 0.5 to 1.5 mol % in ZnO crystalline structure. Cobalt doped ZnO materials were analysed using XRD, SEM and EDX. Also DSSC performances of cobalt doped ZnOs were studied. Best efficiency was obtained with 1% doped Co:ZnO as 3.48 mA/cm2 of short circuit photocurrent density, 600 mV of open circuit voltage, 0.56 of filling factor, 1.17 of overall conversion efficiency.

Özet

Bu çalışmada Fotovoltaik Üretim Teknolojileri için Kobalt doplu ZnO nanomateryali hidrotermal proses kullanılarak sentezlenmiş ve üretilen fotovoltaiklerin verimleri değerlendirilmiştir. Kobalt doplu ZnO nanomateryaller katkılama oranı % 0.5 den % 1.5’e kadar değişen verimlerde sentezlenmiştir. Katkılanan kobalt doplu ZnO nanomateryaller XRD, SEM ve EDX teknikleri ile analizlenmiştir. SEM görüntüleri kobalt doplu ZnO nanoyapıların morfolojilerinin nanorod düzeyinden nanotabaka morfolojisine değişimini ispatlamıştır. EDX analizleri kobalt doplu ZnO yapıların oluşumunu kanıtlamıştır. Fotovoltaik enerji dönüşüm verimleri analizlenmiştir. Bu çalışmada % 1 kobalt katkılama oranı için 3.48 mA/cm2 kısa devre akımı, 600 mV açık devre voltajı, 0.56 dolum faktörü ve % 1.17 verim ile en yüksek verim rapor edilmiştir
