Özet

In this study, zinc oxide (ZnO), which has attracted attention due to its applications in dye sensitive solar cells, has been used as electrode in DSSC. ZnO nanostructures were produced by hydrothermal synthesis method. Polyvinylpyrrolidinone (PVP) was used as the surfactant in the production of ZnO nanostructures and sodium hydroxide (NaOH) was used as the reactant. In order to determine morphological features of synthesized ZnO nanostructures, Scanning Electron Microscopy (SEM) and X-ray diffraction method were used to determine structural features. For dye-sensitive solar cell production, firstly TiCl4 thin film coated on fluorine doped tin oxide (FTO) glass and then ZnO nanostructures coated by a doctor blade method on the TiCl4 layer. ZnO film, which is used as electrode in DSSC fabrication is immersed in ruthenium based paint solution at different temperatures (at room temperature and 80 °C). ZnO films were kept in a ruthenium-based dye solution for 16 hours to allow dye absorption. In order to create the DSSC structure, the synthesized electrolyte was dropped on the ZnO electrode and the platinum (Pt) coated glass with a small hole in the middle was clipped together with the counter electrode. I-V measurements of the produced solar cells were studied by using a standard solar simulator of 1 Sun intensity with AM 1.5 filter. The effect on different parameters such as open circuit voltage, short circuit current, filling factor , and power conversion efficiency of DSSCs were analysed.
