Nanofluid Boiling and Sintering for Dye-Sensitized and Perovskite Solar Cell Application
TiO2 nanoparticles are often used in the production of Dye-Sensitized and Perovskite solar cells due to their unique properties. These nanoparticles come in differing phases and morphologies. The purpose of this research is to apply nanofluid boiling method to deposit TiO2 nanoparticles on FTO substrate and then investigate the effects of ramping rate and maximum temperature on characteristics of deposited nanoparticles on FTO substrate. It was observed that thickness of deposited nanoparticles depends on boiling time and concentration of nanofluid. The thickness of deposited nanoparticles changed linearly with nanofluid concentration and boiling period. Furthermore, the effects of different sintering strategies were investigated. The results indicated that the characteristics of a sintered sample is dependent on sintering strategies. As ramping rate decreased, the deposited nanoparticles fused and become more organized. Similar, effects were observed as maximum temperature increased from 150 °C to 550 °C.
