The purpose of this paper is to understand how to produce a thin layer of SnO2 semiconductor on Fluorinedoped Tin Oxide (FTO) glass for photovoltaic applications. SnO2 nanoparticles were produced by first chemically decomposing tin salts followed by an oxidation reaction. To improve the stability and uniformity of the deposited metal oxide nanoparticles in a film, the nanofluid boiling deposition method is recommended. In this research, nanofluid boiling is applied to deposit nanoparticles uniformly on FTO glass. A boiling device was fabricated to allow for the deposition of SnO2 nanoparticles using the nanofluid deposition method. For photovoltaic applications such as perovskite solar cells, the deposited nanoparticles on a conductive glass substrate are often sintered to form a thin-film, transparent semiconductor layer before depositing light absorbing materials. The sintering process has a significant impact on the characteristics of deposited nanoparticles, including electron transport property and the interfacial area between the semiconductor and perovskite materials. The objectives of this research are to deposit nanoparticles using the nanofluid boiling method, and to understand the effects of ramping rate, maximum temperature, and sintering period at the maximum temperature on the characteristics of the deposited nanoparticles. This research will also explain the difference between spin coating and nanofluid boiling approaches to deposit the nanoparticles on FTO glass.
