Abstract

Tin oxide has been demonstrate to possess outstanding optoelectronic properties such as optical transparency and high electron mobility, therefore, it was successfully utilized as electron transporting layer in various kind of solar cells. In this study, for the first time, highly dispersible SnO2 nanoparticles were synthesized by microwave-assisted non-aqueous sol-gel route in an organic medium. Ethanol dispersion of the as-prepared nanoparticles was used to cast an uniform thin layer of SnO2 without the aid of aggregating agent and at low temperatures. Organohalide perovskite solar cells were fabricated using SnO2 as electron transporting layer. Morphological and spectroscopic investigations, in addition to the good photoconversion efficiency obtained evidenced that nanoparticles synthesized by this route have optimal properties such small size and crystallinity to form a continuous film, furthermore, this method allows high reproducibility and scalability of the film deposition process.
