Texture, morphology and photovoltaic characteristics of nanoporous F:SnO2 films

Abstract

The nanoporous F:SnO2 materials have been prepared through the controlled hydrolysis of fluoro(2-methylbutan-2-oxy)di(pentan-2,4-dionato)tin followed by thermal treatment at 400-550°C. The main IR features include resonances at 660, 620 and 540 cm-1. From the TG-DTG result, three main mass losses of 6.5, 13.3 and 3.8 at 81, 289 and 490°C are observed between 50 and 650°C yielding a final residue of 76.0%. The size of Sn O2 nanoparticles rose from 5 nm to 10-12 nm as the temperature of thermal treatment is increased from 400 to 550°C.
