Synthesis and Characterization of Ti
Ti1−x Sn x O2 nanoparticles with different Ti/Sn ratios (x=0–0.1 and 1.0) were successfully synthesized by the coprecipitation method, and its nanotubes were prepared from low‐temperature chemical synthesis in NaOH solution. The influence of Sn dopant on the structures and the photovoltaic properties as dye‐sensitized solar cells for these nanostructured TiO2 were investigated. The photovoltaic performance of Ti1−x Sn x O2 nanoparticle photoelectrodes degraded with the addition of Sn. However, regardless of the absence of Sn, a conversion efficiency of TiO2 nanotubes made from Ti1−x Sn x O2 (x=0–0.05) nanoparticles increased depending on the x value and reached to 5.98% for x=0.05.
