【 摘 要 】

TiO$_2$ nanoparticles were synthesized by a facile wet chemical synthesis using triethylamine (TEA) as a surface passivating agent. The role of TEA on the formation and functional properties of TiO$_2$ nanoparticles were investigated.Particle agglomeration was restricted and nanoparticle size was limited to 5 nm by passivating the amine molecule. Photoanodes were fabricated by spray deposition method using synthesized TiO$_2$ nanoparticles. The efficiency of 5.91%was obtained by the dye-sensitized solar cells.
