Abstract:
Nowdays titanium dioxide is used in different applications because of their good electrical properties, optical stability and cost savings. According to their different nanoscale TiO2 structures, It has been determined that 1D structures such as nanorods, nanotubes and nanowires has more better properties than the other structures, including enhancing electron transport and create an offered directional way of transporting of the electron. However, the grain boundaries in polycrystalline TiO2 nanowires or nanotubes cause electron scattering or trapping, which limit their application in optoelectronics. From these TiO2 structures, TiO2 nanorods have special importance because of less defects related barriers blocking the charge carrier transport that may effect on transporting properties. the length of nanorods is a key factor influencing the charge collection efficiency. So in this paper hydrothermal synthesis of TiO2 has been studied as it can be used as an electron transport layer instead of materials such as meso-porous TiO2 or TiO2 nanoparticles. For this purpose different factors has been studied such as time and temperature of synthesis and concentration of raw materials. Temperatures of 130,150 and 170C and time of And 12 hours have been chosen. At last with studying and evolution of morphology and structure and carrier transport longs without recombination, the optimized state of synthesis have been offered.
