Influence of Growth Temperature on TiO2 Nanostructures by Hydrothermal Synthesis

Abstract

Titanium dioxide (TiO2) shows a great interest in solar cell application due to its morphology and crystalline structure. Moreover, it is an affordable compound that could make solar cells more economical than traditional silicon solar cells. In this study, one-step hydrothermal method is demonstrated to synthesis TiO2 nanorods/nanoflowers morphology on different hydrothermal reaction temperature. Increasing the reaction temperature could influence the formation of highly crystalline rutile phase of titania thin film. Moreover, the growth mechanism under different reaction temperatures has pronounced effects on the preferred orientation, morphologies and sizes of the structure. The results serve as guidance principle in preparing high quality solar cell specifically in heterojunction thin film fabrications.

Fabrication and Characterization of p-Cu2O on n-TiO2 Layer by Electrodeposition Method for Heterojunction Solar Cells Development

“…However, these peaks low and weak intensity, which indicates that Cu2O did not fully grow on the TiO2 nanorods layer. The crystallite size of Cu2O phase was calculated by Scherrer equation [20]. It can be observed that the crystallite sizes of Cu2O increased when the deposition time increased as proven by the FWHM values as shown in Table 1.…”
