Özet

TiO2 nanorods (NRs) are successfully synthesized on fluorine-doped tin-oxide pre-coated glass substrates via hydrothermal technique. The effect of growth parameters on morphology of the synthesized NRs is investigated in detail. The results revealed that critical values for temperature, growth-time, acidity, and precursor concentration are required for the synthesis of well-aligned TiO2 NRs. Following the optimization of growth parameters, the well-oriented TiO2 NRS are decorated with a thin-sputtered layer of CdTe (CdCl2-treated) to form a third generation inorganic-sensitized solar cell. The power conversion efficiency associated with the constructed solar cell is found to be 0.42%, which is exactly 3.5 times larger than that obtained for the non-CdCl2-treated device structure. As a second part of this study, a Schottky-type Ag/TiO2 UV-photodetector is fabricated, which exhibited a drastic increase in photocurrent under UV-light exposure, with a responsivity of ∼3 A W−1 for 380 nm at −1 V.
