Abstract:

TiO2 nanofibres have been synthesized by a simple hydrothermal process in 10M NaOH. TEM images have shown that nanofibres measuring average length 500nm and diameter 10nm were formed by this method. XRD analysis indicated strong anatase peaks with crystal orientation in the direction (101) with slight rutile peaks appearing at 5000C calcinations temperature. Thin films prepared from the nanofibres had thickness varying from 4.5 – 5.5μm. The films were used to fabricate complete dye sensitised solar cells with Ruthenium complex dye as sensitizer. I-V characteristics yielded Voc and Jsc of 0.46V – 0.58V and 0.16mA/cm2 – 4.5mA/cm2 respectively under standard illumination of 100mW/cm2 (using a halogen lamp and data acquired using Keithley 2400 Source Meter® controlled by LabVIEW® software).
