Article Preview

This study provides a simple and low cost method to deposit TiO2 nanoporous thin films onto the titanium mesh substrate. The flexible titanium mesh is adopted as electrodes where a novel structure of dye-sensitized solar cell (DSSC) is fabricated. The titanium mesh owns many advantages such as low resistance, cheap and high temperature tolerance. The photoanode is fabricated while the Ti mesh immersed into the alcohol solution of nanopowder of TiO2 (P25). For a better adhesion, several treatments against the titanium mesh are carried out. The photovoltaic parameters of various DSSC are discussed through the observations of TiO2 nanoporous thin films. The alcohol solution of N719 dye is used to sensitized the photovoltaic and the electrolyte is a mixture of 0.5 M LiI, 0.05 M I2 and 0.5 M 4-tert-butyl-pyridine in 3-methoxypropionitrile. With a Xenon illuminating, a flexible cell with Jsc=2.9 mA, Voc=0.5 V and F.F =0.68, η=1.02 % is obtained.
