Fabrication of Flexible Dye-Sensitized Solar Cells by Pressurization-Transfer Technique

Abstract:

In this study, the flexible dye-sensitized solar cell is fabricated by pressurization-transfer technique, which involves assembling TiO₂ films on ITO/PEN flexible substrates via high temperature sintering. During the experiment, we change not only the film thickness and structure of TiO₂ but also the dye of working electrodes. The surface morphology of TiO₂ films are examined by field emission scanning electron microscopy (FE-SEM). The analyses of UV-Vis show that N3 dye could be adsorbed on the TiO₂ thin films, and the TiO₂ thin film with scattering layer has better absorption than that of without scattering layer. The current-voltage of the DSSC is illuminated by the solar simulator whose incident light intensity was 1000 W/m². These results indicate that the best efficiency of flexible dye-sensitized solar cell with high-temperature sintering TiO₂ film and scattering layer is 6.13%.
