Abstract

© 2021 National Institute of Optoelectronics. All rights reserved.In this study, for the production of flexible photoanodes, a binder-free TiO2 paste has been prepared. The photoelectrodes fabricated with this paste at low temperature have been achieved a very good contact compared to the results prepared by conventional high temperature procedures. These flexible photoanodes have been sensitized with Ruthenizer N719 dye at 24 hours and this flexible photoanode and Pt counter electrode have been combined. The characteristic values of Jsc, Voc, FF and conversion efficiency (n) have been obtained 20.9 mA/cm2, 671 mV, 0.57, and 7.95 % respectively for the flexible dye sensitized solar cell (DSSC).
