Investigation of electrical properties of dye sensitized solar cells based on thin film electrodes

Abstract

For electricity production with zero emission Dye-sensitized solar cells (DSSC) shows a great potential having a low cost fabrication solar cell devices. In this research, we have used two types of modified titanium dioxide (TiO 2 ) nanoparticles as photoanodes for DSSC, such as commercial TiO 2 paste, and synthesis TiO 2 paste. These TiO 2 compact layers were coated on FTO (Fluorine doped Tin Oxide) coated conductive glass substrates using doctor blade technique. Then, a freshly prepared solution of iodide - triiodide, and Ruthenium (II) dye (N 719 ), were used as electrolyte and the dye, respectively. A platinum (Pt) coated FTO was used as a counter electrode. The J-V characteristics for all the devices were obtained under light evaluating their performance and to calculate the power conversion efficiency.
