Abstract

This paper is concerned with the synthesis, characterization, and electrochemical properties of all solid state dye-sensitized solar cells (SSDSSCs) with a dense TiO₂ layer. The dense TiO₂ layer, which was prepared from titanium hydroxide and titanium tetra isopropoxide precursor, has been characterized by X-ray diffraction, scanning electron microscopy. The experimental results showed that the TiO₂ layer formed using titanium hydroxide precursor with a thickness of about 100 nm was composed of crack free anatase-phase. The dense TiO₂ layer is found to improve the short circuit current density (Jsc), leading to enhancement in the conversion efficiency (η) of the SSDSSCs from 2.92 to 3.60%.
