Processes of Titanium-Dioxide Colloids for Working Electrodes of Dye-Sensitized Solar Cells

Abstract:

New titanium-dioxide (TiO₂) colloids composed of nano-crystalline TiO₂ and polydimethylsiloxane (PDMS) have been developed for use in the working electrodes of dye-sensitized solar cells (DSSCs). The surface morphology and electrical characteristics of the TiO₂ colloid electrodes were studied. The analysis of the surface morphology of the TiO₂ colloids was conducted by an atomic force microscope (AFM) and a field-emission scanning electron microscope (FE-SEM). The photovoltaic characteristics of the TiO₂ colloids with different compositions were investigated. The TiO₂ content of the colloids determined the photovoltaic conversion ability of DSSCs. Colorful colloids were implemented by adding pigments to the TiO₂ colloids. The processes of the TiO₂ colloids demonstrated the advantages of simple fabrication and low cost. The flexible property of the TiO₂ colloids showed great potential for application in flexible optoelectronics.
