Fabrication of titanium dioxide thin film for dye- sentitized solar cell using Improved electrostatic inkjet device

Abstract

Dye-sensitized Solar Cell (DSC) is one of the noteworthy devices due to its superior design and low cost process. However, there is a drawback in low conversion efficiency. We are controlling the structure of titanium dioxide thin film used for dye sensitized solar cell for high efficiency by using electrostatic ink jet method which is printing technology. In the currently used electrostatic inkjet method, the large droplets are stacked on the substrate by gravity. In this study, to remove the large droplets nozzle orientation and positional for the substrate are controlled, and we have succeted to form an uniform thin films.
