Abstract
Many researchers are engaged on dye-sensitized solar cell (DSSC) because DSSC is cheap and easy to fabricate. However efficiency of DSSC is not so high. The main purpose of the study on the DSSC is to improve the efficiency. Former studies were focused on the shape and chemical characteristics of titania and pigments, the efficiency was relatively increased. Because best thickness will depend on kind of titania paste, fabrication method that can change the thickness easily should be developed. We have been developing new inkjet technology that name is PELID (Patterning with Electrostatically-Injected Droplet) method. When the strong electric field is applied to a nozzle, small droplets are ejected by the electrostatic force. In this paper, we have been applying the PELID method to pattern titania layer on FTO glass. We investigated the thickness in case that the patterning time is changed because the efficiency depended on the thickness.
