Dye-sensitized solar cell (DSSC) has been expected to be an alternative to the conventional silicon solar cell due to simple manufacturing process and low fabrication cost [1]. The condition of dye-coating process is one of the important factors in the fabrication process. In order to enhance dye adsorption on the TiO2 layer of large scale DSSC, the condition was optimized for the dye-coating process such as temperature, time and concentration of base on references paper [2].
In this work, we report dye-coating conditions to enhance the efficiency of which was made in the area of 0.25, 6 and 15 Cm2. The experiment shows the optimal coating condition with the coating temperature of 70 ℃, the dye concentration of 10 mM and the coating time of 3 min. We confirmed that the energy conversion efficiencies of DSSCs with area 6Cm2 (3X2) and 15Cm2(3X5) were about 5% and 4.5%, respectively.
