Abstract
In this paper, the surface of electrodes used in solar cells was roughened using wet etching method among surface texturing method, and after surface treatment, dye sensitive solar cell using TiO2 oxide semiconductor was produced. The surface spectroscopic properties of surface treated electrodes were analyzed according to etching time, and by evaluating the electrical properties of TiO2 dye-sensitized solar cells produced according to etching time, the study on improving the efficiency of solar cells according to surface treatment was conducted. As a result, solar cells that etched the electrode surface for 10 minutes could see an improvement of about 27.46[%] over their existing efficiency.
