Dye-sensitized solar cells compared to other conventional solar cells have relatively less efficiency but for preparing and making easy and low-cost among other solar cells is taken into consideration. Most of the work in this area is done to increase the efficiency of solar cells. One way to increase the efficiency relate to the anode of dye-sensitized solar cells. In this study, titanium oxide deposited on conductive glass is used as anode. Surface modification was carried out on titanium oxide layer using electrical discharge of argon plasma sheath, effect of titanium dioxide layer thickness and the method of using argon plasma sheath have been studied. The function of dye-sensitized solar cells for two sample, one without affecting of plasma sheath and the other with using argon plasma sheath have been compared. The aim of this study is to create a regular surface of deposited titanium oxide on the Nano scale. With doing this, solar cell losses will be reduced and thus solar cell efficiency can be increased. To evaluate the data, the imaging scanning electron microscopy (SEM) and electrical voltage - flow curves have been used.
