제목 Effects of TiCl4:SrCl2-modified Photoelectrodes on the Performance of Dye-Sensitized Solar Cells
초록 The surface of TiO2 photoelectrodes coated on F-doped SnO2 (FTO) was modified by soaking it in a TiCl4:SrCl2 mixed aqueous solution with various molar ratios and then calcining to produce the TiCl4:SrCl2-treated TiO2 photoelectrode (Ti:Sr-TiO2/FTO). The highest power conversion efficiency (PCE) was obtained from dye-sensitized solar cells (DSSCs) with Ti:Al(7:3)-TiO2/FTO, which were prepared from the mixed solution with the molar ratio of 7:3 (TiCl4:SrCl2). PCE of DSSCs with Ti:Al (7:3)-TiO2/FTO was improved by ca. 11.3%, compared to that of the reference device with Ti:Al (10:0)-TiO2/FTO due to an enhancement in short-circuit photocurrent and open-circuit voltage.
