제목 Influences of metal nitrates as a surface modifier on the performance of hybrid solar cells
초록 Metal nitrates were introduced on the TiO2 surfaces by soaking the TiO2 films into an aqueous metal nitrate solution. The resulting electrodes were applied to the photoelectrodes of dye-sensitized solar cells (DSSCs). The DSSC with the Zn(NO3)2-modified TiO2 electrode exhibited a short-circuit current (Jsc) of 12.77 mA/cm2 and an open-circuit voltage (Voc) of 626 mV, compared with a Jsc of 12.06 mA/cm2 and Voc of 584 mV for a reference device with a pristine TiO2 electrode. In contrast to the Zn(NO3)2-modified TiO2 electrode, the power conversion efficiency of the device with Cu(NO3)2-modified TiO2 was sharply decreased, due to an increased interfacial charge recombination.
