Özet
In this study, TiO2, which provides the highest efficiency today, was used as the photoelectrode, and 1-naphthalenetic acid (NAA) was added to the N719 dye as an coadsorbent. Since the absorbing effect of NAA is known, it was aimed to provide a more effective insulating barrier for electron transfer back to the electrolyte from the TiO2 conduction band by grafting the two absorbers together into the dye-sensitized solar cells (DSSCs), packing the sensitizer more tightly than it was. By examining different dye-coadsorbent ratios (10:0, 10:1, 10:2, 10:3 N719 and NAA), power conversion efficiencies were obtained as 4.12, 5.91, 3.25, 2.42, respectively. As a result, a 43.45% increase in power conversion efficiency was observed with the 10:1 ratio N719/NAA mix.
