The transmittance and sheet resistance (R-sh) of AgNWs/hcPEDOT electrodes were controlled by varying the spin-coating cycle of AgNW films. Variations in cell-performances including the power conversion efficiency (PCE), the short-circuit current density (J(sc)), and the fill factor (FF) that resulted from varying the R-sh of AgNW-based films were systematically studied. With reducing R-sh of transparent electrodes, the FF and the series resistance were continuously improved, but the OSC with the highest FF showed a low J(sc) value due to the decrease in transmittance with increasing AgNW density. As a result, an optimum OSC showed a PCE of 2.699%, which is a slightly low PCE value compared with ITO-based OSCs. These results indicate that the cell-performance of OSCs is highly dependent on R-sh of the AgNW-based electrode and that a trade-off between R-sh and transmittance of transparent electrodes should also be considered to perfectly replace the conventional ITO and to achieve higher device-efficiency.
