Copper Sulfide Catalyzed Porous Fluorine-Doped Tin Oxide Counter Electrode for Quantum Dot-Sensitized Solar Cells with High Fill Factor

<div>Nyquist plots for porous-FTO/CuS electrodes for various FTO thicknesses. Panels (a)(1), (a)(2), (a)(3), and (a)(4) are the results for FTO thicknesses of 5, 10, 15, and 20 <i>μ</i>m, respectively. FTO thickness dependence on the resistance is shown in panel (b). CuS SILAR cycle for all samples was fixed at 20 times. Black dots in panels (a)(1) to (a)(4) indicate the data recorded under each decade of the frequency.</div>
