Fig. 4From: Orientation-Controllable ZnO Nanorod Array Using Imprinting Method for Maximum Light Utilization in Dye-Sensitized Solar Cells a Photocurrent density versus voltage characteristics and b Nyquist plots of the DSCs with different photoanode configurations. The EIS measurement was performed under the dark at −0.7 V. The inset shows open-circuit voltage decay curves right after turning off illuminationBack to article page
