  1. Photovoltaic parameters for various DSSCs fabricated using different counter electrodes and the fitted impedance parameters extracted from fabricated symmetric cells are as follows: Jsc, short-circuit current density; V oc , open-circuit voltage; FF, fill factor; R s , series resistance; R ct , charge transfer resistance.
