1. Introduction

EIS spectra were measured under illumination and at applied bias voltage equivalent to the open-circuit voltage (V oc) of the device in the dark over the frequency range of 0.1 to 10 5 Hz using a 10 mV amplitude AC signal. Impedance spectra were fitted to an equivalent circuit model using ZView software (Scribner Associates Inc.).
