  1. Abbreviations: Cdl, double-layer capacitance; Eff., energy-conversion efficiency; FF, fill factor; Jsc, short-circuit photocurrent density; Rct, charge-transfer resistance; Rs, series resistance; Voc, open-circuit voltage.
  2. *The photocurrent–voltage measurements were carried out under an air mass 1.5 G one sun intensity of 100 mW cm−2. During the measurement, the samples were covered with a black mask with an aperture to prevent extra light coming through the lateral space. The active areas of the samples were about 0.250 cm2 for all of the samples.
