The use of transparent conductive films with textured structures improves the short-circuit current density, but it is difficult to form a uniform electron transport layer. We previously developed a method to form a uniform electron transport layer in a short time by combining PFNs and colloidal SnO2. In this experiment, we verified the effect of changing the counter anion; uniform electron transport layers could be deposited with PFN-I instead of PFN.
