(color online) (a) Nyquist plot of PSCs without and with dual NPs at DC bias of V = 0.4 V under 1 sun illumination. (b)–(d) Series resistance, resistance of the selective contacts, and recombination resistance of PSCs without and with dual NPs are presented, respectively. Equivalent model is included in the insert of panel (b).
