a J–V curves of control and K2SnO3-modified single-junction Sn-Pb PSCs. b The corresponding EQE curves of the Sn-Pb PSCs. c Steady-state power output (SPO) efficiency of the best-performing Sn-Pb PSC at a bias voltage of 0.76 V. d PCE statistics of control and target devices, with 20 devices measured for each type. e Long-term stability of unencapsulated control (initial efficiency: 20.24%) and target (initial efficiency: 22.63%) single-junction Sn-Pb cells stored in an N2-filled glovebox. f Mott-Schottky curves, (g), ideality factor characteristics, and (h), J-V curves of hole-only devices without and with K2SnO3 incorporation.
