Fig. 3: PV performance of the control and target PSCs.
The control devices use PEAI and the target devices CBz-PAI as interface passivator. a, An illustration of the device architecture of the target PSCs. b, J–V curves of the control and target PSCs devices measured under reverse scan direction. The comparison of forward and reverse scans are shown in Supplementary Fig. 21. c, The stabilized maximum power output of the control and target PSCs devices. d, IPCE spectrum and integrated current of the control and target PSCs devices. e, Histogram of average PCE values of the control and target devices. f, Light intensity dependence of VOC. The ideality factor nid is calculated from the slope of the linear fit of the semilogarithmic plot. q, electron charge; K, Boltzmann constant; T, Kelvin temperature.
