Fig. 5 — Photovoltaic characterization: a J-V curves of the devices with different passivation layers in comparison to the control device without any treatment, with a scan rate of 10 mV/s b Maximum power tracking of the same device, c) IPCE spectra and calculated photocurrent integrated over the standard AM 1.5 G solar emission. In agreement to the J-V data no change in the spectra is observed, and d J–V metrics of perovskite devices with different treatment in comparison to the control
