a-d, Comparison of (a) PCE, (b) FF, (c) Jsc, and (d) Voc for pristine and IPA α-FA0.94Cs0.06PbI3-based devices. The Voc, Jsc, FF, and PCE were extracted from 36 devices’ reverse scan J-V curves. e, J-V curves of our champion pristine α-FA0.94Cs0.06PbI3 device. The detailed performance parameters are inserted in the figure. f, EQE spectra and integrated current (Jsc) of the IPA α-FA0.94Cs0.06PbI3 device. By integrating the EQE over the AM 1.5 G standard spectrum, the integrated Jsc of IPA α-FA0.94Cs0.06PbI3 device is 26.27 mA cm−2.
