It has come to the authors attention that incorrect versions of Figures 1, 2, and 4 were inadvertently used during the final stages of manuscript preparation. The correct figures are shown below. This does not affect the interpretation of data or the conclusion given in this Research Article.
Illustrations of sustainably eliminating on comprehensive defects in MAPbI3 by Fc. a) Dominate defects at A-, B- and X-sites of MAPbI3 perovskite. b) Proposed sustainable recovery mechanism on comprehensive defects in MAPbI3 perovskite via a two-cyclical 4-step chain-reaction strategy, in which the red cycle represents redox potentials of Fc/Fc+ pair transferring charges from I0 (X-site) to Pb0 (B-site) defects, and blue cycle means intermediated FcPbI3 perovskite fixing MA (A-site) defect back to MAPbI3. Both cycles can recover Fc as a sustainable manner. The 4-step chain reactions (i-iv) are confirmed by corresponding characterizations (c–f), respectively. c) 1H NMR spectra of Fc and FcI in dimethyl sulfoxide (DMSO)-d6. d) UV/Vis absorption spectra of FcI and PbI2 in dimethylformamide (DMF) solution. e) Single crystal packing diagram of 1D FcPbI3 perovskite, orange polyhedrons are Fc+ cations and grey polyhedron are 1D Pb-I frameworks. f) XRD spectra of pristine FAPbI3 and that exposed in MA gas environment, generating MAPbI3 perovskite. g) DFT calculated dissociation energies of 1D FcPbI3 and 3D perovskites. h) The schematic diagram of 1D to 3D perovskite conversion.
Thin-film XRD spectra and high-resolution XPS spectra. a) XRD spectra. b) Pb 4f region in XPS spectra, c) I 3d region in XPS spectra, of MAPbI3 perovskite films as reference (ref.) and with different anionic Fe salts (FeFc2, FeCl2, FeCl3, Fe(acac)2, Fe(acac)3, respectively) as additives in 1 % molar ratio.
Device performances, reproducibilities, and durabilities of CsFAMA PSCs with and without Fc additive. a) J–V characteristic curves of champion devices via reverse and forward scans at rate of 10 mV s−1, measured under the solar simulator of AM 1.5G, device parameters are in the inset table. b) IPCE spectra and their integrated current densities. c) Steady-state current density and PCE. d) Nyquist plots of PSCs with different content of Fc at a potential bias of 1.0 V, and frequency range from 106 to 100 Hz, in the dark. The inset is the equivalent circuit model. e) J–V curves of the best PSCs with different content of Fc. f) Efficiency distribution histograms of 60 independent PSCs based on different content of Fc, each spot is averaged from 60 values (4 independent cells on 15 devices). Long-term stability tests of PSCs based on CsFAMA perovskite absorber with the incorporation of 1 % Fc additive at different conditions: g) in nitrogen glovebox without any encapsulation. h) Under continuous 85 °C heating on hotplate, 50 %±10 % RH wetting in environment box, and 1-sun (1000 W m−2 LED) illumination.
