Author Correction: Surface in situ reconstruction of inorganic perovskite films enabling long carrier lifetimes and solar cells with 21% efficiency

In the version of this article initially published, y-axis tick marks and units for intensity were not included in Fig. 1a,b.In addition, text was missing after the second sentence of the "Film characterization" section of Methods: "Time-resolved PL spectra were measured by F900 spectrometer with a 375 nm pulsed laser (EPL-375).In the TRPL spectra test, a 377 nm picosecond laser (Edinburgh Instruments EPL-375) was used to excite both the control and target samples.The excitation pulse width was 55 ps with a repetition rate of 200 KHz.The laser spot size was 0.05 cm 2 and the fluence was around 0.5 μJ/cm 2 .The TRPL was conducted in the mode of time-correlated single photon counting (TCSPC), which is commonly used to test the fluorescence decay lifetime from 10 ps-50 μs."The Methods and Fig. 1 have been updated in the HTML and PDF versions of the article.
