Erratum: Over 17% Efficiency Binary Organic Solar Cells with Photoresponses Reaching 1000 nm Enabled by Selenophene-Fused Nonfullerene Acceptors (ACS Energy Letters (2021) 6:1 (9−15) DOI: 10.1021/acsenergylett.0c02230)

Page 12. We have found errors in Figure 4 that should be corrected as follows: 1. In Figure 4b, the line colors in the label were reversed. We have corrected them so that the red color identifies the curve of the PM6:mBzS-4F-based device and the green color identifies that of the PM6:EHBzS-4F-based device. 2. In Figure 4b, the EQE curve of the PM6:EHBzS-4Fbased device (the green curve) was misplaced. While overlaying the two EQE curves together to create Figure 4b, we did not notice that the two layers have different yaxis scales. We have corrected this by unifying the y-axis of the two curves. The original EQE data of PM6:EHBzS-4F are presented as Supporting Information for credibility. 3. In Figure 4c, the colors of the points in the plot and the label were reversed from those used in the other panels. We have changed them so that the red color identifies the data for the PM6:mBzS-4F-based device and the green color identifies that of the PM6:EHBzS-4F-based device, and the colors are used consistently in the whole figure. We have also checked the manuscript carefully and noted the following corrections: 4. On page 12, in the paragraph corresponding to EQE spectra, the third sentence should be revised as follows, in agreement with the updated EQE curves: “However, the PM6:EHBzS-4F-based device showed only comparable photoresponse between 500 to 670 nm.” 5. On page 12, in the paragraph following the one mentioned above, regarding the fitting curves of light intensity-dependent current-voltage profiles (Figure 4d), the description should be revised as follows: “the calculated slopes are 1.12 and 1.13 kT/q for devices based on PM6:mBzS-4F and PM6:EHBzS-4F, respectively.”
