Erratum: Surface ligands for methylammonium lead iodide films: Surface coverage, energetics, and photovoltaic performance (ACS Energy Letters (2020) 5: 3 (799−806) DOI: 10.1021/acsenergylett.0c00054)

The Supporting Information file was updated to correct for erroneously transcribed equations and values along with incorrectly calculated molar masses and atomic numbers. The equations used for the calculations performed in the original Letter were correct, and the correct kinetic energies were used in the original calculations. However, the corrections to the molar masses and atomic numbers, as indicated in this Correction, do result in minor changes of 1-3% in the surface coverage values reported in the Letter. Here, the surface coverage of OPA changes from 96% to 97%, BrBA changes from 69% to 66%, and OCA changes from 71% to 69%. Considering the uncertainties in surface coverages reported in the Letter of ±4% and ±10%, the previous and corrected values fall well within the uncertainty ranges. The following changes were made to the Supporting Information: • In equation S4, “0.316 × 108” was updated to "0.316 x 1010.5". • In the line below equation S4, “A is the atomic molar mass” was updated to “A is the molar mass". • In Table S2, the kinetic energy for MAPbI3 and OPA was changed from 886.76 to 866.76; the atomic number was changed from 45 to 42 for PA, from 109 to 106 for OPA, and from 85 to 82 for PPA; the attenuation length was changed from 2.741 to 2.816 for PA, from 3.46074 to 3.496 for OPA, and from 3.303066 to 3.071 for PPA. • In Table S3, the kinetic energy for MAPbI3, OCA, and BrBA was changed from 886.76 to 866.76; the molar mass was changed from 45.03 to 46.03 for CA and from 156.002 to 157.003 for 4-bromophenyl; the atomic number was changed from 25 to 24 for CA, from 82 to 80 for OCA, from 100 to 98 for BrBA, and from 77 to 76 for 4-bromophenyl; and the attenuation length was changed from 2.984 to 3.119 for CA, from 3.658 to 3.692 for OCA, from 2.921 to 2.942 for BrBA, and from 3.362 to 3.368 from 4-bromophenyl. • In Equation S5, “Heptyl” was changed to “Octyl”. • In Equation S6, "Octyl" was changed to “Heptyl”.
