Correction to: Scalable fabrication of wide-bandgap perovskites using green solvents for tandem solar cells (Nature Energy, (2024), 10.1038/s41560-024-01672-x)

Correction to: Nature Energyhttps://doi.org/10.1038/s41560-024-01672-x, published online 15 November 2024. In the version of the article initially published, we mistakenly listed the environmental score for DMSO as 4 instead of the correct score of 5, based on the evaluation criteria outlined by CHEM21. This error, along with the transposition of the “NMP” and “DMPU” labels on the x axis, has been corrected in Fig. 1a, as seen below in Fig. 1. (Figure presented.) Original and corrected Fig. 1a. To ensure clarity and accuracy, we have revised our understanding of the combination rules for determining risk levels. Previously, our explanation might have been unclear or misleading to readers. To address this, we have included an excerpt from the CHEM21 solvent guide below, which provides a clear list of solvent risk levels and their ranking rules (Tables 1 and 2). (Table presented.) (Table presented.) CHEM21 solvent guide of “classical” solvents¹ Ranking by default¹ These two tables clearly illustrate the risk levels and comprehensive evaluation criteria for the solvents discussed in our article. To enhance reader understanding, we have also integrated this information into the corrected Fig. 1a, providing a visual representation of the risk levels associated with different solvents. Additionally, we have made two necessary revisions to the second paragraph of the article. The sentence “To address this challenge, the evaluation criteria outlined by CHEM21 offer a guide, categorizing solvents into four groups based on their impact on safety, health and environment¹⁰, namely recommended (no chemical incompatibility under process conditions), problematic (suitable for lab or kilo-scale lab use), hazardous (strong constraints on scale-up) and highly hazardous (solvents to be avoided even in the lab)” has been corrected to “To address this challenge, the evaluation criteria outlined by CHEM21 offer a guide, comprehensively categorizing solvents into three groups based on their impact on safety, health, and environment¹⁰, namely recommended (no chemical incompatibility under process conditions), problematic (suitable for lab or kilo-scale lab use) and hazardous (strong constraints on scale-up).” In the same paragraph, the sentence “The height of the column below the horizontal blue dashed line represents the recommended solvents. The height between the horizontal red dashed line and the horizontal blue dashed line indicates solvents that are problematic. The height of the column above the horizontal red dashed line signifies solvents that are hazardous” has been corrected to “The scoring system assesses risk levels following these rules: the solvent is listed as “hazardous” if it has any one score of ≥8 or two scores of 7; it is “problematic” if it has exactly one score of 7 or two scores between 4 and 7 (that is 4, 5, or 6) with the third score <7; all other scenarios, where one score is ≤6 and the other two are ≤3, are considered as “recommended”.” In the following two sentences, “N-methyl-2-pyrrolidone” and “dimethylpropyleneurea” were transposed; the former is hazardous to health and the latter is considered problematic. In the eighth paragraph under “Photovoltaic performance,” in the sentence “As DMSO can oxidize Sn²⁺, the extent of Sn²⁺ is greater…”, the second instance of Sn²⁺ should have been Sn⁴⁺. These corrections have been made to the HTML and PDF versions of the article.
