Author Correction: Photoswitchable isomers to improve grain boundary resilience and perovskite solar cells stability under light cycling

In the version of this article initially published, in Fig. 1b (upper panel), the x-axis label was "Time (h)" but should have been "Time (min)". In the captions for Fig. 1 and Fig. 4, the sentence "The coloured areas represent error bars" has been deleted, as error bars are already defined as mean ± SD. For consistency in terminology, "SnO 2 " was replaced with "SnOₓ" in the caption for Fig. 3b and Supplementary Fig. 34; this adjustment does not affect experimental procedures or data. In the second paragraph of the "Operational stability of the devices" section, "40 days" should have read "500 h". In Supplementary Note 1, "1,500 cycles" was corrected to "1,200 cycles." Additionally, in the caption for Supplementary Fig. 13, the compound Dca-Abz (azobenzene-4,4′-dicarboxylic acid) was mistakenly referred to as 4-(phenylazo)benzoic acid. This was a chemical name labeling error only; the molecular structure, experimental materials, and all associated data remain correct, and the caption has been amended accordingly. These corrections do not alter the results or conclusions of the article.
