Corrigendum to “High-performance perovskite solar cells using graphene quantum dot modified SnO₂/ZnO photoelectrode” [Mater Today Energy 22 (2021) 100853] (Materials Today Energy (2021) 22, (S2468606921002185), (10.1016/j.mtener.2021.100853))

The authors regret that an error was made in Figure 3e and need to be corrected: It has been determined that an error occurred during the plotting of the data. Specifically, the plots corresponding to the conditions “0% GQDs” and “4% GQDs” were mistakenly double-pasted due to the inadvertent use of the offset option. It was found that the data imported to the plotting software and the closeness of the data made it challenging to recognize the error immediately. The updated Figure 3e is presented here which accurately differentiates the data for “0% GQDs” and “4% GQDs-doped SnO₂/ZnO ETLs”.[Formula presented] Updated Figure 3e. Absorption spectra of Perovskite film corresponding to pristine SnO₂, 0% GQD-doped SnO₂/ZnO, and 4% GQD-doped SnO₂/ZnO ETLs. The updated Figure does not impact the conclusions of the article. The correction solely addresses the accurate representation of the data presented in Figure 3e and does not change the overall results or discussions of the study. The authors would like to apologize for any inconvenience caused.
