Comment on "Spectroscopic ellipsometry and solar cell performance of Cs-doped MA<sub>0.05</sub>FA<sub>0.95</sub>Pb(I<sub>0.98</sub>Br<sub>0.02</sub>)<sub>3</sub> triple cation perovskite thin films for solar cell applications" by A. M. El-naggar et al. (Applied Physics A (2022) 128:378)

- Abstract
The original manuscript of the published paper (Applied Physics A 128:378, 2022) was not revised properly pre-submission, and it has some scientific errors in its current published form. These errors create intrinsic contradictions and inconsistencies in the published paper, and thus they must be outlined and corrected. Furthermore, the reported photovoltaic performance parameters in the paper require some corrections. Using the FF% values reported in Table 1 and the correct JSC and VOC values from the J-V curves' intercepts, then the lowest power conversion efficiency (PCE%) value is 10.73% for the 5% Cs-doped film, not the 7% Cs-doped one.
