Retraction: Neodymium and Praseodymium Doped Perovskite Materials for Highly Stable CuInS2‐Hole‐Transport Layer‐Based Perovskite Solar Cells

“Neodymium and Praseodymium Doped Perovskite Materials for Highly Stable CuInS 2 ‐Hole‐Transport Layer‐Based Perovskite Solar Cells” by R. Taheri‐Ledari, S. Gharibi, A. Maleki, S. Akin, and A.E. Shalan Energy Technol., 2022, 2100936. The above article, published online on 15 December 2021 in Wiley Online Library, has been retracted by agreement between the former journal Editor in Chief John Uhlrich, the interim Editor in Chief Till von Graberg, and Wiley‐VCH GmbH. Data irregularities in Figures 2b and 5b were pointed out by authors S. Akin, A. E. Shalan and corroborated by peer review from a specialist in the experimental technique. The authors were unable to provide the complete original data to restore confidence in these results. The retraction was necessary as the validity of the conclusions is substantially affected by these irregularities. While S.A. and A.E.S. agreed with the decision to retract the manuscript, R.T.L., A.M., and S.G. did not. Author contributions: R.T.L: Wrote the manuscript and interpreted the analyses. He has also drawn the graphics used in the manuscript. S.G: Performed all practical stages and provided the analyses. A.M: Managed all stages of the work, and financially supported the expenditures (Supervisor). S.A: Revised the manuscript and addressed the reviewers' comments. A.E.S: Edited the manuscript and improved the English presentation.
