Following publication, the Editorial Office became aware that the original article [1] may constitute an extension of the previously published Spanish conference paper [2].
Adhering to our standard procedure, the Editorial Office conducted an investigation with the support of the Editorial Board and in full collaboration with the authors. The evaluation confirmed the existence of a direct, undisclosed connection between two papers [1,2], which was found to be inconsistent with MDPI’s citation policy, although it did not constitute redundancy. The authors agreed to correct the publication by adding the following information:
Article title note: † The present work is an extension of the “Nueva instalación de longitud de onda selectiva para la caracterización y envejecimiento de materiales sometidos a altos flujos de radiación solar” presented to “XVIII Congreso Ibérico y XIV Congreso Iberoamericano de Energía Solar, Palma, Spain, 20–22 June 2022; pp. 97–104.”.
A phrase to the last paragraph of Section 1. Introduction: “This is an extended version of the conference paper [9].”.
Reference 9 [2] in the reference list: With this correction, the order of some references has been adjusted accordingly. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
