Correction: Awino, C., et al. Investigation of Structural and Electronic Properties of CH₃NH₃PbI₃ Stabilized by Varying Concentrations of Poly(Methyl Methacrylate) (PMMA). Coatings 2017, 7, 115

In the original version of article [1], the lists of authors and affiliations, and the Acknowledgements and Author Contributions were incomplete. The manuscript was written by the co-authors, however the original version, the concept for the experiments, the initial experiments, extended supervision for continuation of experiments, and detailed and numerous discussions and explanations were provided by Dr. Pongthep Prajongtat, Dr. Thomas Dittrich and Prof. Dr. Bernd Rech. These people thus qualify for authorship and are added to the list of authors. All experiments were performed during a scholarship of the corresponding author at the Helmholtz-Zentrum Berlin.

The correct author list, Acknowledgements and Author Contributions are as follows:
