Buffer Layers: Copper Oxide Buffer Layers by Pulsed‐Chemical Vapor Deposition for Semitransparent Perovskite Solar Cells (Adv. Mater. Interfaces 1/2021)

In article number 2001482, Helen Hejin Park, Jangwon Seo, and co‐workers introduce copper oxide by pulsed‐chemical vapor deposition as a buffer layer, which protects the organic hole transport layer from sputtering damage during sputtering of the transparent conducting oxide. On the cover the authors illustrate the precursors used during their copper oxide buffer layer approach integrated in semitransparent perovskite solar cell applications.
