In article number 2009246, Jung Hwa Seo, Bright Walker, and co‐workers demonstrate that a simple Cu(II) polyelectrolyte is able to create effective p‐type junctions in perovskite solar cells by creating an interfacial dipole which effectively alters the energy band structure to extract positively charged holes. This innovation is used to greatly improve the performance of methylammonium lead iodide perovskite solar cells.
