The work by Congcong Wu et al., presented in article number 1800052 , provides a breakthrough to improve the long‐term stability of perovskite solar cells (PSCs) by a homogeneous hybrid microstructure where encapsulation occurs at the molecular level. In this process the hydrophobic polymer, poly(methyl methacrylate) (PMMA), is introduced into the 2D layered MAPbI 3 perovskite intermediates, resulting in chemical coordination and self‐assembly into 3D perovskite grains with PMMA coated along the grain boundaries, which offers full protection against the environmental factors while providing high photovoltaic performance.
