In article number 1901019 Zong‐Xiang Xu, Michele Muccini and co‐workers report highly‐efficient, low‐cost, solution‐processed perovskite solar cells, exhibiting remarkable environmental stability. The fabrication strategy relies on the rational design of the molecular structure of arylamine‐substituted copper(II) phthalocyanine (CuPc) derivatives, which are used as dopant‐free hole‐transport materials. The resulting devices reach a power conversion efficiency of 19.7% and display enhanced long‐term stability with respect to standard (doped) materials.
