An innovative NH 4 I‐induced phase transformation to simultaneously optimize both nucleation and crystal growth processes of perovskite structures is described by Zhuo Kang, Yue Zhang and co‐workers in article number 1701804 . The resulting optimized perovskite quality allows for a 10% increase in photovoltaic performance. Such methodology of introducing novel phase transformations is of universal significance for perovskite solar cell development.
