In article number 1802094 , Jangwon Seo and co‐workers report gravure printing of methylammonium lead iodide for the fabrication of flexible perovskite solar cells. Via the optimization of precursor solutions and processing parameters, the resulting all‐printed device shows 17.2% power conversion efficiency (PCE). The roll‐to‐roll (R2R) process of the gravure printing is also demonstrated, and the partial R2R processed device shows 9.7' PCE.
