Photovoltaic Devices: Gravure‐Printed Flexible Perovskite Solar Cells: Toward Roll‐to‐Roll Manufacturing (Adv. Sci. 7/2019)

Abstract

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.
