In article number 1903173, Jin‐Kyu Kang, Dae‐Hwan Kim and co‐workers report a liquid‐assisted grain growth mechanism for a vacuum processed Cu 2 ZnSn(S 1− x Se x ) 4 (CZTSSe) absorber. The liquid phase is mainly composed of Cu, Sn, and Se. Through this liquid assisted grain growth, it is possible to form CZTSSe thin films with large‐sized grains at low temperatures.
