A surface passivation method for solution‐processed ZnO films based on small molecule ethanedithiol (EDT) treatment is reported by Yizheng Jin, Baoquan Sun, Feng Gao, and co‐workers in article number 1401606. The passivation using EDT treatment on ZnO effectively removes the surface defects and modulates the intragap states with the introduced intragap band. The device performances of inverted organic solar cells based on EDT‐treated, solution‐processed, ZnO electron‐transporting interlayers are significantly improved due to reduced interface recombination and enhanced charge extraction properties.
