Emerging all‐inorganic CsPbI3 perovskite quantum dots offer colloidal synthesis and processing using industrially friendly solvents. This is desirable for solar‐cell applications and will catalyze new structures for optoelectronic devices. In article number 2000449, Jianyu Yuan, Wanli Ma, and co‐workers report the development of a new surface ligand management strategy, which improves on the state‐of‐the‐art efficiency of CsPbI3 quantum‐dot solar cells.
