Highly crystalline SnO 2 is demonstrated to serve as a stable and robust electron‐transporting layer for high‐performance perovskite solar cells. Benefiting from its high crystallinity, the relatively thick SnO 2 electron‐transporting layer (≈120 nm) provides a respectable electron‐transporting property to yield a promising power conversion efficiency (PCE)(18.8%) Over 90% of the initial PCE can be retained after 30 d storage in ambient with ≈70% relative humidity.
