AbstractThis cover (DOI: 10.1002/inf2.12396) displays a quasi‐2D perovskite solar cellwithreverse‐gradedquantum well distribution, which promotes the charge carrier transport. The small‐n phase at the top part of the quasi‐2Dperovskite film protects the surface from the damage of water and oxygen. Intermediate phase assisted sequential deposition is demonstrated firstly to fabricate MA‐free quasi‐2D ACI perovskiteswith reverse‐graded QW distribution and improved vertical orientation.
