A crosslinked organic hole‐transporting layer (HTL) is developed to realize highly efficient and stable perovskite solar cells via a facile thiol‐ene thermal reaction. This crosslinked HTL not only facilitates hole extraction from perovskites, but also functions as an effective protective barrier. A high‐performance (power conversion efficiency: 18.3%) device is demonstrated to show respectable photo and thermal stability without encapsulation.
