Facile Thiol‐Ene Thermal Crosslinking Reaction Facilitated Hole‐Transporting Layer for Highly Efficient and Stable Perovskite Solar Cells

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.
