Self-assembled monolayer hole-transporting materials stabilize perovskite solar cells

Abstract

The development of active life for PSCs remains stagnant ascribing to the unstable structure of self-assembled monolayer hole-transporting materials (SAMHTMs) with heteroatom substitution. Xue and co-workers introduced a chemical inert and extensive delocalized structure into the rigid self-assembled molecule Py3, which greatly increased the PCE and long-term stability of PSCs.
