A series of new D2h symmetric porphyrins (MDA4, MTA4, and MDA8) with donor‐π‐donor structures have been synthesized as the hole‐transporting materials for perovskite solar cells (PSCs). The novel porphyrin molecules feature a D2h symmetrically substituted ZnII porphyrin core and two kinds of donor systems (diarylamine (DAA) and triarylamine (TAA)), which can regulate energy level, increase thermal...
