%X To
develop new hole-transporting materials (HTMs) for efficient and stable
perovskite solar cells (PSCs), 5,10,15,20-tetrakis{4-[N,N-di(4-methoxylphenyl)amino-phenyl]}-porphyrin
was prepared in gram scale through the direct condensation of pyrrole
and 4-[bis(4-methoxyphenyl)amino]benzaldehyde. Its Zn(II) and Cu(II)
complexes exhibit excellent thermal and electrochemical stability,
specifically a high hole mobility and very favorable energetics for
hole extraction that render them a new class of HTMs in organometallic
halide PSCs. As expected, ZnP as HTM in PSCs affords
a competitive power conversion efficiency (PCE) of 17.78%, which is
comparable to that of the most powerful HTM of Spiro-MeOTAD (18.59%)
under the same working conditions. Meanwhile, the metal centers affect
somewhat the photovoltaic performances that CuP as HTM
produces a lower PCE of 15.36%. Notably, the PSCs employing ZnP show a much better stability than Spiro-OMeTAD. Moreover,
the two porphyrin-based HTMs can be prepared from relatively cheap
raw materials with a facile synthetic route. The results demonstrate
that ZnP and CuP can be a new class of HTMs
for efficient and stable PSCs. To the best of our knowledge, this
is the best performance that porphyrin-based solar cells could show
with PCE > 17%.
