The potential of porphyrin derivatives as hole\u2010transporting materials (HTMs) for perovskite solar cells (PSCs) has recently been demonstrated, but knowledge of the relationships between the porphyrin structure and device performance remains insufficient. In this work, a series of novel zinc porphyrin (PZn) derivatives has been developed and employed as HTMs for low\u2010temperature processed PSCs. Key to the design strategy is the incorporation of an electron\u2010deficient pyridine moiety to down\u2010shift the HOMO levels of porphyrin HTMs. The porphyrin HTMs incorporating diphenyl\u20102\u2010pyridylamine (DPPA) have HOMO levels that are in good agreement with the perovskite active layers, thus facilitating hole transfers from the perovskite to the HTMs. The DPPA\u2010containing zinc porphyrin\u2010based PSCs gave the best performance, with efficiency levels comparable to those of PSCs using spiro\u2010OMeTAD, a current state\u2010of\u2010the\u2010art HTM. In particular, PZn\u2013DPPA\u2010based PSCs show superior air stability, in both doped and undoped forms, to spiro\u2010OMeTAD based devices.<\/jats:p>","DOI":"10.1002\/cssc.201701526","type":"journal-article","created":{"date-parts":[[2017,9,5]],"date-time":"2017-09-05T22:29:03Z","timestamp":1504650543000},"page":"3780-3787","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["Diphenyl\u20102\u2010pyridylamine\u2010Substituted
