Abstract：

Inverted　p-i-n　structure　perovskite　solar　cells　(PSCs)　have　attracted　considerable　attention　in　consideration　of　high-efficiency,　long-term　stability,　and　cost　reduction,　which　represent　the　key　challenges　in　advancing　the　commercialization　of　PSCs.　In　order　to　address　the　issue　of　defect-related　nonradiative　recombination,　we　enhanced　the　interfacial　passivation　between　the　perovskite　layer　and　electron　transfer　layer　with　crown　ether　derivatives　in　p-i-n　PSCs.　By　a　combination　of　first-principles　calculations,　photoluminescence　(PL)　and　time-resolved　photoluminescence　(TRPL)　spectra,　and　grazing-incidence　wide-angle　X-ray　scattering　(GIWAXS)　characterization,　we　provided　an　understanding　of　the　passivation　mechanism　and　obtained　an　efficiency　of　23.3%　in　NiOx-based　p-i-n　PSCs,　which　lowered　the　nonradiative　recombination　with　25%　of　the　voltage　losses.　Furthermore,　the　unencapsulated　PSCs　kept　92%　of　the　initial　efficiency　following　1224　h　of　aging,　which　demonstrated　remarkable　long-term　stability.　The　inverted　structure　with　interfacial　passivation　could　provide　great　potential　for　high-efficiency　and　stable　PSC　designs　and　promote　the　commercialization　of　PSCs.　©　2024　American　Chemical　Society.
