Here we report a record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global using a hole-transport material composed of a blend of [Cu (4,4\u2032,6,6\u2032-tetramethyl-2,2\u2032-bipyridine) 2 ](bis(trifluoromethylsulfonyl)imide) 2 and [Cu (4,4\u2032,6,6\u2032-tetramethyl-2,2\u2032-bipyridine) 2 ](bis(trifluoromethylsulfonyl)imide). The amorphous Cu(II\/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 \u03bcm-thick mesoscopic TiO 2 scaffold are crucial for achieving such high efficiency. Using time-resolved laser photolysis, we determine the time constants for electron injection from the photoexcited sensitizers Y123 into the TiO 2 and regeneration of the Y123 by Cu(I) to be 25 ps and 3.2 \u03bcs, respectively. Our work will foster the development of low-cost solid-state photovoltaic based on transition metal complexes as hole conductors.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.1038\/ncomms15390<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Yiming Cao, Yasemin Sayg\u0131l\u0131, Amita Ummadisingu, Jo\u00ebl Teuscher, Jingshan Luo, Norman Pellet, Fabrizio Giordano, Shaik M.
