Here, we show a judiciously tailored organic photosensitizer, coded MS5, featuring the bulky donor N -(2\u2019,4\u2019-bis(dodecyloxy)-[1,1\u2019-biphenyl]-4-yl)-2\u2019,4\u2019-bis(dodecyloxy)- N -phenyl-[1,1\u2019-biphenyl]-4-amine and the electron acceptor 4-(benzo[ c ][1,2,5]thiadiazol-4-yl)benzoic acid. Employing MS5 with a copper (II\/I) electrolyte enables a dye-sensitized solar cell (DSC) to achieve a strikingly high V oc of 1.24 V, with the V oc deficit as low as 130 mV and an ideality factor of merely 1.08. The co-sensitization of MS5 with the wider spectral-response dye XY1b produces a highly efficient and stable DSC with the PCE of 13.5% under standard AM1.5 G, 100 mW cm \u22122 solar radiation. Remarkably, the co-sensitized solar cell (active area of 2.8 cm 2 ) presents a record PCE of 34.5% under ambient light, rendering it very attractive as an ambient light harvesting energy source for low power electronics.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.1038\/s41467-021-21945-3<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Dan Zhang, Marko Stojanovi\u0107, Yameng Ren, Yiming Cao, Felix T.
