Abstract

Abstract A series of new push–pull phenothiazine-based dyes (HL1, HL2, HL3, HL4) featuring various π spacers (thiophene, 3-hexylthiophene, 4-hexyl-2, 2′-bithiophene) and double acceptors/anchors have been synthesized, characterized, and used as sensitizers for dye-sensitized solar cells (DSSCs). Among them, the best conversion efficiency (7.31%) reaches approximately 99% of the N719-based (7.38%) DSSCs fabricated and measured ...
