Application of indoline dyes attached with strongly electron-withdrawing carboxylated indan-1,3-dione analogues linked with a hexylthiophene ring to dye-sensitized solar cells

摘要

An indoline dye attached with a carboxylated indan-1,3-dione moiety linked with a hexylthiophene ring exhibited the highest conversion efficiency among six analogues and D205. This result comes from the bathochromic UV-vis absorption band, suitable energy levels, good stability for redox process, and sufficiently long excited-state lifetime. (C) 2018 Elsevier Ltd.
