摘要

Coumarin is a versatile heterocyclic compound with wide applications in the fields of medicines, sensors, fluorescence probes, optoelectronics, and photovoltaics. Coumarin shows fluorescence in the visible region and suitable substitutions with various chromophores make it tunable for applications in the latest (third) generation of solar cells. Dye-sensitized solar cells have profited well with attractive coumarin-based photosensitizers via the various structural frameworks of coumarin, namely D-A, D-π-A, D-D-π-A, and D-A-π-A. The functionalization of coumarin dyes as donors with appropriate fullerene or fullerene-free acceptors is significantly utilized for both binary and ternary blends in bulk heterojunction organic solar cells. This review article pays particular focus to the design, synthesis, and photovoltaic analysis of various coumarin dyes for fabrication in both DSSCs (dye-sensitized solar cells) and OSCs (organic solar cells), reported since 2014.
