New bipyridine ruthenium dye complexes with amide based ancillary ligands as sensitizers in semitransparent quasi-solid-state dye sensitized solar cells

[Display omitted] •Three new synthesized ruthenium complexes containing 2,2′-bipyridine-4,4′-dicarboxamide.•Optical differences were associated to different electron donor strength of ancillary ligands.•5.0% overall performance for propyl substituent complex in semitransparent solar cells. A series...
