A “Cyanine−Cyanine” Salt Exhibiting Photovoltaic Properties
Résumé
Association between cationic and anionic heptamethine dyes led to the formation of a new organic salt (3) displaying exceptional light harvesting properties in the NIR spectral range and having amphoteric redox character. Preliminary results of molecular bulk heterojunction solar cells based on the title compound 3 and [60]PCBM as the only active layer reveal this new dye as a promising light harvesting material for photovoltaics.
