Description:

Dyenamo Orange (D35) has been established worldwide as a reference organic dye for DSSCs. Excellent device stability has been obtained both under light and after at least 1000 h storage in darkness at temperatures of 85°C.

D45

Description:

D45 is a variant of Dyenamo Orange (D35) designed for use with aqueous electrolytes. The shorter alkyl chains on the donor side decreases the hydrophobicity of the sensitized surface, which improves wetting of the electrode when used with polar electrolyte solvents. Additionally, the smaller size of D45 compared to D35 enables it to reach higher dye loadings which allows the use of thinner TiO₂ films.
