tcsc0354 D149 Dye

D149 Dye is an indoline-based dye, which is a high-extinction-coefficient metal-free organic sensitizer.

In Vitro: D149 is a metal-free organic dye, which is promising all-organic alternatives. D149 displays power conversion efficiency of up to 9%. Furthermore, D149 has a peak extinction co-efficient of 68700 M^-1 cm^-1 at 540 nm, significantly higher than 13900 M^-1cm^-1 at 535 nm for N719^[1]. D149, a metal-free indoline dye, is one of the most promising sensitizers for dye-sensitized solar cells (DSSCs) and has shown very high solar energy conversion efficiencies of 9%. D149 shows a large number of unresolved aromatic and olefinic signals between 7 and 7.5 ppm^[2]
