General description

D131 dye is an indoline based organic dye that has a large band-gap and can be used as a sensitizer in organic electronics. It shows a power conversion efficiency of 5.6% and can enhance photo-excitation of the electrochemical devices.

Application

D131 can be used in dye sensitized solar cells (DSSCs) as a photosensitizer with high charge mobility and absorption coefficient.
Organic photosensitive yellow dye having excellent photoelectric conversion efficiency as a metal-free dye,
Significant improvement in the conversion efficiency (11.1%) of black-dye-based dye-sensitized solar cells by cosensitization with D131 dye
