ABSTRACT:
D149, a metal-free indoline dye, is one of the most promising sensitizers for dye-sensitized solar cells (DSSCs). The D149 sensitizer with the solvent acetonitrile gives two distinct absorption bands: first band is in the region of 350-430 nm due to (π–π*) electron transitions of the conjugated molecules, and the next in the region of 430-614 nm can be allocated to an intermolecular charge transfer (ICT) between the electron-donor and electron-acceptor anchoring moieties.Upon optimization, the device given a Jsc of 13.2mA/cm2, Voc of 752mV, and FF of 0.749 % and the conversion efficiency of 7.4%.
