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%.
