Effect of donor (tetradecyloxy) and acceptor (carboxamide) groups in trans-stilbene for DSSCs: Quantum chemical investigations

- Stilbene based dye sensitizer has been designed first time for DSSC applications.
- 4′-Tetradecyloxy-stilbene-4-carboxamide sensitizer exhibits large dipole moment.
- The large dipole moment would be expected to give high photo-current conversion efficiency in practical DSSCs.
- It is a promising candidate for practical DSSCs applications.
