1 To improve and enhance the electronic and optical properties of target organic dye molecules using the combined theoretical and experimental studies.
2 To provide useful information such as calculated energy band gap, electronic transition and optical properties of organic dye-sensitizer to experimentalist for the molecular level of understanding.
3 To study mode of adsorption of dye molecule on TiO2 surface which related to effect of electron injection from dye to external load and then related to power conversion efficiency of DSC.
4 To develop and design new efficient dye solar cells (DSC) based on D-?-A using the electronic and optical properties from our known target molecules.
