Photophysicochemical properties of porphyrinoid systems, their characterization (fluorescence and TCSPC, flash-photolysis, UV-Vis., NMR, and FT-IR) and applications (photocatalysis, photodynamic therapy, nonlinear optics and dye-sensitized solar cells (DSSCs)), computational chemistry, nanomaterial science (TEM, SEM, X-ray diffraction and Raman spectroscopy)



Currently, our research focuses on the design and development of efficient dye molecules as sensitizers in DSSCs. Theoretical and experimental methods, such as DFT/TD-DFT and determination of the electrical responses of the fabricated prototype cells from the synthesized dye molecules are employed respectively, to achieve our overall goal.
