Phthalocyanine molecules have the potential to be used in select Dye Sensitized Solar Cells (DSSCs) and Luminescent Solar Concentrators (LSCs), due to UV-Vis absorbance in the 300-450 (nm) Soret Band, corresponding to π HOMO-1 to π* LUMO transition and 550-690 (nm) Q-band, corresponding to π HOMO to π* LUMO transitions. In this study Tetranitro Zinc (II) Phthalocyanine is synthesized via base catalysis before the product is characterized via IR, 1H NMR & UV-Vis analysis. Assessing the desirability of the Tetranitro Zinc (II) Phthalocyanine as a solar organic semiconducting dye in DSSCs and LSCs. The desirability is assessed by novel computational DFT calculations, of the aggregation binding mode to deduce if Aggregation-Caused Quenching (ACQ) is occurring in the aggregated sample. ACQ is known to reduce DSSCs and LSCs generation of useful photo-active current. Aggregation-Caused Quenching (ACQ) is mathematically indicated in Phthalocyanine aggregation and Tetranitro Zinc (II) Phthalocyanine’s desirability is assessed for further use in DSSCs and LSCs.
