Tshwane University of Technology, Department of Chemistryhttp://hdl.handle.net/10204/7422A thesis submitted to the Faculty of Engineering, Tshwane University of Technology, in fulfillment of the requirements for the degree Master of TechnologyThis study reports the successful synthesis and integration of metallo-octacarboxyphthalocyanines-multi-walled carbon nanotubes (MOCPc-MWCNTs) (M = Zn, Ga(OH) and Si(OH)2) hybrid system for the application of dye solar cells. The metal octacarboxyphthalocyanines-multi-walled carbon nanotubes hybrid was prepared through non- covalent (Pi)p-(Pi)p stacking. The metallo-octacarboxyphthalocyanines-multi-walled carbon nanotubes hybrid was later employed in dye solar cells as a photosensitiser of choice to enhance the performance and efficiency of this device. The dye solar cell devices were fabricated using metallo-octacarboxyphthalocyanines-multi-walled carbon nanotubes hybrid adsorbed on the TiO2 semiconductor and further characterised with solar simulator. The physical and electrochemical characterisations of metallo-octacarboxyphthalocyanines-multi-walled carbon nanotubes hybrid were investigated using spectroscopy (UV-Vis, FTIR, EDX, XRD), microscopy (TEM, SEM and AFM), TGA, and electrochemistry (Cyclic voltammetry, photo-chronoamperometry and electrochemical impedance spectroscopy). The effect of multi-walled carbon nanotubes on metallo-octacarboxyphthalocyanine was firstly verified by UV-Vis spectroscopy. The UV-Vis spectroscopy of metallo-octacarboxyphthalocyanines in DMF showed the characteristic Q-band at around 680 nm. Upon integration with multi-walled carbon nanotubes the Q-band was red-shifted.enPhthalocyaninesCarbon nanotubesDye solar cellsReportMphahlele, N.
