| Summary: | Bacterial dyes have attracted significant attention as sustainable alternatives to conventional synthetic
dyes in dye-sensitized solar cells (DSSCs). Present research has concentrated on a narrow selection of
bacterial species, leaving the potential of numerous other pigments largely unexplored. This study aims
to characterise pigments extracted from Chromobacterium violaceum and Ralstonia sp and to
determine their potential as photosensitizers in DSSCs. The pigments were analysed in terms of their
spectroscopic and structural properties, determined by Ultraviolet visible UV-Vis and Fourier-
Transform Infrared spectroscopy. The DSSCs efficiency of the pigments were also investigated. Our
results showed that the pigments produced by the aforementioned bacteria were identified as violacein
and carotenoid. Preliminary investigation into the feasibility of the pigments showed the promising
utility of both pigments as photosensitizers for DSSCs. This study provides useful insights into the
potential of novel bacterial pigments as photosensitizers for the development of cost-effective and
ecologically friendly DSSCs. |
