Abstract

Energy continues to be the currency that drives all technology. Thus, the quest for energy remains vital to energy sustainability. In the wake of several adverse consequences of indiscriminate combustion of fossil fuel, there is an urgency to exploit our natural environment for ecologically benign alternatives. Ringwood also known as S. anisatum or Aniseed is a common sight in many ornamental gardens. It provides the customary thick layer of plush greenery typical of such settings. In addition, its characteristic aromatic leaves are capable of attaining a height of 45 metres. These attributes consolidated in the choice of Ringwood as a suitable candidate with a rich and viable store of solar energy. This gave the impetus to convert this S.anisatum store of photons of sunlight to electricity. Preliminary phytochemical screening results revealed the presence of phenols, flavonoids, tannins, glycosides, terpenoids and protein, a wide chromophore selection for charge transport. The study of S.anisatum absorbance-wavelength properties with UV/VIS spectroscopy shows S.anisatum dye extract having multiple peak absorbances with its optimum in the near ultraviolet region although, it absorbs optimally in the visible region of the electromagnetic spectrum. This is a Porphyrin dye characteristic, a desirable attribute that facilitates wider spectrum of solar energy absorption. The output
