Abstract: Plants’ leaves can prevent the UV attack although the ozone layer is still damaged by CFC emission due to the activities of human beings, and natural dyes extracted from leaves can be used in dye-sensitized solar cell (DSSC). In this work, the absorbance spectra and light harvesting efficiency (LHE%) of natural dye solutions extracted from the leaves of henna (Lawsonia inermis), ironwood (Xyila xylocarpa), sour sop (Annona muricata), mango (Mongifera indica), and marian (Bouea macrophylla) have been studied by UV-VIS spectroscopy to protect the effects of UV attack and to use as sensitizer for DSSC.
