Dye sensitized solar cell (DSSC) is the only solar cell that can offer both the flexibility and transparency. Its efficiency is comparable to amorphous silicon solar cells but with a much lower cost. Fresh green Leaves of Botuje ( Jathopha curcas Linn) was extracted and used as a sensitizers for the development fabrication of dye sensitized solar cells . The Solar cells sensitized by Botuje ( Jathopha curcas Linn) extracts achieved up to Jsc 0.69mAcm2, Voc 0.054 V, Pmax 0.033mWcm2 and ff 0.87. The energy conversion efficiency (η) of the cells is 0.12%. The Phytochemical screening of the extract indicates the absence of anthraquinones and presence of flavonoids. The results obtained with extracts of Botuje (Jathopha curcas Linn shows a conversion of visible light into electricity by using low costs developed natural dyes as wide band-gap semiconductor sensitizers in dyesensitized solar cells.
