Abstract :
The new technological way of Dye-Sensitized Solar Cell (DSSC) similar to photosynthesis process has attracted much attention since its demonstrate a great potential due to the use of low-cost materials, ease of fabrication process and environmentally friendly sources of technology. This paper discovers the use of natural dyes from Blue Pea flower which act as a sensitizer in DSSC and in addition has a potential in absorbing visible light spectrum. The absorption spectra of the dyes have been investigated by UV-Vis Spectrophotometer. Fourier transform infrared (FTIR) is used to characterize the functional active group of dyes. Photovoltaic parameters reveal that the blue pea flower extract resulted in 0.19% energy conversion efficiency (η), short circuit current (Isc) of 0.63 mA/cm^2, open circuit voltage (Voc) of 0.60 V, and fill factor (FF) of 0.50.
