This research uses betalain extract and Spinacia oleracea Dye as a sensitizer source for dye-sensitized solar cell
(DSSC) dependent on TiO2, which has entirely different range of absorption. The dye combination displayed a larger absorption
range and increasing absorption of light than a single individual dye. As a consequence, Dye sensitized solar cell by the dyes
mixture has demonstrated improved efficiency of the cells. Dye sensitized solar cell sensitized by betalain and spinacia oleracea
dye yields cell output of 2.45 per cent and 5.03 per cent respectively, according to experimental findings. Dye sensitized solar
cell were co-sensitized to find the optimal mixture by combining the dyes at 3 specific volume ratios (1:1 , 1:2 and 2:1). The
formulated mixture of betalain and spinacia oleracea dye (at 1:2 ratio) produces 8.02 per cent overall performance.
