Evolution of solar cell based on natural molecules flourished expeditiously, which is a good alternative for silicon-based solar cells or thin film technologies due to their low assembling cost, lightweight and flexibility. But natural dye-based dye-sensitized solar cell (DSSC) has low cell efficiency and stability, which limits the use of organic solar cells. In this research, natural green dye extracted from spinach (Spinacia oleracea) and used as a sensitizer source for natural dye-based DSSC. The measured cell efficiency of natural green dye-sensitized DSSC was 0.398%. Also, the cell stability test has been carried out by measuring the degradation rate (cell efficiency) by aging the dye molecule for DSSC has been conducted after 48, 96, 144 and 196 h under 100mW/cm2 illumination (1.5 AM) at the ambient condition.
