Abstract |
|
|
| Herein, we have studied dye sensitized solar cell (DSSC) from natural dyes extracted from fruit and leaf of Discopodium peninervum as photosensitizers based on TiO2 photoanode material. The optical characterization were carried out using UV-Vis spectroscopy the as optical properties were studied. The photovoltaic performances of the as fabricated DSSC from fruit and leaf of Discopodium peninervum in terms of maximum current density (Jmax), maximum voltage (Vmax) ̧ maximum power (Pmax), open circuit voltage (VOC), short circuit current density (Jsc), fill factor (FF), and power conversion efficiency (η) were studied under sunlight approximately 100 mW cm-2 illumination. The recorded power conversion of the solar cells made from fruit of Discopodium peninervum were 1.201, 0.259, 0.311, 0.313, 1.56, 63.69, and 0.311 respectively and for leaf of Discopodium peninervum were 2.68, 0.550, 1.474, 0.650, 3.60, 62.99, and 1.474 respectively. Also the stability of the as prepared DSSC after their assembly for both fruit and leaf were studied, and as the duration of cell assembly increase the efficiency of the as prepared DSSC rapidly decreased. It shows the formation of fast degradation, and this may due to the nature of high volatility of liquid electrolyte used which may quench the dye solutions. |
