Eventually Dye Sensitized Solar Cell Moving Towards Nature
The future of sustainable energy depends upon the use of natural materials which support eco-system. Dye
sensitized solar cell closely reflect the nature pattern by using natural materials. In this study, we explored different regional
natural plants as a photosensitizer for dye-sensitized solar cell under the sunlight. Four natural plants selected
Alkannatinctoria root, Liquorice root, Romaine lettuce and Opuntia were selected for dye-sensitized solar cell and compared
different factors under the sunlight at 12:30 pm by sunny day. All plants extracted dyes performance were analyzed by open
circuit voltage (Voc) and short circuit current (Isc). The obtained results were compared with the synthetic dye N719 as a
reference dye. At the time of testing temperature were 35oC, when relative humidity recorded 30%.The open circuit voltage
ranging from 0.533mv to 0.382mv and short circuit photocurrent up to 0.13mA/cm2 noted. The various features of dyes
examined such as light absorbance and functional groups by using UV-VIS and FTIR.
