Extract of NEEM bark consisting of Azadirachtin a chemical compound belonging to the limonoids family is used as sensitizer of nc-TiO2. In order to cover wider spectral absorption, cocktail of Neem and methylene blue is used. The charge transport mechanism was studied to understand the contribution of interface resistance to the performance of cell by recording frequency vs. phase angle (Bode plot) with the help of EIS (electrochemical impedance spectroscopy).
