Abstract
Nanorods (NRs) of TiO2 have biogenically been prepared, i.e., from the extract of Phellinus linteus mushroom. The presence of mixed anatase and rutile TiO2 phases, rod-type crystallites, and 114.16 g/cm2 and 3.7-nm surface area and pore-diameter is evidenced by various measurements. The dye-sensitized solar cell (DSSC) is fabricated using as-prepared TiO2 NR-based photoanode in the presence of N719 sensitizing dye prepared in 0.5 M lithium iodide and 0.05 M iodine with acetonitrile as redox electrolyte. Solar-to-electrical energy conversion efficiency (η%) of 3.8 % is recorded and electrochemical impedance spectroscopy (EIS) curve obtained for TiO2-based DSSCs is fitted using an equivalent circuit for explaining various electrical parameters involved in developed DSSC.
