This process employs highly acidic bath of perchloric acid (pH &lt; 2) and a large current density on the surface of Titanium foil to form nanostructures. The diameter and length of rutile TiO2 nanoneedle is similar to 8 nm and 100 nm respectively (aspect ratio &gt; 10). Dye sensitized solar cell (DSSC) configured using such rutile TiO2 flowers is shown to exhibit IPCE of 30% and power conversion efficiency of similar to 3.6%.</p>10aAnodization10aDSSC10aNanoneedles10aRutile TiO21 aHyam, Rajeshkumar, S.1 aBhosale, Reshma, K.1 aLee, Wonjoo1 aHan, Sung-Hwan1 aHannoyer, Beatrice1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/room-temperature-synthesis-rutile-tio2-hierarchical-nanoneedle-flower-morphology-dye-0
