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-001693nas a2200193   4500008004100000022001400041245015300055210006900208260011000277300001600387490000600403520084100409100002401250700002401274700002001298700002401318700002501342856013201367       2014                        eng d  a2046-206900aNanophase CulnS(2) nanosheets/CuS composite grown by the SILAR method leads to high performance as a counter electrode in dye sensitized solar cells0 aNanophase CulnS2 nanosheetsCuS composite grown by the SILAR meth  aTHOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLANDbROYAL SOC CHEMISTRYcMAY  a21989-219960 v43 a<p>Single phase CulnS(2) (CIS) nanosheets are synthesized on TiO2 coated FTO by the simple technique of Successive Ionic Layer Adsorption Reaction (SILAR) followed by annealing at 500 degrees C. Annealing at a lower temperature of 250 degrees C is found to yield CuS nanoparticles in addition to the CIS phase. Both single phase CIS and the CuS/CIS nanocomposite were examined as counter electrodes for a dye-sensitized solar cell (DSSC). The CIS-CuS composite is found to have a synergistic effect on the catalytic performance toward the reduction of tri-iodide, yielding a power conversion efficiency of 6.3% as compared to pristine CIS (5%) or CuS (3.5%). The possible reasons behind the high performance of the composite are elucidated using cyclic voltammetry (CV) measurements and electrochemical impedance spectroscopy (EIS).</p>1 aBhosale, Reshma, K.1 aAgarkar, Shruti, A.1 aAgrawal, Ishita1 aNaphade, Rounak, A.1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/nanophase-culns2-nanosheetscus-composite-grown-silar-method-leads-high-performance-counter-0
