- W3173851567 abstract "This article focuses on the plasmonic effect of gold nanoparticles incorporated in mesoporous TiO <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sub> photoanode for high efficiency dye-sensitized solar cells (DSSC). We have adopted a facile TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> posttreatment process for coating a thin TiO <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sub> shell over the gold nanoparticles. The device without TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> treatment and containing bare or uncoated gold nanoparticles exhibits a drop in efficiency compared to the control device. The cells fabricated with gold nanoparticles and posttreated with TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> show higher efficiencies than the control device. The improvement in efficiency is attributed to a higher value of photocurrent in the plasmonic devices arising due to the near-field enhancement effects. The TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> treated plasmonic cell provides a short-circuit current density (J <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>SC</sub> ) of 12.90 mA/cm <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> compared to 10.76 mA/cm <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> obtained from the control device. The overall power conversion efficiency is enhanced from 4.81% for the control DSSC to 5.71% for the TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> treated plasmonic DSSC. This plasmonic DSSC has also been compared with another type of plasmonic DSSC containing Au@SiO <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sub> core-shell nanoparticles. The photovoltaic performances of the two types of plasmonic DSSCs utilizing dielectric shell coated Au NPs are found to be similar, indicating the suitability of the TiCl <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sub> treatment for facile and reproducible fabrication of plasmonic solar cells." @default.
