vertically aligned single crystal tio2 nanowire arrays grown directly on transparent conducting oxide coated glass synthesis details and applications
Nano Letters, 2008Co-Authors: Xinjian Feng, Karthik Shankar, Oomman K Varghese, Maggie Paulose, Thomas J Latempa, Craig A GrimesAbstract:Single-crystal one-dimensional (1D) semiconductor architectures are important in materials-based applications requiring a large surface area, morphological control, and superior charge transport. Titania has widespread utility in applications including photocatalysis, photochromism, photovoltaics, and gas sensors. While considerable efforts have focused on the preparation of 1D TiO2, no methods have been available to grow crystalline nanowire arrays directly onto transparent conducting oxide (TCO) substrates, greatly limiting the performance of TiO2 photoelectrochemical devices. Herein, we present a straightforward low temperature method to prepare single crystal rutile TiO2 nanowire arrays up to 5 μm long on TCO glass via a Non-Polar Solvent/hydrophilic substrate interfacial reaction under mild hydrothermal conditions. The as-prepared densely packed nanowires grow vertically oriented from the TCO glass substrate along the (110) crystal plane with a preferred (001) orientation. In a dye sensitized solar c...

In a dye sensitized solar cell, N719 dye, using TiO2 nanowire arrays 2-3 microm long we achieve an AM 1.5 photoconversion efficiency of 5.02%.

thermoplasmonics assisted nanoheterostructured au decorated cuins2 nanoparticles matching solar spectrum absorption and its application on selective distillation of non polar Solvent systems by thermal solar energy
Nano Energy, 2015Co-Authors: Chia Wei Chen, Ming Fang, Yu Ze Chen, Yichung Wang, Chang Hong Shen, Jiamin Shieh, Johnny C Ho, Yulun ChuehAbstract:Abstract In this work, enhanced broadband solar spectrum absorption and solar-thermal conversion efficiency (~ 8%) has realized and reported by Au-decorated CuInS 2 nanoparticles, namely Au@CIS NPs. The morphologies, compositions and absorptions were characterized by high resolution transmission electron microscopy (HR-TEM), UV–vis spectrometer and Finite-Difference Time-Domain (FDTD) numeric methods. The Au@CIS NPs shows a distinguished absorption perfectly matching AM1.5 G solar spectrum, compared with pure Au, CIS and CIS–Au mixture nanoparticles (NPs) owing to near field plasmonic-assisted effect. In addition, the Au@CIS NPs proves its practical applications on selective distillation in Non-Polar Solvent systems, for which the selective distillation of methylcyclohexane from toluene as an example was demonstrated. The approach can evoke future developments of plasmonic-assisted heterostructure in nanoscale for thermal solar energy harvesting application.
