L’Oréal honours NUS women scientist

The excellent work of NUS researchers has been recognised by the 2014 L’Oréal Singapore For Women In Science National Fellowships. Two Fellows were presented with the awards, which come with a grant of $30,000 each, on 3 December.

Associate Professor Ho Ghim Wei from the Department of Electrical & Computer Engineering was accorded the Physical & Engineering Science fellowship for her research in “Functional Nanomaterials for Photocatalysis Solar Hydrogen Production”.

Assoc Prof Ho’s work focuses on the development of nanostructured materials for photocatalytic applications. The synergistic combinations of low-cost aqueous synthesis, band gap engineering and materials functionalisation have been employed to rationally design advanced photocatalyst for energy generation and pollutant degradation applications.

She said: “Through my innovation and impact, in both education and research in nanomaterial science and engineering, I hope to contribute to advances in health and environmental benefits and bring about greater recognition of the under-represented women in this field.”

Congratulations to Kevin Moe for winning the First Prize at the 2nd Graduate Student Symposium

Congratulations to Kevin Moe for winning the First Prize at the 2nd Graduate Student Symposium under the Microelectronic Technologies & Devices Track. His paper was titled “An Aqueous Route Towards 3-Dimensional Transparent Conducting Films on Glass for Photovoltaic Applications”. 14 winners were chosen from 180 presenters.


 

A/Prof Ho’s work on Energy was featured at NUS

A/P Ho Ghim Wei and her team focus their research in developing cost-effective three-dimensional transparent conductors using cheap aqueous method that can potentially replace conventional indium tin oxide (ITO) electrodes for displays, lighting, batteries to solar cells applications. The significant achievement can allow various electronics manufacturers to use the new design electrodes to make the same device at a lower cost and higher efficiency. This will greatly enhance the attractiveness of such unique electrodes in various electronics consumer market.


 

Kevin Moe’s work on Transparent Conducting Oxides was featured by Renewable Energy Global Innovations.

“Scientists from the National University of Singapore (NUS), one of the world’s leading university, have demonstrated that it is possible to replace ITO in dye sensitized solar cell (DSSC) with 3-dimensional transparent conductors (TC) fabricated using a cheap aqueous method. Dr Ho Ghim Wei and her team successfully fabricated Ga : ZnO films directly on glass substrates via a low-temperature aqueous route for application in dye-sensitized solar cells. Preliminary electrical and optical characterization of the films showed that 85% transparency across the optical range with sheet resistances as low as 15 Ωsq−1 were achievable, making them comparable to commercial transparent conducting oxides. Novel non-planar transparent conducting electrodes consisting of pillars, cross-hatched trenches and pit structures were fabricated to produce films with increased surface roughness and superior light scattering capabilities which are essential for photovoltaic applications. The work concludes with proof of concepts demonstrating the feasibility of large-scale fabrication and the compatibility of the electrodes for dye-sensitized solar cells. This significant achievement can allow various electronics manufacturers to use the newly-designed electrodes to make the same device at a lower cost and higher efficiency (50-70%). This will greatly enhance the attractiveness of such unique electrodes in various electronics consumer market.

“ITO is expensive so we decided to develop solution processable electrodes consisting of architectured 3D structures with tunable optical and electrical properties” said Dr Ho Ghim Wei, the Principal investigator and Assistant Professor at the Electrical and Computer Engineering Department at NUS. “The TCs are designed to effectively scatter light and transport photogenerated electrons through homojunction electrodes which enhance electrical performance” said Kevin Moe, a graduate student working on this project.

Current electronic devices uses ITO as the electrode fabricated using vacuum process, which is not cost-effective. By employing an aqueous route, it is possible to make large area TC for DSCC and other devices.

Their research paper entitled “Non-Planar Geometries of Solution Processable Transparent Conducting Oxide: From Film Characterization to Architectured Electrodes ”was published in the Energy and Environmental Science journal (DOI: 10.1039/C2EE21296J) earlier this year. The scientists have since shown efficiencies that have exceeded the published results. The NUS scientists are also exploiting the developed materials for new applications that will benefit from the low cost and scalable process.”
