Studies from Korea Basic Science Institute Describe New Findings in Applied Physics

June 24, 2014



By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Applied Physics. According to news reporting out of Pusan, South Korea, by VerticalNews editors, research stated, "TiO2 nanofibers (NFs) were fabricated by an electrospinning process and were used as scattering layers in dye-sensitized solar cells (DSSCs). The NF-coated photoanodes of the DSSCs were prepared with a variety of scattering layer thicknesses."

Our news journalists obtained a quote from the research from Korea Basic Science Institute, "The thickness effect of the scattering layer on the double-layered TiO2 nanoparticle (NP)/TiO2 NF structure was investigated through structural, morphological, and optical measurements. In the double-layered photoanode, the TiO2 NP layer plays a major role in dye adsorption and light transmission, and the TiO2 NF scattering layer improves the absorption of visible light due to the light scattering effects. The scattering effect of TiO2 NFs layer was examined by the incident monochromatic photon-to-electron conversion efficiency (IPCE) and UVeVis spectrometry."

According to the news editors, the research concluded: "The conversion efficiency for the 12 mm-thick photoanode composed of a 2 mu m-thick TiO2 NF layer and 10 mu m-thick TiO2 NP layer was higher than that of DSSCs with only TiO2 NPs photoanode by approximately 33%."
