Chen N.H., Hsieh P-H, Huang F.S., Huang S-J, Huang F.S., Huang S-J, National Tsing Hua University, TW

The aim of this paper is to present a aluminum-based nonvolatile memory of Al2O3 (28 nm)/ Al-rich Al0.54O0.42N0.04 (22 nm)/ Al0.44O0.38N0.18 (3 nm) layered structure on SiO2 (2 nm)/ n-Si by a simple rapid thermal [...]

Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Wu K.R., Hung C.H., Yeh C.W., Sun J.C., Hsu C.J., National Kaohsiung Marine University, TW

In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Oxygen Reduction Reaction Enhancement of PdCo/C Electrocatalysts Driven by Oxidation Treatment

Wang K-W, National Central University, TW

One of the key issues for polymer electrolyte membrane fuel cells (PEMFCs) is to reduce or replace expensive Pt cathode catalysts. Although the development of non-Pt, such as Pd-Co catalysts for the oxygen reduction reaction [...]

Pt-Au Core/Shell Nanorods: Preparation and Applications as Electrocatalysts for Oxygen Reduction Reaction

Liu C-W, National Central University, TW

Nanostructured materials have been studied intensively due to their board potential applications in the energy field. A great deal of effort has been devoted to developing high efficient nanocatalysts for oxygen reduction reaction (ORR). In [...]

Sorption of Carbon Dioxide at High Temperatures by Slag

Tseng T.K., Chun K.L., Chu H., Chun K.L., National Cheng Kung University, TW

After industrial revolution, the increases of CO2 concentration in the atmosphere are resulted from the consumption of huge amounts of fossil fuels; hence causes global climate changes including temperature increasing and ocean level rising. Technologies [...]

Reduction of Collection Efficiency of Charge Carriers with Increasing Cell Size in Dye-Sensitized Solar Cell

Lee C-L, Lee W.H., Lee C-L, Lee W.H., Yang C-H, Yang H-H, Yang C-H, Yang H-H, National Cheng Kung University, TW

Changes in dye-sensitized solar cell performance related to active area size were investigated. The cell geometry was defined by introduction of a sub-electrode, which was uniform up to 4 cm2, and showed little change in [...]

The characterization of p-GaAs/i-InGaAsN/n-GaAs hetero-junction solar cell with various DMHy flow rates

Wu T.H., National Cheng Kung University, TW

Since the high efficiency tandem solar cell sturcture has been reported, the conversion efficiency of triple-junction solar cells would achieve 40% with concentrator. To further enhance the conversion efficiency of solar cells, the fourth-junction is [...]
