Bulk Heterojunction Organic-Inorganic Photovoltaic Cell Based on Doped Silicon Nanowires

Goncher G., Noice L., Solanki R., Portland State University, US

A bulk heterojunction organic-inorganic photovoltaic cell was fabricated by growing doped n-type silicon nanowires on an n+ silicon substrate. A p-type organic semiconductor (P3HT) was then coated over the nanowires. The device was completed by [...]

Molecular Building Blocks for Efficient Solid State Lighting

Burrows P.E., Sapochak L.S., Pacific Northwest National laboratory, US

General illumination consumes 22% of the electricity generated in the U.S. This huge proportion is partly due to the ubiquity of artificial lighting but also the inefficiency of converting electrical energy to light. Incandescent lightbulbs [...]

Dynamics of Water in Nafion Fuel Cell Membranes: the Effects of

Moilanen D.E., Piletic I.R., Fayer M.D., Stanford University, US

The complex environment experienced by water molecules in the hydrophilic channels of Nafion membranes is studied by ultrafast infrared pump-probe spectroscopy. A wavelength dependent study of the vibrational lifetime of the O-D stretch of dilute [...]

Determination of Pore Size Distribution of Nafion/Sulfated beta-Cyclodextrin

Jeon J-D, Lee B.H., Kwak S-Y, Seoul National Univesity, KR

Direct methanol fuel cells are promising candidates for portable power sources and transport applications. One of the critical problems hindering the commercialization of DMFCs is high methanol permeation rate across proton-exchange membranes. In this study, [...]

Hydroxyapatite-imidazole-polymer composite films as a proton conductor under no humidified condition

Tsutsumi H., Hisha Y., Yamaguchi University, JP

We prepared the proton conduction system, hydroxyapatite (HAp)-imidazole (Im)-polymer composite films and investigated their structure, conduction behavior and mechanical properties. HAp particles used in our investigation were prepared with two different ways, a-HAp and n-HAp. [...]

Microbial fuel cell

Willert-Porada M., Lorenz K., Freitag R., Jerome V., Peiffer S., University of Bayreuth, DE

Polymer electrolyte fuel cells, PE-FC, use hydrogen or methanol as fuel. Water soluble organic compounds, like starch, glucose, acetates, can not serve as fuel because of limited catalytic activity of common metal catalysts. Opposite to [...]
