Solvent-free luminescent organic liquids for organic electronics

Researchers have introduced a new luminescent organic liquid that can be applied like ink. When two additional dyes are dissolved in this liquid, it forms a white luminescent paste that may offer a new way to make devices like large displays and white light-emitting diodes.

Novel 3D integration process flow: backside 'soft' via reveal

Imec presents a via-middle through-Si-via (TSV) approach to 3D stacking. This method is new to industry as it allows to 'reveal' TSV contacts by using a Si-etch process. The process further allows thinning down the wafers to 50um with a total thickness variation of less than 2um.

Process makes polymers truly plastic

Just as a chameleon changes its color to blend in with its environment, Duke University engineers have demonstrated for the first time that they can alter the texture of plastics on demand, for example, switching back and forth between a rough surface and a smooth one.

Nano-imprinted photonic structures improve efficiency of silicon solar cells

Imec has successfully fabricated crystalline silicon solar cells including 2D periodic photonic nanostructures made with nano-imprint lithography. The result was an improvement in energy-conversion efficiency, compared to unpatterned cells, through a better absorption of the light spectrum. The technique shows a path to further reducing the thickness of solar cells while keeping the efficiency as high as possible.

Researchers create more efficient hydrogen fuel cells

Hydrogen fuel cells, like those found in some "green" vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective. A research team from the University of Central Florida may have found a way around both hurdles.
