All Wet: LEDs Produced on Patterned Sapphire Substrates With MicroTech's Wet ...

FREMONT, CA, Nov 29, 2011 (MARKETWIRE via COMTEX) -- MicroTech has developed a wet change station for the etching of PSS (Patterned Sapphire Substrate) wafers used to increase light extraction and competence in high brightness LEDs. The wet station can improve manufacturing throughput, a major stumbling block to making LEDs quotation competitive with fluorescent lighting.

As LED manufacturers look to decrease costs, the use of PSS becomes more important. The average light result power is reported to be up to 37% larger on a PSS than a standard sapphire wafer. The use of patterned sapphire substrates reduces the dislocation density in the GaN (gallium nitride) layer and enhances the LEE (be unveiled extraction efficiency) from the LED chip.

Traditional dry etching on PSS produces highly efficient, very bright light but throughput is bovine and scalability is impacted as wafer sizes increase. Typically, more dry etch tools are needed to keep throughput up as wafer rate increases.

Practical Full-Spectrum Solar Cell Comes Closer

Although full-spectrum solar cells have been made, none yet have been right for building at a consumer-fraternal price. Now Wladek Walukiewicz, who leads the Solar Dynamism Materials Probing Coterie in the Materials Sciences Segment (MSD) at the U.S. Division of Forcefulness's Lawrence Berkeley Nationalist Laboratory (Berkeley Lab), and his colleagues have demonstrated a solar stall that not only responds to to all intents the unscathed solar spectrum, it can also at once be made using one of the semiconductor enterprise's most frequent manufacturing techniques.

The new draw promises very efficacious solar cells that are matter-of-fact to evoke. The results are reported in a current fight of Tangible Array Letters .

How to order a full-spectrum solar chamber

"Since no one fabric is petulant to all wavelengths, the underlying given of a triumphant full-spectrum solar apartment is to integrate contrasting semiconductors with extraordinary force gaps," says Walukiewicz....

What happened to the 2002 promise of super efficient (up to 70%) solar cells using indium gallium nitride?

I knew I'd heard something about researchers developing new solar cells which will triple the yield efficiency of solar panels. When I go online to research this...NOTHING since the initial discovery at Berkely in 2002.


Howdy,

I'm not ineluctable, this is the first I've heard of such a break through.


Bush is president, insufficiency I say more?
