Thin Silicon are more efficient than thicker wafers.
Boston, MA (PRWEB) April 15, 2013
UniversityWafer.com is proud to introduce super-thin Silicon wafers. UniversityWafer, Inc. now distributes thin silicon wafers that are 2 microns thick! The thickness of of a human hair is 100 microns. Researchers can purchase as few as one wafer to experiment with.
The main application for thin wafers is sensors of all types. To handle these thin wafers, it is recommended that Teflon coated tweezers or vacuum wand /tweezers be used. Teflon is used for the same reason chefs use it for cooking, for its no stick properties. Such thin wafers can stick to other surfaces including metal and glass and could be damaged when pulled off.
Other uses for thin silicon include very thin devices that are mass produced including smart cards and smart labels. Many firms and universities do not possess the expertise and or equipment to dice larger diameter thin wafers into into chips. Universitywafer.com can help and offers 2 micron thin wafers that are only 5mm square. Other smaller dimensions are also available upon request.
Thin silicon can also be used for solar applications. Below 50 micron silicon becomes flexible to a point. Thus a wafer of say 100mm square or round can wrap around a cylinder or ball. This flexibility can allow researchers to experiment with alternative power sources for autonomous vehicles such as Unmanned Aerial Vehicles (UAVs) which require rounded surfaces for aerodynamic purposes and to save on weight.
Some experiments have show than 100um thin moocrystalline silicon can be three times more efficient in converting the sun rays into electricity than conventional solar wafers used today. Conventional cells currently average 14% efficiency. 100um thin solar cells can potentially see 45% efficiency. The major drawback to thinner siliconcells is the much greater costs.
UniversityWafer.com believe that current costs would be negated by the savings in future cost of real estate. Going forward, as land becomes scarcer, higher efficiency solar cells would be required that can generate three times as much power for a given space.
Above are just some advantages of super thin silicon wafers sold by UniversityWafer.com.
