And the U.S. may yet do more: 1366 is working on a machine roughly the size of a dishwasher that will convert molten pure silicon directly into wafers for photovoltaics, rather than employing the process of sawing wafers from purified silicon logs as is commonly done today.
Rather than making transistors from conventional silicon wafers, they slice the material into sheets several times thinner than a human hair.
Moreover, the process required temperatures no higher than 120 °C, compared with many hundreds of degrees on a typical silicon wafer fabrication line, the team reports in ACS Nano.
For instance, the Lexington, Mass. — based 1366 Technologies received funds to develop its «monocrystalline equivalent» wafers that are formed directly from melted silicon rather than sawed from a block, which wastes as much as half of the semiconducting material.
The researchers had success in applying their technique to exotic wafer and semiconducting materials, including indium phosphide, gallium arsenenide, and gallium phosphide — materials that are 50 to 100 times more expensive than silicon.
The idea is that the film, when applied to different surfaces such as glass or brick, can produce solar energy more efficiently than conventional silicon wafer — based solar cells — which are made of materials similar to those used to fabricate computer chips.
Using a novel microscope that combines standard through - the - lens viewing with a technique called scatterfield imaging, the NIST team accurately measured patterned features on a silicon wafer that were 30 times smaller than the wavelength of light (450 nanometers) used to examine them.
It is even more automatizable to produce integrated circuits, than mechanical parts, as instead of doing precision engineering for joining together moving mechanical parts, you will only cut a silicon wafer!
SunPower claim they are starting production of silicon wafer chips with 23 % efficiency, but for more than $ 1 / w.
