South Korea's Hanhwa Q Cells and U.S. venture company 1366 Technologies (1366 Technologies) announced on March 5, 2015 that they have reached a cooperation agreement to develop high-performance, low-cost solar cells. The two companies will use the 1366 technology company's silicon wafer manufacturing technology "Direct Wafer" and other cooperative development. If the cooperative development is successful, both parties may expand cooperation to wafer supply and other aspects.
Direct Wafer is a technology that uses molten Si to directly manufacture polycrystalline silicon wafers. The technical details were not announced, but 1366 Technologies, when releasing the technology at the International Society for Solar Cells in October 2013, pointed out that the introduction of Si raw materials into the furnace can directly produce standard size solar cells. Compared with the original silicon wafer manufacturing process, manufacturing processes such as silicon germanium and wafer cutting are omitted, so that wafer manufacturing costs can be greatly reduced by half.
In March 2009, 1366 Technologies first used Direct Wafer to prototype small-size wafers. In June 2010, the wafer size was successfully increased to the industry standard 156mm square. Later, solar cells using silicon wafers manufactured using Direct Wafer gradually increased conversion efficiency. In August 2010, the unit conversion efficiency was only 14%, increased to 15% in July 2011, and further increased to 16% in March 2012.
In January 2013, silicon wafers were tested on four large-scale solar cell manufacturers with an annual production capacity of 1GW or more. As a result, the average cell conversion efficiency reached 17.1% (Jsc=35.0mA/cm2, Voc=618mV, FF=78.9). %). In July 2014, the highest value of unit conversion efficiency was increased to 18%.
1366 Technology Corporation announced that it will begin construction of a 250MW production facility in the United States in the third quarter of 2015. (Reporter: He Jiji)
Stainless Steel Crimped Wire Mesh is a beautiful, durable screen. Crimped wire mesh is made of a special process of Woven Steel Mesh . Stainless steel wire rolled out of wavy lines is weaved by wire mesh machine. Therefore, the hardware cloth surface smooth, firm and durable structure, strong impact resistance, abrasion resistance, low cost, and maintain uniform and beautiful. Stainless steel Crimped Wire Mesh is is an important classification of Woven Mesh Products. Crimped wire mesh can be deep processing, The new products derived from them also have a big market, such as our common Barbecue Wire Mesh, various Storage Basket , or mesh sieve and other filter products.
Due to the special properties of stainless steel, stainless steel Pressed Pattern Wire Mesh is often used in the industry with high stability requirements, the food industry for food basket, architectural decoration for decoration, automobile industry oil-water separator. It is Widely used in decoration, construction machinery, coal mines, cage, petroleum, chemical, construction, machinery accessories, protective nets, packaging wire cloth, BBQ mesh, barbecue net, sintering furnace with nets, metal products, handicraft net, vibration screen mesh, basket net, food machinery net, cooking food, roads, railways, infrastructure networks, can be used for solid material screening, use as a screen for liquid and slurry filtration, aquaculture, civil etc.
