China

Natcore Technology’s antireflective coating technology was independently validated by Chinese solar cell manufacturer, Hunan TLNZ Solar Technology. Natcore researchers in Ohio prepared and sent numerous silicon wafers with the company’s antireflection coating to Hunan, who was selected by the Chinese government to complete the cell finishing and conduct testing. All the wafers were coated with Natcore’s liquid based deposition technology and were examined for composition and quality by Hunan, who then added metal front and back contacts to the cells and proceeded to test their efficiency. Per Hunan, cell efficiencies reached as high as 15 per cent during the initial testing for the AR coating and the solar cell manufacturer noted that the standard deviation of efficiencies for all the cells was within the normal industry accepted limit.
