EV Group (EVG) and Brisbane Materials Technology (BMT) advised that their strategic cooperation agreement, has seen them collaborate on a total solution for anti-reflective (AR) coatings for the PV market. The agreement has seen EVG optimize its large-area coating systems for BMT’s materials and processes, leading to high-yield fabrication of AR coatings.
The companies noted that the technology allows for the creation of nano-porous silicon dioxide (SiO(2)) film from a liquid precursor at room temperature and atmospheric pressure. This is said to enable the technology to be compatible with all existing PV-module and solar glass manufacturing lines. The SiO(2) film is covalently bonded to the glass surface, which the companies say gives maximum durability and field reliability.
EVG and BMT note that the coatings have endured testing to IEC 61215 standards and completed a 2.5-year accelerated ageing test, equal to more than 20-years of field use. Further information on the materials technology and manufacturing equipment can be found at the companies shared booth, #5687, at Intersolar North America, July 10-12, in San Francisco.
“Our AR coatings improve the peak power output of PV modules by 3%, at the industry's lowest cost per square meter,” said Dr. Gary H. Wiseman, founder and CEO of BMT. “Our broadband AR coatings, with their excellent angular performance, should increase the energy output of a PV module by 5 to 6% or more when averaged over an entire day. Combining our unique materials technology with EVG's field-proven manufacturing systems allows us to provide a complete turnkey AR coating solution to customers.”
