EV Group, a leading supplier of coating equipment for the photovoltaics (PV), nanotechnology and semiconductor markets, and Brisbane Materials Technology (BMT), a specialty materials company, have announced they are collaborating to provide a total solution for anti-reflective (AR) coatings for the PV market.
The innovative technology enables the creation of a nano-porous silicon dioxide (SiO(2)) film from a liquid precursor at room temperature and atmospheric pressure, making this technology compatible with all existing PV-module and solar glass manufacturing lines.
The SiO(2) film is covalently bonded to the glass surface to give maximum durability and field reliability. The coatings have undergone rigorous testing to IEC 61215 standards, and have successfully completed a 2.5-year accelerated aging test equivalent to more than 20 years of field application.
The International Technology Roadmap for PV (ITRPV) specifies the introduction of AR coatings on solar cover glass beginning in 2013, and then moving into mainstream production going forward.
“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 5-6% 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.”
Added Dr. Thorsten Matthias, EV Group business development director, “Working with BMT will allow EVG to extend to the solar market the expertise in coating systems that we have built up over more than 15 years in the semiconductor and display industries. Together, we will be able to advance ITRPV requirements while quickly ramping to a high-volume manufacturing coating solution with greater flexibility, reliability and cost-effectiveness compared to competitive offerings.”
