Vindico Surface Technologies BV, a joint venture enterprise between Hardinxveld-Giessendam, has applied for a patent on Vindico PV+. According to the company, the technology is a combination of anti-reflective and hydrophilic technologies that has been independently proven to increase watt peak up to 5% or more.
The patent application has been submitted for a two-stage process that combines an anti-reflective coating with a durable, hydrophilic, dirt-repelling coating for use with photovoltaic glass used in the production of solar energy.
The two technologies used in producing PV+ are combustion chemical vapor deposition (CCVD) and a sol-gel coating. The CCVD process works by depositing silicon dioxide onto glass, creating an anti-reflective coating.
Application of Vindico HP, a sol-gel coating, over the CCVD technology process further enhances light transmission, the company adds. Sol-gels combine multiple chemical traits into a single coating for increased adhesion, durability and wear resistance. (Vindico HP has passed 50,000 abrasion tests with no effect.)
In addition to using Vindico HP in combination with the CCVD process, Vindico HP can be used as a contamination-reducing, hydrophilic coating on all types of photovoltaic glass and solar mirrors. By itself, Vindico HP can increase light transmission and reduce contamination by 50%.
