Only a portion of the solar spectrum is useful for creating electricity from silicon based solar cells, with the remainder simply heating CPV systems and degrading their performance. With Cool Mirror Film 330, 3M utilized decades of expertise in manipulating wavelengths to ensure the film reflects only the light that can be absorbed by solar cells.
The development of Cool Mirror Film 330 is supported by advanced optics research dating back nearly 40 years. The company introduced reflective film technology in the 1960s, initially for application on windows. 3M unveiled its multilayer optical films in the 1990s for use in electronic displays, then optimized the technology for implementation in energy-efficient window films and concentrated solar systems.
The company worked closely with solar module manufacturer tenKsolar to optimize its multilayer optical film for low X CPV applications.
"The tenKsolar module design was a perfect fit with our Cool Mirror Film 330. It was truly a case of design synergy, one innovation meeting another innovation " said Dan Chen, Business Development Manager for 3M's Renewable Energy Division. "We are excited to work alongside inventive companies such as tenKsolar as we strive to improve the cost and performance of concentrated PV systems around the world."
3M multilayer optical films have been recognized with several prestigious awards with tributes to 3M scientists by the National Academy of Engineering, the Photonics Award of Excellence and the American Chemical Society Creative Invention Award.
