3M Light Redirecting Film (LRF) for Solar Module Efficiency Improvement

Thumbnail for 3M Light Redirecting Film (LRF) for Solar Module Efficiency Improvement

3M Light Redirecting Film (LRF) is an engineered film that provides a new way to increase solar module power and energy output. LRF can be applied in non-active areas of the solar module during the assembly process to redirect light onto the active area of solar cells. By addressing the non-active portion of the solar module, in this case the tabbing ribbons, with durable optical films, module OEMs can achieve a 1.5-1.8% gain in power output irrespective of baseline cell efficiency.
