Texas Engineering Experiment Station (TEES) and their partners will build a micro-CPV system that incorporates waveguide technology. A waveguide concentrates and directs light to a specific point. TEES's system uses a grid of waveguides to concentrate sunlight onto a set of coupling elements which employ a 45 degree turning mirror to further concentrate the light and increase the efficiency of the system. Each coupling element is oriented to direct its specific beam of light towards high-efficiency, multi-junction solar cells. Further system efficiency is gained by capturing diffuse light in a secondary layer. The system also includes a secondary layer that captures diffuse sunlight, increasing its overall efficiency.
If successful, innovations from TEES’s project may lower the cost of solar systems by enabling economical, high-volume manufacturing of micro-CPV arrays. Improved systems could encourage greater adoption of solar power in all three primary markets – residential, commercial, and utility.
Expanded use of clean, renewable solar power could reduce dependence on foreign sources of energy.
Solar power offers clean power generation with zero emissions. Technologies developed under MOSAIC may also enable solar installations with smaller physical footprints, reducing the environmental impacts of large solar arrays.
Technologies developed under MOSAIC could offer a cost-effective option for clean, locally produced power across all market sectors.
