Technology Description:

George Washington University (GWU) and their partners will develop a hybrid CPV concept that combines highly efficient multi-junction solar cells and low-cost single-junction solar cells. When direct sunlight hits the lens array, it is concentrated 1000-fold and is focused onto the multi-junction solar cells. Diffuse light not captured in this process is instead captured by the low-cost single-junction solar cells. The module design is lightweight, fewer than 10 mm thick, and has a profile similar to conventional FPV. Moreover, the combination of the two types of cells increases efficiency. GWU will use its expertise in micro-transfer printing to fabricate and assemble the multi-junction cells. This process will reduce manufacturing costs and further increase efficiency.

Potential Impact:

If successful, innovations from GWU in this project may lower the cost of solar systems by allowing 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

Security:

Expanded use of clean, renewable solar power could reduce dependence on foreign sources of energy.

Environment:

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.

Economy:

Technologies developed under MOSAIC could offer a cost-effective option for clean, locally produced power across all market sectors.
