Solar Generator with Two-Stage Optical Concentration Onto PV Cells

Case ID:

University of Arizona researchers have developed a photovoltaic (PV) solar power generator that leverages optical design principles to obtain high power conversion performance and the robustness of operation at lower cost.


As competition continues to grow within the solar power market, more efficient and less costly solar power systems are in high demand. This technology addresses that demand by providing a high performance optical design that focuses light onto multi-junction PV cells, thereby increasing efficiency and reducing cost for the power generated.



  • Small-to-medium scale solar power generation



  • Increased efficiency
  • Decreased cost of operation
