Project Description:
The purpose of this project is to research the feasibility of a high efficiency PV system that utilizes an omni-directional insect eye concentrator to direct light into a cavity that is lined with single junction solar cells that are coated such that they absorb a specific portion of the light spectrum and reflect the remainder of the spectrum to the other cells in the cavity.
Proposed Outcomes:
· Optimized system design that incorporates the concentrator, Rugate filters and single junction PV cells
· Feasibility analysis based on modeling and system design
Anticipated Benefits:
· Increase PV efficiency in converting solar energy into electricity from the current level of 8 – 16% to 38%.
· Reduce the installed cost of PV from $5 - $6/Watt to $1.50 - $3.00/Watt
