Predict Light Injector efficiency and determine and flux
uniformity inside the cavity |
|
2) Based on Task 1 design system components and develop test
procedures |
Prepare CAD drawings for Light Injector and
Integrating Sphere for testing |
|
3) Fabricate System components including Light Injector,
Integrating Sphere for testing and assemble electronics |
Demonstrate that all components meet
specifications |
|
4) Setup test stand at NREL’s High Flux Solar Furnace facility in
Golden, CO |
Calibrate
Integrating Sphere for testing |
|
5) Conduct Prototype testing. a) Test
Light Injector b) Measure flux uniformity inside the Cavity |
1)
Demonstrate light throughput > 95% 2)
Demonstrate flux uniformity inside the cavity is within 10% |
|
6) Perform manufacturing cost analysis. |
Confirm from the project findings that the
projected manufacturing cost of the Light Injector supports the projected
solar electricity cost of $2/Watt |
