Proton irradiation effects on silicon heterojunction solar cells with MoOx selective contacts
Bibliographic record
Abstract
In this study, we investigate the effects of proton irradiation on silicon-based heterojunction and molybdenum oxide (MoO x ) selective contact solar cells. The main idea is to study their potential application in small satellites for measurement and monitoring. The irradiation dose simulates the aggressive environment found in Low Earth Orbit (LEO), where many satellites currently use Group III-VI (GaInP/GaAs/Ge) solar cells due to their superior efficiency, albeit at a higher cost. The experimental approach includes fabrication, irradiation, and characterization methods. Our results show a decrease in fill factor (F.F.) and overall efficiency after irradiation, mainly caused by a decrease in shunt resistance and an increase in series resistance. In addition, open-circuit voltage (V oc ) and short-circuit current (I sc ) may be affected by displacement damage defects caused by the irradiation process within the active region or by the formation of new point defects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
