Abstract
Abstract Organic photovoltaics have emerged as a low‐cost and sustainable technology suitable for integration into everyday life. Record power conversion efficiencies (PCE) are rising, having surpassed 18% for single‐junction devices. However, most work is still carried out using laboratory‐scale techniques and conditions which are not representative of what can be achieved in an industrial setting. Herein, the use of a high‐performance bulk‐heterojunction (BHJ) system (i.e., PM6:Y6C12) in fabricating devices with commercially available materials, with all organic layers slot‐die coated (hole transport layer, electron transport layer, and photoactive layer), without thermally treating the active layer, using non‐halogenated solvents, and in ambient condition is demonstrated. A conventional architecture is used, where the hole transport layer (PEDOT:PSS), the electron transport layer (PFNBr), and the photoactive layer (PM6:Y6C12), are all slot‐die coated in air from water, methanol, and o ‐xylene, respectively. Photovoltaic devices have an average efficiency of 10.1%, which is among the highest reported for devices with three slot‐die coated layers obtained in ambient conditions from halogen‐free solvents.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
