Abstract
Scalable fabrication of perovskite solar cells (PSCs) in ambient air is important toward widespread industrial adoption. While spiro-OMeTAD-based PSCs perform well, they lack long-term stability, and alternative hole transport layers often trade efficiency for durability. Here we report high molecular weight poly(triarylamine) (HMW PTAA)-based PSCs fabricated in ambient air using scalable techniques, achieving 23.7% efficiency for 0.049 cm 2 solar cells and 22.2% for 10.23 cm 2 mini-modules, representing, to our knowledge, the highest values reported for scalable n-i-p PTAA-based perovskite photovoltaics made in ambient conditions. The HMW PTAA spontaneously forms a contact-area-reduced (CAR) interface with perovskite, enhancing charge collection and suppressing recombination. Despite reduced adhesion, the CAR interface improves PSC stability; devices retain 83% of their efficiency after 1000 h of operation at maximum power point at 55 ± 5 °C, and 77% after 1100 h of thermal stress at 85 °C. We attribute this resilience to strain-relieving interfacial voids created by the CAR interface.

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
