Abstract
Abstract Chemical bath deposition (CBD) of tin oxide is a commercially viable method for manufacturing the electron transport layer in perovskite solar cells, yet it remains highly sensitive to reaction conditions, particularly pH . This study introduces tin‐like cation, namely Pb 2+ , as a chemical modulator to stabilize the CBD process. Due to nearly two orders of magnitude higher solubility of lead hydroxide (Pb(OH) 2 ) as compared to tin hydroxides (Sn(OH) 2 and Sn(OH) 4 ), Pb(OH) 2 acts as an OH − scavenger, reducing free excess OH − concentration and suppressing premature tin oxide (SnO x ) precipitation. This enables the formation of smooth, uniform SnO x films. Perovskite photovoltaics fabricated on these SnO x films via ambient and scalable processes achieve a power conversion efficiency of 24.5% for cells (and 17.8% for solar modules), retaining >84% of initial performance after 1000 h of operation under maximum power point tracking (MPPT) at 65 ± 5 °C.

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
