Abstract
Tremendous efforts have been devoted to facilitating the commercialization of perovskite solar cells (PSCs) in the past decade. However, the influence of solvent vapor atmosphere on PSC device performance during its fabrication still lacks related investigations. Here, by using three commonly employed solvent vapors during the perovskite annealing process, i.e., isopropanol, chlorobenzene and dimethylformamide, we reveal the effects of atmosphere on related perovskite film properties and device performance. The results indicate that perovskite films prepared under these external solvent vapors exhibit distinct crystalline phases, morphologies and optical properties from films under normal conditions (nitrogen gas), resulting in a significant drop in power conversion efficiency from the initial 20.01% to the lowest of only ~15%. Our work highlights the importance of atmospheric effects in preparing efficient PSCs for scalable fabrication and commercialization.

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
