Abstract
Recently, all‐inorganic perovskite solar cells have attracted a large amount of attention, due to the much better water resistance compared to the organic counterparts. Unfortunately, the undesired phase transition remains a significant challenge, despite the many attempts. An important step forward is made here by numerical simulation, which discovers the significance of external strain to the stability of desired α‐CsPbI 3 , whose lifetime can be extended up to three times by nonhydrostatic tension, as is verified by both modeling and experimental results. In addition, such lifetime can be even enhanced further by hydrostatic tension, as indicated by the simulation. The unexpected observation provides not only an effective method to extend the lifetime of the perovskite devices, but also opens an unexpected path for the wide research community to utilize the straining engineering method that is extensively investigated in the perovskite research.

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
