Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion
Bibliographic record
Abstract
Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications owing to their non‐toxic and high solar absorption properties. However, unanticipated structural distortion within these materials can compromise their performance, suppressing the structural distortion is essential and remains challenging. Here, it is reported that using phenylethylamine triggering the disorder‐order phase transition can largely increase the ordering extent of octahedra in double perovskite Cs 2 AgBiBr 6 , which can suppress self‐trapped exciton and defect and enable rapid charge separation, leading to exceptional photo‐physics/chemistry properties with over sixfold photoactivity enhancement in the photocatalytic C−H bond activation compared to less ordered structures. This work provides an effective strategy to solve the challenging problem of the disorder phenomenon of halide double perovskites for boosting solar‐to‐chemical energy conversion.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
