Abstract
Silole-containing polymers consisting of a dithienosilole homopolymer backbone ( 12 ) or an alternating dithienosilole and 4,7-bis(2-thienyl)-2,1,3-benzothiadiazole copolymer backbone ( 13 ) were synthesized. The presence of planar dithienosilole tricyclic units along these π-conjugated polymer backbones lowered the band gap and led to strong absorption in the visible region of the solar spectrum. The introduction of electron-withdrawing benzothiadiazole moieties along the dithienosilole backbone further reduced the optical band gap and increased the interchain interaction. Bulk-heterojunction organic solar cells using 1:1 w/w polymer 12 or 13:PCBM (methanofullerene [6,6]-phenyl C61-butyric acid methyl ester) blends as the photoactive layers were prepared. Photovoltaic cells with copolymer 13 as the electron donor and PCBM as the electron acceptor exhibited an increased energy conversion efficiency by a factor of 3 up to 0.18% under an AM 1.5 simulated solar light at 100 mW/cm 2 after thermal annealing at 140 °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
