Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Machine scores (provisional)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
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.

Abstract
Polymeric materials are promising for solar cell applications. High-molecular-weight and soluble poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4',7'-di- 2-thienyl-2',1',3'-benzothiadiazole)] is synthesized by either a Stille or Suzuki coupling reaction. Electrochemical and optical characterization of this thermally and air-stable polymeric material is reported, and bulk heretojunction polymer/fullerene photovoltaic devices are fabricated.
