Abstract

fetched live from OpenAlex

With the aim to find out an enhanced operating‐temperature range for photovoltaic device parameters, two types of the photoactive layer were prepared: poly(3‐hexylthiophene) (P3HT) and P3HT+nc‐TiO 2 (PTC) thin films. The enhancement obtained for the photoelectrical conversion efficiency of the composite based OSCs is attributed to the presence of nanoheterojunctions of TiO 2 /P3HT. For the temperature range of 30–70°C, the decrease of the open‐circuit potential was compensated by an increase of the fill factor; and the increase in the short‐circuit current resulted in an overall increase of the energy conversion efficiency. At elevated temperatures of 60–80°C the efficiency of the P3HT‐ and PTC‐based cells reached a maximum value of 1.6% and 2.1%, respectively. Over this temperature range the efficiency of P3HT‐based OSC decreased strongly to zero, whereas for the PTC cells it maintained a value as large as 1.2% at the temperature range of 110–140°C. The improved thermal stability of the composite‐based device was attributed to the lowered thermal expansion coefficient of the nanocomposite photoactive layer.

Teacher imitation

Not 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.
