Role of the cathode interfacial layers in improving the stability of organic optoelectronic devices
Bibliographic record
Abstract
We study the photo-stability of various organic/metal contacts under monochromatic illumination. The results show that the organic/metal contacts are susceptible to irradiation, leading to deteriorations in both charge injection (i.e. from the metal to the organic layer) and charge extraction (i.e. from the organic layer to the metal). As a result, the photo-stability of these organic/metal contacts plays an important role in the stability of organic light-emitting devices (OLEDs), where the photo-degradation is caused by the irradiation of device own electroluminescence (EL), and organic photodetectors (OPDs), where exposure to light is obviously a more relevant issue. It is also found that interfacial layers such as cesium carbonate (Cs2CO3) and lithium acetylacetonate (Liacac) can greatly improve the photo-stability of the organic/metal contacts, and thus improve the stability of organic optoelectronic devices such as OLEDs and OPDs.

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.
