Stabilization methods for small molecule dewetting on indium tin oxide substrates for organic photovoltaics
Bibliographic record
Abstract
Heterojunctions are inherent in and essential to all molecular electronic devices. In organic solar cells, in particular, heterojunctions play a defining role in all of the major electrical processes and particularly in stability. The p-type organic molecule diindenoperylene (DIP) is an interesting photoactive organic molecule that forms inherently unstable interfaces within organic solar cell devices. Using scanning probe microscopies, supported by x-ray scattering, we examined the stability of inorganic/organic interfaces at both charge extraction electrodes. The DIP morphology can be stabilized by: 1. roughening the ITO surface, which disrupts the molecular packing, 2. using an interlayer such as PEDOT:PSS, which modifies the surface energy, or 3. depositing a dielectric layer, LiF, which pins the DIP grain boundaries. Any combination of the approaches would lead to significant improvements in solar cell lifetime.

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.
