Abstract

fetched live from OpenAlex

In order to get an air stable solar cell with high open circuit voltage (Voc), we fabricated an inverted tandem solar cell based on hybrid wet chemistry and vacuum thermal deposition techniques. A thin metallic interfacial layer was applied to improve charge recombination and maximize both the fill factor and Voc of the tandem solar cell. A cationic dye doped electron transport layer was used to minimize space charge induced Voc loss. The tandem cell Voc reached 1.02 V, which equals the sum of the two subcells’ Voc. Increase of the metal nanoparticles’ layer thickness reduces the short circuit current density of the tandem owing to increasing light extinction. Our tandem cell design offers superior air stability due to additional encapsulation effect from top metal oxide layers. It retains about 80% of its original efficiency after storage in air for three months.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
