Designing Multifunctional Co and Fe Co-Doped MoS<sub>2</sub> Nanocube Electrodes for Dye-Sensitized Solar Cells, Perovskite Solar Cells, and a Supercapacitor
Bibliographic record
Abstract
In the present study, three types of specific solid, core–shell, and hollow structured cobalt and iron co-doped MoS2 nanocubes (denoted as s-Co-Fe-MoSx, c-Co-Fe-MoSx, and h-Co-Fe-MoSx) are controllably synthesized for the first time by regulating the reactant mass ratios. The prepared Co-Fe-MoSx nanocubes can function as a counter electrode in dye-sensitized and perovskite solar cells (DSCs and PSCs) and a working electrode in a supercapacitor. In the DSC system, the c-Co-Fe-MoSx nanocubes exhibit the maximum catalytic activity to the Co3+/2+ redox couple regeneration, and the device achieves a power conversion efficiency (PCE) of 8.69%, significantly higher than the devices using s-Co-Fe-MoSx (6.61%) and h-Co-Fe-MoSx (7.63%) counter electrodes. Similarly, all of the prepared Co-Fe-MoSx nanocubes show decent activity in PSCs and the device using the c-Co-Fe-MoSx counter electrode achieves the highest PCE of 6.88%. It is worth noting that, as the supercapacitor working electrode, the h-Co-Fe-MoSx exhibits a specific capacitance of 85.4 F g–1, significantly higher than the parallel values achieved by the s-Co-Fe-MoSx and c-Co-Fe-MoSx electrodes under identical conditions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
