Capacitance measurements on ZnO/CdS/Cu(In/sub 1-x/Ga)Se/sub 2/ solar cells
Bibliographic record
Abstract
Capacitance-voltage (C-V) and deep level transient spectroscopy (DLTS) measurements have been carried out on heterojunction ZnO/CdS/Cu(In/sub 1-x/Ga/sub x/)Se/sub 2/ solar cells with different Ga content. These cells were fabricated on polished monocrystalline samples prepared by the Bridgman method. The C-V measurements indicated a significant effect of interface or surface states, especially for the non-annealed samples. Different hole deep levels and different shapes of DLTS spectrum were found in Cu(In/sub 1-x/Ga/sub x/)Se/sub 2/ crystals with different Ga content. It is believed that Ga content has a great impact in the formation of deep levels in Cu(In/sub 1-x/Ga/sub x/)Se/sub 2/ crystals. The DLTS results combined with the conversion efficiencies of the solar cells indicate the interfacial states could dominate the cell performance rather than the deep levels in the semiconductor.

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.
