Abstract
Lattice matched III-V/Ge solar cells are mainstream for Concentrator PhotoVoltaics (CPV). Having both contacts on the back side could increase efficiency thanks to reduced shading and would provide an alternative to wire-bonding, shingling and MIMs as interconnections methods. In this paper, we present the first demonstration of back side contacted lattice matched III-V on Ge solar cell (InGaP/(In)GaAs/Ge). A specific process was developed to fabricate solar cells with a VOC of 2,38 V and a JSC of 9,9 mA/cm2. This result is a proof of concept and further developments should increase cell performance.

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 it
