Next generation of industrial silicon solar cells with efficiencies above 20%
Bibliographic record
Abstract
In order to make PV an economical source of energy, cell efficiencies have to be drastically increased. A new generation of high-efficiency crystalline silicon solar cells based on the OECO (obliquely evaporated contact) technology was introduced by us, using only few, simple and environmentally benign fabrication steps. In this paper progress of the OECO solar cells is presented. This includes the superior performance of the cells under realistic illumination conditions below 1 sun and at temperatures ranging from -40/spl deg/C to +80/spl deg/C. For the industrial size of 10/spl times/10 cm/sup 2/ record efficiencies up to 20% were achieved both on FZ-Si and on Ga-doped Cz-Si. This is the highest efficiency reported for large-area industrially feasible silicon solar cells. The custom-made construction of a 1 MW/year pilot line presently installed is outlined, demonstrating that economic and environmentally benign mass production of 20% efficient silicon solar cells is no vision any more.

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.
