Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Too early to adopt

Why
A certified 34.82% cell-level record is genuinely state-of-the-art, but it is a lab cell with zero field-stability validation and no commercial product. The maturity gap between record cell and bankable module is the entire question, and it is unclosed.
Next
Track JinkoSolar + LONGi tandem roadmaps to a first certified commercial module spec (full-size, IEC-certified, warranted, with published degradation data); re-evaluate when a shippable tandem module appears (analyst consensus 2027-2028).
