What the current evidence supports

Human editorial judgment · 2026-07-21

Track; not yet

Why
Genuine peer-reviewed (Joule) efficiency record for an all-perovskite triple-junction architecture with a credible stability improvement mechanism (GO/SAM bilayer), but it is a single small-area lab cell with no independent certification and a stability window still far short of commercial requirements — a real scientific signal, not yet a deployable-technology signal.
Next
Re-check after (a) independent efficiency certification (NREL/Fraunhofer ISE/JET-listed) and (b) a follow-on publication or conference disclosure (e.g. EU PVSEC) showing module-scale cells or a stability result beyond ~1,000-2,000 hours; compare trajectory against the existing silicon-perovskite tandem entries already tracked (Trina, JinkoSolar) to see whether the all-perovskite path is closing the stability gap.
