Why: Single-lab, single-paper proof-of-concept (Joule, published 2026-09-11, study titled "Submerged solar harvesting with wide-band-gap perovskites for autonomous underwater energy systems") with a genuine 5x depth advance over prior underwater photovoltaics (previously capped near 2 m), corroborated across techxplore, Interesting Engineering, ZME Science and PV Magazine, and including a real robotics/autonomy bridge (cells integrated with underwater robots for the field deployment) -- but validated by only ~2 hours of real open-sea operation; biofouling/corrosion durability and third-party replication remain open, so it is not yet mature enough to adopt or design around.
Next: Re-check in ~6 months for the team's planned deeper-depth trials (Zhang has speculated 20-30 m may be practically viable) or independent replication before considering any platform-facing reference to this technology.
