Herein, we report a robust, self\u2010powered photoelectrochemical (PEC) deep\u2010ultraviolet (DUV) photodetector based on an epitaxial La\u2010doped SrSnO\n                    <jats:sub>3<\/jats:sub>\n                    (LSSO)\/SrRuO\n                    <jats:sub>3<\/jats:sub>\n                    (SRO) architecture. The single\u2010crystalline epitaxial LSSO film and the high\u2010quality LSSO\/SRO interface suppress defect\u2010induced recombination and enable efficient separation and transport of photogenerated carriers. Through systematic optimization of La\u2010doping concentration and operating bias, the device achieves a remarkable peak responsivity of 459.84\u00a0mA W\n                    <jats:sup>\u22121<\/jats:sup>\n                    in natural seawater, alongside rapid response speeds (rise\/fall times of 2.98\/2.22\u00a0ms). The device shows excellent long\u2010term stability in natural seawater during PEC operation, with the photoactive surface directly exposed to the electrolyte. Specifically, the photocurrent remains nearly unchanged after 100 days of ambient storage and 30 days of immersion in natural seawater, retaining over 90% of its initial value after 2000 s of continuous cycling. This work demonstrates that epitaxial oxide thin films can effectively bridge the gap between high\u2010performance optoelectronics and harsh\u2010environment adaptability, paving the way for next\u2010generation deep\u2010sea exploration technologies.\n
