Structure‐Interface Synergistic Cu–Zn Hybrid Films for High‐Efficiency Thermal Management and Photothermal Conversion

. Moreover, it shows broadband absorption (200-800 nm) and exhibits rapid heating and steady state output under both broadband solar and UV irradiation, under 365 nm illumination the film warms to 91.3°C within 30 s, indicating a favorable steady state photothermal heating efficiency under the defined conditions. This strategy offers a scalable route for interface engineering of microscale metal fillers and thus couples' light absorption, heat transport, and energy use in solar-responsive and renewable energy conversion systems.
