Solar interfacial evaporation is an emerging technology in solar energy harvesting developed to remedy the global energy crisis and the lack of freshwater resources. However, developing fully enhanced thermal management to optimize solar-heat utilization efficiency and form remains a great challenge. We created a synergistic photothermal layer from a poly(-phenylglycine) (PNPG)/MoS nanohybrid via electrostatic-induced self-assembly for a broad-spectrum and efficient solar absorption. The PNPG/MoS system provided effective synergistic photothermal conversion and good water transmission, enabling rapid solar steam escape. Notably, synergistic coupling of solar evaporation-thermoelectric (TE) power generation was also achieved, providing more efficient exploitation of solar heat. The system demonstrated a solar evaporation rate of up to 1.70 kg m h and achieved a maximum thermoelectric output power with 0.23 W m under one sun. The high-performance PNPG/MoS synergistic photothermal system developed in this study offers potential opportunities for coupling solar water purification with thermoelectric power generation to meet the needs of resource-scarce areas.
太阳能界面蒸发是一种新兴的太阳能收集技术，旨在应对全球能源危机和淡水资源短缺问题。然而，开发全面增强的热管理以优化太阳能利用效率和形式仍然是一个巨大的挑战。我们通过静电诱导自组装，从聚（对苯甘氨酸）（PNPG）/MoS纳米杂化物中创建了一个协同光热层，用于广谱高效的太阳能吸收。PNPG/MoS系统提供了有效的协同光热转换和良好的水传输性能，使太阳能蒸汽能够快速逸出。值得注意的是，还实现了太阳能蒸发-热电（TE）发电的协同耦合，从而更有效地利用太阳能热量。该系统的太阳能蒸发速率高达1.70 kg m² h⁻¹，在一个太阳光照下实现了0.23 W m⁻²的最大热电输出功率。本研究中开发的高性能PNPG/MoS协同光热系统为太阳能水净化与热电发电耦合提供了潜在机会，以满足资源稀缺地区的需求。
