该来源探讨了通过飞秒激光表面处理和热管理策略来提高太阳能热电发电机(STEG)性能的创新方法。文章详细阐述了如何对发电机冷热两侧进行光谱和热管理,以显著提升其功率输出。具体而言,它解释了使用飞秒激光处理钨(W)以创建选择性太阳能吸收器,从而最大限度地提高太阳能吸收并减少红外发射。此外,该研究还介绍了设计温室腔以进一步减少对流热损失。在冷侧,文章描述了如何使用飞秒激光将铝(Al)转换为微结构散热器,以增强对流和辐射冷却能力。最终,这些集成方法共同使STEG的功率输出增加了15倍,同时只增加了25%的重量,为无线传感器网络、可穿戴电子设备和医疗传感器等应用提供了紧凑高效的解决方案。内容来源:https://www.nature.com/articles/s41377-025-01916-9
