美国加利福尼亚大学圣地亚哥分校研制了一种新型的纳米粒子材料,主要用于集中式太阳能发电,可将吸收光能的90%转换为热能。光吸收材料捕捉的光转换为电能或热能的总量是影响集中式太阳能发电效率的关键因素之一。该新型纳米粒子材料的尺寸为10nm~10μm,能够在高温下较长时间地保持相关性能,并具有较高的光能吸收率。研究人员对涂有该新型纳米粒子涂层的材料进行了热力学和机械性能测试,结果发现, University of California, San Diego, USA, has developed a new type of nanoparticle material that is mainly used for concentrated solar power generation, which converts 90% of the absorbed light energy into heat energy. The conversion of light captured by a light absorbing material to the total amount of electrical or thermal energy is one of the key factors that affect the efficiency of a centralized solar power generation. The new nanoparticle material has a size of 10 nm-10 μm, can maintain relative performance at high temperature for a long time, and has high light energy absorption rate. Researchers tested the thermodynamic and mechanical properties of the material coated with the new nanoparticle coating and found that,
