黑金属吸收光可用作太阳能热光伏系统的光吸收材料，该系统有望成为下一代的光伏系统。这里我们展示了由氦辐射形成的纤维状纳米结构钨从所有感兴趣的角度吸收光，在从可见光到近红外波长的太阳光谱中几乎是黑色的；对总太阳能的吸收率可以达到98%。揭示了这种纳米结构是通过一种新的过程形成的，即氦纳米气泡的自生长(C)2010日本应用物理学会
Black metal absorbing light can be used for the light absorber material for a solar thermophotovoltaic system, which is expected to be a photovoltaic system in the next generation Here we show that the fiberform nanostructured tungsten formed by helium irradiation absorbs the light from all angles of interest and is virtually black for a solar spectrum, from visible to near infrared wavelength; the absorptivity of the total solar power could be 98% It is revealed that the nanostructure is formed by a novel process, self-growth of the helium nano-bubbles (C) 2010 The Japan Society of Applied Physics
