这样使电池有机会吸收大部分照射到它的红端和蓝端的光线。

That gives it the opportunity to absorb, and thus convert into electricity, most of the red light falling on it, as well as the blue.

但是，黑色素的吸光度下降迅速，到光谱红端它几乎什么都不能吸收了。

But, melanin's absorbance falls down so rapidly that by the infrared end of the spectrum its hardly absorbing anything at all.

研究人员们使用仅仅超出可见光谱红端的近红外辐射测试他们的新“黑材料”。

The researchers tested their new black material with near-infrared radiation, just beyond the red end of the visible spectrum.
