一个表面的反照率是入射的太阳能、阳光从这个表面反射回太空的百分比。
A surface's albedo is the percentage of incoming solar energy, sunlight, that's reflected off that surface back into space.
等离子体激元以这种方式水平地运动，比任何来自太阳的入射光线更多地经过太阳能电池的硅。
By travelling horizontally in this way, a plasmon passes through more of the solar cell's silicon than any incident beam from the sun could.
这其中关键在于折射最理想数目的光线，也就是让尽量多的光线转到能进入太阳能板的入射角度，而使尽量少的光线处于被反射掉的入射角度。
The key was bending the light the optimal amount, enough that it enters the solar panel at an angle, but not so much of an angle that the light reflects off and is lost.
