通过捕捉这样广泛的光波范围-比普通太阳能电池更广泛-串联胶体量子点太阳能电池原则上可以达到42%的效率。
By capturing such a broad range of light waves — wider than normal solar cells — tandem CQD solar cells can in principle reach up to 42 per cent efficiencies.
当光波进入普通材料时，如玻璃，这些材料改变了光波中的电磁场，使光波降低到某一新的速度。
When light waves enter normal materials such as glass, the material alters the electric and magnetic fields in the light, slowing the waves to a particular new speed.
在普通光束中，光波就像成群的人去观看足球比赛一样，互相拥挤和碰撞。
In an ordinary beam, the waves are like the pople in a crowd going to a football match, jostling and bumping into one another.
