At Case Western Reserve University in Cleveland, Ohio, research scientists have designed a 4-inch silicon chip that holds 700 tiny primitive motors.

在俄亥俄州克利夫兰的凯斯西储大学，研究科学家设计了一种4英寸的硅片，可以容纳700个微型原始马达。

So rather than absorbing wavelengths more or less equally across a broad spectrum, as is the case in silicon, their prototype cell instead displays distinct absorption peaks.

以硅来说，并非穿过宽广的光谱吸收波长相同，他们的原电池反而明显地表现吸收峰值。

And the fact that this is also the case is very useful for making silicon.

But the silicon is what converts light into electricity, so you might think using so much less silicon would reduce the electrical output, but Atwater says that's not the case.
