By contrast, photovoltaic solar power systems, mostly used on home rooftops, let light interact directly with semiconductor materials to generate power.

安装在住宅屋顶的太阳能光伏系统则与其相反，它让光线直接照射半导体材料以产生动力。

While many semiconductor materials can produce an electric potential when heated, through something called the Seebeck effect, that effect is very weak in carbon.

然而很多半导体材料(semiconductor material)在加热时能够通过塞贝克效应(Seebeck effect)这种形式产生电势能(electric potential)，但是在碳中发生的塞贝克效应很微弱。

By changing the composition of the semiconductor materials, it is possible to determine the amount of energy given up by each electron, and hence the light's colour.

改变半导体材料的构成可以改变电子能量释放的多少，从而改变光的颜色。

LEDs function by driving electrons across a junction between two semiconductor materials in which electrons move at different energy levels.
