As a result, photovoltaic cells placed near hot objects have only been able to generate around 0.02 watts per square centimetre.
因此，在发热物体附近放置的光伏电池每平方厘米只能够产生大约0.02瓦的电。
By contrast, photovoltaic cells absorbing sunlight can produce about 20 watts per square centimetre, provided the light is carefully concentrated using mirrors.
相对的，通过镜子汇聚太阳光，能够在光伏芯片上产生每平方厘米20w。
In 2002 IBM unveiled Millipede, a kind of computer memory that promises to store hundreds of gigabytes of data per square centimetre by punching nanoscale holes in a polymer sheet.
2002年，IBM发现了一种称之为Millipede的计算机内存，它承诺通过在一个聚合体薄片上钻一些纳米尺寸的小孔可以在每平方厘米实现几百千兆字节的数据存储。
This approach, which is being called micron-gap thermal photovoltaics (hence MTPV), is capable of generating 5-10 watts per square centimetre, a massive increase over what has been possible before.
这种被称为微米距热光电的新型光电元件（MTPV公司也就是因此而得名）每平方厘米能够产生5-10瓦的电量，这与普通光伏电池相比有了大幅增加。
