Looking at progress in computer chips , I dreamt about how cheap photovoltaic solar panels might become over the next 50 years .
看到人们在计算机芯片上取得的进展,我梦想着在未来50年光电太阳能电池板或许会变得非常廉价。
The compound is cheaper to use for photovoltaic material than silicon .
碲化镉是一种比硅更便宜的光伏材料。
This is not to say that big photovoltaic projects are finished .
这并不是意味着大型太阳能光伏发电项目已穷途末路了。
Most photovoltaic cells , such as those used in rooftop solar panels , use the semiconducting material silicon to convert the energy from photons of light to electricity .
大多数光电伏打电池,比如那些用在屋顶的太阳能电池板,利用半导体材料硅转化阳光中的光能为电能。
Plus , some of the intellectual property for concentrating photovoltaic , or pv , comes from the region .
除此之外,某些用于光电池领域的智能产品或峰值电压都来自于该地区。
Q-cells , based in wolfen , just north of leipzig , is the world 's biggest maker of the photovoltaic cells used in solar panels .
The research indicates that these facilities would add three or four cents per kwh to photovoltaic generation , bringing the total 2020 cost to eight or nine cents per kwh .
