三個(gè)世界第一，中國光伏產(chǎn)業(yè)領(lǐng)先世界

△央視財經(jīng)《經(jīng)濟半小時(shí)》欄目視頻

中國已經(jīng)向全世界作出重大承諾——2030年實(shí)現風(fēng)電、太陽(yáng)能發(fā)電總裝機容量達到12億千瓦以上，這意味著(zhù)，風(fēng)電加速發(fā)展的同時(shí)，中國太陽(yáng)能發(fā)電也將跑出加速度。

硅是太陽(yáng)能電池板最為重要的材料，硅的純度直接影響著(zhù)電池板的發(fā)電效率。四川的一家新能源公司提純硅的純度高達11個(gè)9（99.99999999999%）。

從硅料到一片可以真正用來(lái)發(fā)電的光伏電池，還需要歷經(jīng)很多個(gè)環(huán)節。單晶硅拉棒，硅片切割，這些過(guò)程往往在不同工廠(chǎng)進(jìn)行。這家工廠(chǎng)要在原有產(chǎn)線(xiàn)上，讓電池片的光電轉化效率再提高1.5%。
