新冠封鎖期間，太陽能技術有了3個重大突破
Today, the world is grappling with more than just the climate crisis, and yet even now, in the face of a global pandemic, scientists are marching on with renewable solutions.
現在全世界要應對的不只有氣候危機。即使現在全球面臨疫情，科學家也在推進可再生能源解決方案。
Just this month, no less than three records have been broken in solar panel efficiency. The first and the second were achieved by scientists in the United States at the National Renewable Energy Laboratory (NREL).
就在本月，在太陽能電池板效率方面有多達三項紀錄被打破了。前兩項紀錄是國家可再生能源實驗室的美國科學家打破的。
Their unique "six-junction" solar cell has uNPRecedented energy conversion, turning intensified light into electricity at 47.1 percent efficiency - the most efficient in the world under concentrated light conditions. This record beat the previous contender established just a couple of years ago by one percent.
他們獨特的“六結”太陽能電池能進行前所未有的能量轉換，強光與電能的轉換效率是47.1%，是聚光條件下的全球最高效率。這個紀錄比幾年前的紀錄高出一個百分點。
"This device really demonstrates the extraordinary potential of multijunction solar cells," says John Geisz who works at NREL.
在國家可再生能源實驗室工作的John Geisz說：“這個設備真的展示了多結太陽能電池的非凡潛力。”
The achievement was helped by concentrating sunlight until it was a sizzling 143 times more intense. But even under the illumination of a single Sun, the solar cell is better than any other.
這是通過聚光使光照強度達到143倍實現的。但即使在不聚光的情況下，這種太陽能電池也比其他的要好。
This is the second record broken - the team tested another version of their six-junction cell without concentrating the light, and achieved an uNPRecedented 39.2 percent efficiency.
下面說說第二項被打破的記錄，該團隊在不聚光的情況下測試了另一種六結太陽能電池，效率達到了前所未有的39.2%。
Essentially this means that even more of the Sun's energy can now be converted into electricity.
基本上這就意味着現在有更多的太陽能可以被轉換成電能了。
The third record broken this month, for instance, was achieved by something called a tandem cell. This is a device, only a few micrometres thick, that combines two different semiconductors, one for the visible parts of the light spectrum and the other for infrared light.
比如本月打破的第三項紀錄是利用疊層電池實現的。這個設備只有幾微米厚，結合了兩種不同的半導體，一種用於光譜的可見部分，另一種用於紅外線。
Engineers from the German research centre Helmholtz-Zentrum Berlin created a new kind of tandem cell made from stacked silicon and perovskite with a certified efficiency of 24.16 percent.
德國研究中心亥姆霍茲柏林中心的工程師創造了一種新的疊層電池，由硅和鈣鈦礦疊層製成，認證效率爲24.16%。
