  • When I first heard about using particle accelerators to create solar panels, I thoughtwhat?!

    當我第一次聽說用粒子加速器來製造太陽能電池板時,我想......什麼?

  • I must not understand how solar panels are made. Or how particle accelerators work? And

    我一定不明白太陽能電池板是如何製造的。或者粒子加速器如何工作?還有

  • yes, there’s a key, unglamorous step thatunless youre fairly familiar with solar

    是的,有一個關鍵的、不光彩的步驟--除非你對太陽能相當熟悉

  • manufacturing technology (which I’m not) – you probably wouldn’t think of, and

    製造技術(我不是)--你可能不會想到,而

  • it’s in this step where a particle accelerator turns out to be useful: cutting silicon into

    粒子加速器正是在這一步驟中發揮了作用:將硅切割成

  • the really thin wafers that are the key component of a solar panel.

    真正薄的硅片是太陽能電池板的關鍵組成部分。

  • However, even this wasn’t at all what I first thought, which was something like slicing

    然而,即使是這樣,也完全不是我最初所想的那樣,也就是類似於切片的東西。

  • through the crystal with a super powerful particle beam. That sounds awesome, but the

    用超級強大的粒子束穿過水晶。這聽起來真棒,但

  • actual technique is much less insane and much more clever.

    實際的技術沒有那麼瘋狂,而是更加巧妙。

  • Ok, so a typical solar panel cell begins as a carefully grown cylinder of silicon atoms

    好的,所以一個典型的太陽能板電池開始是一個精心培育的硅原子圓柱體。

  • arranged in a regular crystal lattice, which are then trimmed and cut into wafer-thinwafers.

    在規則的晶格中排列,然後被修剪並切割成晶圓般薄的...晶圓。

  • Some of which retain curved corners as hallmarks of the original cylindrical crystal.

    其中一些保留了彎曲的角,作為原始圓柱形水晶的標誌。

  • Then the wafers get covered with other metals, anti-reflective coatings and electrodes, and

    然後,晶圓被其他金屬、抗反射塗層和電極覆蓋,並且

  • so on, to be able to capture the sun’s energybut the part we want to focus on is the

    等等,以便能夠捕獲太陽的能量 - 但我們要關注的部分是

  • cutting. Because when you cut something with a saw, like silicon wafers normally are, there

    切割。因為當你用鋸子切割東西時,像硅片通常是這樣,有

  • are two problems: one, you can't cut a slice too thin otherwise it might get brokentypical

    有兩個問題:第一,你不能把片子切得太薄,否則可能會被折斷--典型的

  • solar panel wafers are cut to about 0.15 millimeters. And two, unlike a knife which cuts by separating

    太陽能電池板晶片被切割到約0.15毫米。第二,與刀子不同,刀子是通過分離來切割的

  • and wedging two pieces of material apart, a saw cuts with teeth that gouge and eat away

    將兩塊材料夾開,鋸子用鋸齒切割,挖出並吃掉材料。

  • at the material, turning it into saw-dust and leaving a gap called a kerf. In the case

    在材料上,將其變成鋸末並留下一個稱為切口的間隙。在這種情況下

  • of silicon wafers, the gap is roughly the same width as the wafers themselves, which

    在硅片上,間隙的寬度與硅片本身的寬度大致相同,這就意味著

  • means about half of the original material goes to waste!

    意味著約有一半的原始材料被浪費掉了!

  • This is where particle accelerators come innot as a high powered ablative cutting particle

    這就是粒子加速器的作用:不是作為一種高能燒蝕切割粒子

  • beam, but by taking advantage of the physics of crystals. If instead you shoot protons

    晶體的物理特性,但是通過利用晶體的物理特性。如果你改成發射質子

  • with a certain energy at the flat face of the silicon cylinder, those protons will embed

    在硅圓柱體的平面上具有一定的能量,這些質子將嵌入到

  • themselves into the silicon. The depth depends on how much energy they have, and the thinner

    自己進入硅。深度取決於它們有多少能量,而越薄的

  • you want, the less energy they take, so you can easily pick something super thin. But

    你想要的東西,它們需要的能量就越少,所以你可以很容易地挑選一些超級薄的東西。但是

  • whatever thickness you choose, once inside the silicon crystal lattice, the protons kind

    無論你選擇什麼樣的厚度,一旦進入硅晶格,質子就會變成一種

  • of push it apart and create stress; if you heat the whole thing up, a wafer will break

    如果你把整個東西加熱,晶圓就會破裂。

  • right off, cleanly cleaving along the crystal lattice lines where the protons were. So,

    就這樣,沿著質子所在的晶格線乾淨地劈開。所以。

  • if after the protons are embedded, but before the heating, you glue this proto-wafer onto

    如果在質子嵌入之後,但在加熱之前,你把這個原晶圓粘在

  • a piece of glass or plastic, and then heat it up, you end up with a nice thin wafer of

    一塊玻璃或塑膠,然後將其加熱,你最終會得到一個漂亮的薄片。

  • silicon attached to a durable (and possibly flexible) material, with no waste silicon

    連接到耐用(可能是柔性)材料上的硅,沒有浪費硅。

  • whatsoever. To me, this is clever physics engineering!

    無論怎樣。對我來說,這就是聰明的物理工程!

  • Of course, a particle accelerator is much more expensive than a saw, so there must be

    當然,粒子加速器比鋸子要貴得多,所以必須有

  • some upsides to itthe biggest is that, by using significantly less silicon per wafer

    它有一些好處--最大的好處是,由於每塊晶圓使用的硅量大大減少

  • and not losing any silicon in the cutting process, it’s possible to justify using

    而且在切割過程中不會損失任何硅,是以有可能證明使用

  • much more expensive silicon that’s better at capturing sunlight, meaning the resultant

    昂貴得多的硅能更好地捕捉陽光,這意味著由此產生的

  • solar panels for a given power output are smaller and need less other material to make

    在一定的功率輸出下,太陽能電池板更小,需要更少的其他材料來製造。

  • them and hold them up, hence theyre cheaper. Hopefully enough cheaper to make up for the

    他們,並把他們舉起來,是以他們更便宜。希望能便宜到足以彌補

  • extra costs of using a particle accelerator to part silicon!

    使用粒子加速器分割硅的額外費用!

  • The company that’s trying to use the particle-accelerator technology I talked about in this video to

  • challenging and expensive endeavor and theyre looking for investors, so they sponsored this

    他們正在尋找投資者,所以他們贊助了這個項目。

  • mean, I’m neither an investment expert, nor a solar industry expertbut I do believe
