模塊制造：晶體硅（C-SI）后端

在組件制造過程中，太陽(yáng)能電池陣列被嵌入塑料薄膜片中，主要是醋酸乙烯酯( EVA )，并被封裝在前側(cè)的玻璃板和后側(cè)的耐候塑料背板之間，通常由聚氟乙烯( PVF )制成。

或者，對(duì)于一些特殊的應(yīng)用，后側(cè)也可以由玻璃板組成。然后將完整的夾層在150℃左右的溫度下在層壓機(jī)中進(jìn)行高壓烘烤。這里的關(guān)鍵點(diǎn)是將整個(gè)模塊均勻快速地加熱和加壓，以在EVA箔內(nèi)達(dá)到理想的交聯(lián)程度，以實(shí)現(xiàn)穩(wěn)定、長(zhǎng)期的模塊功能。

LayTec提供無損自動(dòng)化和完全集成的在線和離線計(jì)量，以控制封裝光伏組件的疊層質(zhì)量。

英文：

During module manufacturing, solar cell arrays are embedded in plastic film sheets, mainly ethyl vinyl acetate (EVA), and encased between a glass plate on the front side and a weather-resistant plastic back sheet on the rear, usually made of polyvinyl fluoride (PVF).
Alternatively, for some special applications the rear side may also consist of a glass plate. The complete sandwich is then baked in a laminator under high pressure at a temperature of around 150°C. The crucial point here is to heat and press the entire module uniformly and rapidly to reach an ideal cross-linking degree within the EVA foil for stable, long-term module function.

 LayTec offers non-destructive automated and fully integrated in-line and off-line metrology to control lamination quality of encapsulated PV modules.
