光伏組件是太陽能發(fā)電系統(tǒng)的核心和重要組成部分。它的作用是將太陽能轉(zhuǎn)化為電能，送至蓄電池儲存，或推動負(fù)載工作。你知道什么因素會影響光伏發(fā)電組件發(fā)力嗎？

Photovoltaic module is the core and important component of solar power generation system. Its function is to convert solar energy into electric energy, send it to the battery for storage, or drive the load to work. Do you know what factors will affect the power generation of photovoltaic power generation modules?

1、防塵防雨的大型光伏電站一般建在戈壁地區(qū)，風(fēng)沙大，降水少。同時清潔頻率也不會太高。長期使用后效率損失在8%左右。

1. Large-scale photovoltaic power stations with dust and rain protection are generally built in the Gobi region, with heavy wind and sand and little precipitation. At the same time, the cleaning frequency will not be too high. The efficiency loss after long-term use is about 8%.

2、電池片開裂是電池的缺陷。由于晶體結(jié)構(gòu)的特點(diǎn)，晶體硅電池容易破碎。硅模塊的生產(chǎn)過程很長，很多環(huán)節(jié)都可能導(dǎo)致電池出現(xiàn)裂紋。開裂的根本原因可以概括為硅片的機(jī)械應(yīng)力或熱應(yīng)力。

2. Cracking of the battery is the defect of the battery. Due to the characteristics of crystal structure, crystalline silicon battery is easy to break. The production process of silicon module is very long, and many links may cause cracks in the battery. The root cause of cracking can be summarized as mechanical stress or thermal stress of silicon wafer.

3、PID效應(yīng)電位誘導(dǎo)衰減效應(yīng)是電池模塊長時間暴露在高電壓下，使玻璃和封裝材料之間產(chǎn)生漏電流，在電池表面產(chǎn)生大量電荷剪斷，惡化了電池表面的鈍化效果，導(dǎo)致模塊性能低于設(shè)計(jì)標(biāo)準(zhǔn)。PID現(xiàn)象嚴(yán)重時，會造成某個部件功率衰減50%以上，從而影響整個系列的功率輸出。高溫、高濕、高鹽度的沿海地區(qū)容易出現(xiàn)PID現(xiàn)象。

3. PID effect potential-induced attenuation effect is that the battery module is exposed to high voltage for a long time, resulting in leakage current between glass and packaging materials, and a large number of charge cuts on the battery surface, which worsens the passivation effect of the battery surface, resulting in the module performance lower than the design standard. When the PID phenomenon is serious, it will cause the power attenuation of a component to be more than 50%, thus affecting the power output of the whole series. PID phenomenon is easy to occur in coastal areas with high temperature, high humidity and high salinity.

部件PID現(xiàn)象有兩個主要原因：

There are two main reasons for component PID phenomenon:

(1)電池原因：電池方塊電阻的均勻性、減反射層的厚度和折射率對PID性能有不同的影響。

(1) Battery reason: the uniformity of battery block resistance, the thickness of antireflection layer and refractive index have different effects on PID performance.

(2)光伏組件原因：高溫高濕的外界環(huán)境導(dǎo)致電芯和接地框架之間產(chǎn)生漏電流，封裝材料、背板、玻璃和框架之間形成漏流通道。更換絕緣膜乙烯醋酸乙烯酯(EVA)是實(shí)現(xiàn)元器件防PID的途徑之一。在使用不同EVA包裝膜的條件下，元器件的抗PID性能會有所不同。此外，光伏組件中的玻璃主要是鈉鈣玻璃，玻璃對光伏組件PID現(xiàn)象的影響尚不清楚。

(2) Cause of PV module: the external environment of high temperature and humidity causes leakage current between the cell and the grounding frame, and leakage current channel is formed between the packaging material, backplane, glass and frame. Replacing the insulation film vinyl acetate (EVA) is one of the ways to realize the anti-PID of components. Under the condition of using different EVA packaging film, the anti-PID performance of components will be different. In addition, the glass in photovoltaic modules is mainly soda-lime glass, and the influence of glass on the PID phenomenon of photovoltaic modules is not clear.
