硅片是太陽(yáng)能電池片的載體，硅片質(zhì)量的好壞直接決定了太陽(yáng)能電池片轉(zhuǎn)換效率的高低，因此需要對(duì)來(lái)料硅片進(jìn)行檢測(cè)。該工序主要用來(lái)對(duì)硅片的一些技術(shù)參數(shù)進(jìn)行在線測(cè)量，這些參數(shù)主要包括硅片表面不平整度、少子壽命、電阻率、P/N型和微裂紋等。該組設(shè)備分自動(dòng)上下料、硅片傳輸、系統(tǒng)整合部分和四個(gè)檢測(cè)模塊。其中，光伏硅片檢測(cè)儀對(duì)硅片表面不平整度進(jìn)行檢測(cè),同時(shí)檢測(cè)硅片的尺寸和對(duì)角線等外觀參數(shù);微裂紋檢測(cè)模塊用來(lái)檢測(cè)硅片的內(nèi)部微裂紋;另外還有兩個(gè)檢測(cè)模組，其中一個(gè)在線測(cè)試模組主要測(cè)試硅片體電阻率和硅片類型，另一個(gè)模塊用于檢測(cè)硅片的少子壽命。在進(jìn)行少子壽命和電阻率檢測(cè)之前，需要先對(duì)硅片的對(duì)角線、微裂紋進(jìn)行檢測(cè)，并自動(dòng)剔除破損硅片。硅片檢測(cè)設(shè)備能夠自動(dòng)裝片和卸片，并且能夠?qū)⒉缓细衿贩诺焦潭ㄎ恢?，從而提高檢測(cè)精度和效率。吉林單晶太陽(yáng)能電池片哪里好太陽(yáng)能電池片**大功率是多少？</p><div

<p> 以n型半導(dǎo)體為底板結(jié)構(gòu)的結(jié)晶硅類太陽(yáng)能電池與以p型半導(dǎo)體為底板的結(jié)構(gòu)相比，前者對(duì)雜質(zhì)的抵抗性更大，在理論上更易提高能量轉(zhuǎn)換效率。不過(guò)，此前許多結(jié)晶硅類太陽(yáng)能電池幾乎都采用以p型半導(dǎo)體為底板的結(jié)構(gòu)。原因是在較厚的p型半導(dǎo)體上能夠形成非常薄的n型半導(dǎo)體層。 </p> <p> 德國(guó)弗勞恩霍夫太陽(yáng)能系統(tǒng)研究所（Fraunhofer ISE）宣布，該機(jī)構(gòu)研制的以n型半導(dǎo)體為底板，然后在其上面形成較薄的p型半導(dǎo)體層的單晶硅太陽(yáng)能電池，其能量轉(zhuǎn)換效率達(dá)到了23.4％。太陽(yáng)能電池單元面積為2cm見方。 </p><p> 太陽(yáng)能電池發(fā)電原理: 太陽(yáng)電池是一種對(duì)光有響應(yīng)并能將光能轉(zhuǎn)換成電力的器件。能產(chǎn)生光伏效應(yīng)的材料有許多種，如：?jiǎn)尉Ч?，多晶硅?非晶硅，砷化鎵，硒銦銅等。它們的發(fā)電原理基本相同，現(xiàn)已晶體硅為例描述光發(fā)電過(guò)程。 P型晶體硅經(jīng)過(guò)摻雜磷可得N型硅，形成P-N結(jié)。 </p> <p> 當(dāng)光線照射太陽(yáng)電池表面時(shí)，一部分光子被硅材料吸收;光子的能量傳遞給了硅原子，使電子發(fā)生了越遷，成為自由電子在P-N結(jié)兩側(cè)集聚形成了電位差，當(dāng)外部接通電路時(shí)，在該電壓的作用下，將會(huì)有電流流過(guò)外部電路產(chǎn)生一定的輸出功率。這個(gè)過(guò)程的的實(shí)質(zhì)是：光子能量轉(zhuǎn)換成電能的過(guò)程。太陽(yáng)能電池片連接問(wèn)題！</p><div

太陽(yáng)電池經(jīng)過(guò)制絨、擴(kuò)散及PECVD等工序后，已經(jīng)制成PN結(jié)，可以在光照下產(chǎn)生電流，為了將產(chǎn)生的電流導(dǎo)出，需要在電池表面上制作正、負(fù)兩個(gè)電極。制造電極的方法很多，而絲網(wǎng)印刷是目前制作太陽(yáng)電池電極**普遍的一種生產(chǎn)工藝。絲網(wǎng)印刷是采用壓印的方式將預(yù)定的圖形印刷在基板上，該設(shè)備由電池背面銀鋁漿印刷、電池背面鋁漿印刷和電池正面銀漿印刷三部分組成。其工作原理為：利用絲網(wǎng)圖形部分網(wǎng)孔透過(guò)漿料，用刮刀在絲網(wǎng)的漿料部位施加一定壓力，同時(shí)朝絲網(wǎng)另一端移動(dòng)。油墨在移動(dòng)中被刮刀從圖形部分的網(wǎng)孔中擠壓到基片上。由于漿料的粘性作用使印跡固著在一定范圍內(nèi)，印刷中刮板始終與絲網(wǎng)印版和基片呈線性接觸，接觸線隨刮刀移動(dòng)而移動(dòng)，從而完成印刷行程。什么是太陽(yáng)能電池片逆電流？吉林單晶太陽(yáng)能電池片哪里好</p><p

用來(lái)粘結(jié)固定鋼化玻璃和發(fā)電主體（如電池片），透明EVA材質(zhì)的優(yōu)劣直接影響到組件的壽命，暴露在空氣中的EVA易老化發(fā)黃，從而影響組件的透光率。 </p> <p> 從而影響組件的發(fā)電質(zhì)量除了EVA本身的質(zhì)量外，組件廠家的層壓工藝影響也是非常大的，如EVA膠連度不達(dá)標(biāo)，EVA與鋼化玻璃、背板粘接強(qiáng)度不夠，都會(huì)引起EVA提早老化，影響組件壽命。 </p> <p> 3、電池片主要作用就是發(fā)電，發(fā)電主體市場(chǎng)上主流的是晶體硅太陽(yáng)電池片、薄膜太陽(yáng)能電池片，兩者各有優(yōu)劣。 </p> <p> 4、EVA作用如上，主要粘結(jié)封裝發(fā)電主體和背板 </p> <p> 5、背板作用，密封、絕緣、防水（一般都用TPT、TPE等材質(zhì)必須耐老化，大部分組件廠家都質(zhì)保25年，鋼化玻璃，鋁合金一般都沒(méi)問(wèn)題，關(guān)鍵就在與背板和***是否能達(dá)到要求。） </p> <p> 6、鋁合金保護(hù)層壓件，起一定的密封、支撐作用 </p> <p> 7、接線盒保護(hù)整個(gè)發(fā)電系統(tǒng)，起到電流中轉(zhuǎn)站的作用，如果組件短路接線盒自動(dòng)斷開短路電池串，防止燒壞整個(gè)系統(tǒng)。 </p> <p> 8、*** 密封作用，用來(lái)密封組件與鋁合金邊框、組件與接線盒交界處。有些公司使用雙面膠條、泡棉來(lái)替代***，國(guó)內(nèi)普遍使用***，工藝簡(jiǎn)單，方便，易操作，而且成本很低。 </p> <p> 擴(kuò)展資料 </p> <p> <br /> 吉林單晶太陽(yáng)能電池片哪里好</p><p
