src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188251315625000/557153.jpg"></div><p> 太陽能電池片加工中的摻雜與擴(kuò)散原理的原理： </p> <p> 半導(dǎo)體的摻雜擴(kuò)散，主要是依靠了離子從高濃度像低濃度區(qū)域擴(kuò)散的原理。在太陽能的硅片中，把雜質(zhì)原子的氣相源靠近硅片，加熱后，使其慢慢擴(kuò)散，雜質(zhì)原子會慢慢的深入硅片中，濃度從硅片邊緣到內(nèi)部是逐漸降低的。 </p> <p> <br /> </p> <p> 半導(dǎo)體中的摻雜是指在半導(dǎo)體硅中摻入磷或鎵可以得n型或p型半導(dǎo)體材料，由此制出各式各樣的半導(dǎo)體器件。在一些無機(jī)固體化合物中摻入不同的金屬離子，可以得到不同性質(zhì)的發(fā)光材料，如氧化釔(III)中摻入銪(III)離子可以得到發(fā)紅光的熒光材料。安徽硅太陽能電池片功率太陽能電池片Eta17.9%代表什么？</p><div

通常的晶體硅太陽能電池是在厚度350～450μm的高質(zhì)量硅片上制成的，這種硅片從提拉或澆鑄的硅錠上鋸割而成。因此實(shí)際消耗的硅材料更多。為了節(jié)省材料，人們從70年代中期就開始在廉價(jià)襯底上沉積多晶硅薄膜，但由于生長的硅膜晶粒大小，未能制成有價(jià)值的太陽能電池。為了獲得大尺寸晶粒的薄膜，人們一直沒有停止過研究，并提出了很多方法。目前制備多晶硅薄膜電池多采用化學(xué)氣相沉積法，包括低壓化學(xué)氣相沉積（LPCVD）和等離子增強(qiáng)化學(xué)氣相沉積（PECVD）工藝。此外，液相外延法（LPPE）和濺射沉積法也可用來制備多晶硅薄膜電池?；瘜W(xué)氣相沉積主要是以SiH2Cl2、SiHCl3、Sicl4或SiH4,為反應(yīng)氣體,在一定的保護(hù)氣氛下反應(yīng)生成硅原子并沉積在加熱的襯底上，襯底材料一般選用Si、SiO2、Si3N4等。 </p><p> 太陽能電池的輸出功率一方面與外部環(huán)境有關(guān)，另一方面與負(fù)載情況有關(guān)，因此光伏電池輸出功率必須加以控制，使它在各種情況下都輸出比較大的功率。 </p> <p> 1、電池測試：電池測試即通過測試電池的輸出參數(shù)的大小對其進(jìn)行分類，以提高電池的利用率，做出量合格的電池組件。 </p> <p> 2、正面焊接：是將匯流帶焊接到電池正面（負(fù)極）的主柵線上，匯流帶為鍍錫的銅帶，將焊帶以多點(diǎn)的形式點(diǎn)焊在主柵線上。 </p> <p> 3、背面串接：背面焊接是將3 </p> <p> 6片電池串接在一起形成一個(gè)組件串。 </p> <p> 4、層壓敷設(shè)：背面串接好且經(jīng)過檢驗(yàn)合格后，將組件串、玻璃和切割好的EVA 、玻璃纖維、背板按照一定的層次敷設(shè)好，準(zhǔn)備層壓。玻璃事先涂一層試劑（primer）以增加玻璃和EVA的粘接強(qiáng)度。敷設(shè)時(shí)保證電池串與玻璃等材料的相對位置，調(diào)整好電池間的距離，為層壓打好基礎(chǔ)。 </p> <p> 5、件層壓：將敷設(shè)好的電池放入層壓機(jī)內(nèi)，通過抽真空將組件內(nèi)的空氣抽出，然后加熱使EVA熔化將電池、玻璃和背板粘接在一起，***冷卻取出組件。 </p> <p> 6、修邊：層壓時(shí)EVA熔化后由于壓力而向外延伸固化形成毛邊，所以層壓完畢應(yīng)將其切除。 </p> <p> 7、裝框：類似與給玻璃裝一個(gè)鏡框，給玻璃組件裝鋁框，增加組件的強(qiáng)度，進(jìn)一步的密封電池組件，延長電池的使用壽命。 </p> <p> <br /> 太陽能電池片的分類及其優(yōu)缺點(diǎn)是什么？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

太陽能電池需要一個(gè)大面積的PN結(jié)以實(shí)現(xiàn)光能到電能的轉(zhuǎn)換，而擴(kuò)散爐即為制造太陽能電池PN結(jié)的**設(shè)備。管式擴(kuò)散爐主要由石英舟的上下載部分、廢氣室、爐體部分和氣柜部分等四大部分組成。擴(kuò)散一般用三氯氧磷液態(tài)源作為擴(kuò)散源。把P型硅片放在管式擴(kuò)散爐的石英容器內(nèi)，在850---900攝氏度高溫下使用氮?dú)鈱⑷妊趿讕胧⑷萜?，通過三氯氧磷和硅片進(jìn)行反應(yīng)，得到磷原子。經(jīng)過一定時(shí)間，磷原子從四周進(jìn)入硅片的表面層，并且通過硅原子之間的空隙向硅片內(nèi)部滲透擴(kuò)散，形成了N型半導(dǎo)體和P型半導(dǎo)體的交界面，也就是PN結(jié)。這種方法制出的PN結(jié)均勻性好,方塊電阻的不均勻性小于百分之十,少子壽命可大于10ms。制造PN結(jié)是太陽電池生產(chǎn)**基本也是**關(guān)鍵的工序。因?yàn)檎荘N結(jié)的形成，才使電子和空穴在流動(dòng)后不再回到原處，這樣就形成了電流，用導(dǎo)線將電流引出，就是直流電。太陽能電池片為什么有細(xì)柵線?北京焊帶太陽能電池片柵線</p><p

該工藝用于太陽能電池片生產(chǎn)制造過程中，通過化學(xué)腐蝕法也即把硅片放在氫氟酸溶液中浸泡，使其產(chǎn)生化學(xué)反應(yīng)生成可溶性的絡(luò)和物六氟硅酸，以去除擴(kuò)散制結(jié)后在硅片表面形成的一層磷硅玻璃。在擴(kuò)散過程中，POCL3與O2反應(yīng)生成P2O5淀積在硅片表面。P2O5與Si反應(yīng)又生成SiO2和磷原子，這樣就在硅片表面形成一層含有磷元素的SiO2，稱之為磷硅玻璃。去磷硅玻璃的設(shè)備一般由本體、清洗槽、伺服驅(qū)動(dòng)系統(tǒng)、機(jī)械臂、電氣控制系統(tǒng)和自動(dòng)配酸系統(tǒng)等部分組成，主要?jiǎng)恿υ从袣浞帷⒌獨(dú)?、壓縮空氣、純水，熱排風(fēng)和廢水。氫氟酸能夠溶解二氧化硅是因?yàn)闅浞崤c二氧化硅反應(yīng)生成易揮發(fā)的四氟化硅氣體。若氫氟酸過量，反應(yīng)生成的四氟化硅會進(jìn)一步與氫氟酸反應(yīng)生成可溶性的絡(luò)和物六氟硅酸。北京焊帶太陽能電池片柵線</p><p
