半導(dǎo)體的摻雜擴散，主要是依靠了離子從高濃度像低濃度區(qū)域擴散的原理。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，安徽焊帶太陽能電池片功率，由此制出各式各樣的半導(dǎo)體器件。在一些無機固體化合物中摻入不同的金屬離子，安徽焊帶太陽能電池片功率，可以得到不同性質(zhì)的發(fā)光材料，安徽焊帶太陽能電池片功率，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。太陽能電池片漏電種類和原因分析！安徽焊帶太陽能電池片功率</p><div

太陽能電池需要一個大面積的PN結(jié)以實現(xiàn)光能到電能的轉(zhuǎn)換，而擴散爐即為制造太陽能電池PN結(jié)的**設(shè)備。管式擴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。擴散一般用三氯氧磷液態(tài)源作為擴散源。把P型硅片放在管式擴散爐的石英容器內(nèi)，在850---900攝氏度高溫下使用氮氣將三氯氧磷帶入石英容器，通過三氯氧磷和硅片進行反應(yīng)，得到磷原子。經(jīng)過一定時間，磷原子從四周進入硅片的表面層，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。因為正是PN結(jié)的形成，才使電子和空穴在流動后不再回到原處，這樣就形成了電流，用導(dǎo)線將電流引出，就是直流電。北京單晶硅太陽能電池片組件單晶硅片怎么制作成太陽能電池片？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽焊帶太陽能電池片功率,太陽能電池片"

style="text-indent:25px">1）太陽能光強。太陽能電池就是把太陽光轉(zhuǎn)化為電的一種器件，在一般的情況下（注意條件），太陽能電池的效率隨光強增加而增加的。再進一步說就是太陽能電池效率和安裝地的綜合氣候條件有關(guān)系。2）電池的材料。不同的材料對光的吸收系數(shù)不同，禁帶寬度也不同，量子效率自然也不同，電池效率自然也不同了。一般來說，單晶硅/多晶硅對光的系數(shù)系數(shù)遠小于非晶硅的，所以非晶硅太陽能電池厚度**有單晶硅/多晶硅厚度的百分之一即可較好的吸收太陽光。另外理論上講GaAs太陽能電池的極限效率要大于其他太陽能電池的極限效率，因為GaAs太陽電池的禁帶寬度在1.4ev，和地面太陽光光譜能量的**值**為接近。3）工藝水平。不同的工藝水平，電池的效率自然也不同，看看各個廠子就很明白了，為什么原材料幾乎都一樣，做出來的電池效率卻差別很大，原因就在這。工藝水平自然和設(shè)備水平有著重要的關(guān)系，一般來說設(shè)備越是先進工藝就越***，電池效率就越高（工藝是設(shè)備的產(chǎn)物，沒有設(shè)備工藝無法實現(xiàn)，都是空想）。典型的例子就是SiN:H減反膜以及倒金字塔結(jié)構(gòu)，一塊電池如果不采用這兩種工藝，效率差別會很**概8%左右）。</p><p> 太陽能電池發(fā)電原理: 太陽電池是一種對光有響應(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：單晶硅，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)電過程。 P型晶體硅經(jīng)過摻雜磷可得N型硅，形成P-N結(jié)。 </p> <p> 當(dāng)光線照射太陽電池表面時，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，在該電壓的作用下，將會有電流流過外部電路產(chǎn)生一定的輸出功率。這個過程的的實質(zhì)是：光子能量轉(zhuǎn)換成電能的過程。太陽能電池片連接問題！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽焊帶太陽能電池片功率,太陽能電池片" src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188253376865234/5608017.jpg"></div><p> 多晶硅太陽電他的出現(xiàn)主要是為了降低成本，其優(yōu)點是能直接制備出適于規(guī)?；a(chǎn)的大尺寸方型硅錠，設(shè)備比較簡單，制造過程簡單、省電、節(jié)約硅材料，對材質(zhì)要求也較低。晶界及雜質(zhì)影響可通過電池加工工藝進行改善；由于材質(zhì)和晶界影響，電池效率較低。電池工藝主要采用吸雜、鈍化、背場等技術(shù)。 </p> <p> 常規(guī)鋁吸雜工藝是在電池的背面蒸鍍鋁膜后經(jīng)過燒結(jié)形成，也可同時形成電池的背場。近幾年在吸雜上的工作證明，它對***單晶硅太陽電池及多晶硅太陽電池都會產(chǎn)生一定的作用。 </p> <p> 鈍化是提高多晶硅質(zhì)量的有效方法。一種方法是采用氫鈍化，鈍化硅體內(nèi)的懸掛鍵等缺點。在晶體生長中受應(yīng)力等影響造成缺點越多的硅材料，氫鈍化的效果越好。氫鈍化可采用離子注入或等離子體處理。在多晶硅太陽電池表面采用PECVD法鍍上一層氮化硅減反射膜，由于硅烷分解時產(chǎn)生氫離子，對多晶硅可產(chǎn)生氫鈍化的效果。 </p> <p> 在***太陽電池上常采用表面氧鈍化的技術(shù)來提高太陽電他的效率，近年來在光伏級的晶體硅材料上使用也有明顯的效果，尤其采用熱氧化法效果更明顯。使用PECVD法在更低的溫度下進行表面氧化，近年來也被使用，具有一定的效果。電池片有什么用？？？安徽焊帶太陽能電池片功率</p><p style="text-indent:25px">逆電流太陽能電池片有什么壞處？安徽焊帶太陽能電池片功率</p><p> 四、去磷硅玻璃 </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，以去除擴散制結(jié)后在硅片表面形成的一層磷硅玻璃。在擴散過程中，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)動系統(tǒng)、機械臂、電氣控制系統(tǒng)和自動配酸系統(tǒng)等部分組成，主要動力源有氫氟酸、氮氣、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為氫氟酸與二氧化硅反應(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一步與氫氟酸反應(yīng)生成可溶性的絡(luò)和物六氟硅酸。安徽焊帶太陽能電池片功率</p><p
