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，黑龍江太陽能電池片哪里便宜，使其慢慢擴(kuò)散，雜質(zhì)原子會(huì)慢慢的深入硅片中，黑龍江太陽能電池片哪里便宜，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，黑龍江太陽能電池片哪里便宜，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。晶硅太陽能電池片，每一片瓦數(shù)是多少？黑龍江太陽能電池片哪里便宜</p><div

太陽電池經(jīng)過制絨、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電池電極**普遍的一種生產(chǎn)工藝。 </p> <p> 對(duì)于太陽能電池來說，為了獲得盡可能高的光電轉(zhuǎn)化效率，對(duì)電池的結(jié)構(gòu)必須進(jìn)行詳細(xì)設(shè)計(jì)。金屬柵線負(fù)責(zé)把電池體內(nèi)的光生電流引到電池外部。太陽電池柵線的比較好設(shè)計(jì)是以電池總功率損耗**小為依據(jù)的。 </p> <p> 柵線結(jié)構(gòu)設(shè)計(jì)得好，將使電池的串聯(lián)電阻**小，從而使功率損耗**小、輸出功率比較大，這對(duì)大面積功率輸出的單體太陽能電池尤為重要。 </p> <p> 工藝上細(xì)柵線寬度的減小可以使所需的比較好細(xì)柵線間距減小，可以很大程度上減少頂層橫向電流總相對(duì)功率損耗和細(xì)柵線遮光相對(duì)功率損耗，從而減少電極引起的總的功率損耗。為了提高方阻的同時(shí)，降低由于電極引起的功率損耗，就需要增加細(xì)柵線條數(shù)、減小細(xì)柵線寬度。黑龍江太陽能電池片哪里便宜一個(gè)單晶電池片,多晶電池片分別有多少功率？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江太陽能電池片哪里便宜,太陽能電池片" src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188588692587891/8157481.jpg"></div><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(duì)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(duì)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 /> </p><p> 光伏電池的發(fā)電原理可說就是光伏發(fā)電原理： </p> <p> 光伏發(fā)電是利用半導(dǎo)體界面的光生伏***應(yīng)而將光能直接轉(zhuǎn)變?yōu)殡娔艿囊环N技術(shù)。這種技術(shù)的關(guān)鍵元件是太陽能電池。太陽能電池經(jīng)過串聯(lián)后進(jìn)行封裝保護(hù)可形成大面積的太陽電池組件，再配合上功率控制器等部件就形成了光伏發(fā)電裝置。 </p> <p> 光伏發(fā)電的主要具體原理是半導(dǎo)體的光電效應(yīng)。光子照射到金屬上時(shí)，它的能量可以被金屬中某個(gè)電子全部吸收，電子吸收的能量足夠大，能克服金屬內(nèi)部引力做功，離開金屬表面逃逸出來，成為光電子。硅原子有4個(gè)外層電子，如果在純硅中摻入有5個(gè)外層電子的原子如磷原子，就成為N型半導(dǎo)體；若在純硅中摻入有3個(gè)外層電子的原子如硼原子，形成P型半導(dǎo)體。當(dāng)P型和N型結(jié)合在一起時(shí)，接觸面就會(huì)形成電勢(shì)差，成為太陽能電池。當(dāng)太陽光照射到P－N結(jié)后，空穴由P極區(qū)往N極區(qū)移動(dòng)，電子由N極區(qū)向P極區(qū)移動(dòng)，形成電流。 </p> <p> 上面所說的光電效應(yīng)就是光照使不均勻半導(dǎo)體或半導(dǎo)體與金屬結(jié)合的不同部位之間產(chǎn)生電位差的現(xiàn)象。它首先是由光子(光波)轉(zhuǎn)化為電子、光能量轉(zhuǎn)化為電能量的過程；其次，是形成電壓過程。什么是太陽能電池片逆電流？</p><div style="width:100%;text-align:

目前光伏行業(yè)主流產(chǎn)品是P型硅片，P型硅片制作工藝簡單，成本較低，N型硅片通常少子壽命較大，電池效率可以做得更高，但是工藝更加復(fù)雜。N型硅片摻磷元素，磷與硅相溶性差，拉棒時(shí)磷分布不均，P型硅片摻硼元素，硼與硅分凝系數(shù)相當(dāng)，分散均勻度容易控制。 </p> <p>
