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。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)孔透過漿料，用刮刀在絲網(wǎng)的漿料部位施加一定壓力，遼寧焊帶太陽能電池片分類，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，遼寧焊帶太陽能電池片分類。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，遼寧焊帶太陽能電池片分類，接觸線隨刮刀移動(dòng)而移動(dòng)，從而完成印刷行程。太陽能電池板的使用壽命是多長？遼寧焊帶太陽能電池片分類</p><div

由于在擴(kuò)散過程中，即使采用背靠背擴(kuò)散，硅片的所有表面包括邊緣都將不可避免地?cái)U(kuò)散上磷。PN結(jié)的正面所收集到的光生電子會(huì)沿著邊緣擴(kuò)散有磷的區(qū)域流到PN結(jié)的背面，而造成短路。因此，必須對太陽能電池周邊的摻雜硅進(jìn)行刻蝕，以去除電池邊緣的PN結(jié)。通常采用等離子刻蝕技術(shù)完成這一工藝。等離子刻蝕是在低壓狀態(tài)下，反應(yīng)氣體CF4的母體分子在射頻功率的激發(fā)下，產(chǎn)生電離并形成等離子體。等離子體是由帶電的電子和離子組成，反應(yīng)腔體中的氣體在電子的撞擊下，除了轉(zhuǎn)變成離子外，還能吸收能量并形成大量的活性基團(tuán)?；钚苑磻?yīng)基團(tuán)由于擴(kuò)散或者在電場作用下到達(dá)SiO2表面，在那里與被刻蝕材料表面發(fā)生化學(xué)反應(yīng)，并形成揮發(fā)性的反應(yīng)生成物脫離被刻蝕物質(zhì)表面，被真空系統(tǒng)抽出腔體。 </p><p> 一般來說，單個(gè)的太陽能電池不能直接作為電源使用，在實(shí)際應(yīng)用中，是將幾片或幾十片單個(gè)的太陽能電池串聯(lián)或并聯(lián)起來，組成太陽能方車，這樣才能得到較大的能力。在太陽能電池方陣中還裝有蓄電池，那是為了保證在夜晚或陰雨天太陽不露面時(shí)能連續(xù)供電的一種儲(chǔ)能裝置。當(dāng)太陽光照射時(shí)，太陽能電池產(chǎn)生的電能不停地滿足當(dāng)時(shí)的需要，而且還可多提供一些電能儲(chǔ)存于蓄電池內(nèi)。 </p> <p> 太陽能電池首先是在空間飛行中得到應(yīng)用的。1958年，美國發(fā)射了***顆太陽能電池供電的“先鋒”1號衛(wèi)星，從此，各式各樣的衛(wèi)星和宇宙飛船都安置了布滿太陽能電池的“翅膀”，使得它們能在太空中盡情遨游。由于衛(wèi)星和宇宙飛船上的電子儀器和設(shè)備都要使用大量的電能，但它們對電源的要求十分苛刻，既要重量輕，使用壽命長，能連續(xù)不斷地工作，又要能承受各種沖擊、碰撞和振動(dòng)的影響，而太陽電池在這幾方面都有出色的表現(xiàn)，自然而然便成了合適的中選者。當(dāng)衛(wèi)星向著太陽飛行時(shí)，電池方陣受陽光照射產(chǎn)生電能，供應(yīng)衛(wèi)生用電，同時(shí)向衛(wèi)星上的蓄電池充電；當(dāng)衛(wèi)星背著太陽飛行時(shí)，蓄電池就放電，使衛(wèi)星上的儀器保持連續(xù)工作。太陽能電池片2bb，3bb，4bb，5bb代表什么意思？</p><div

src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188253310683593/4469983.jpg"></div><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(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)有電流流過外部電路產(chǎn)生一定的輸出功率。這個(gè)過程的的實(shí)質(zhì)是：光子能量轉(zhuǎn)換成電能的過程。太陽能電池片帶電嗎？吉林非晶硅太陽能電池片進(jìn)口</p><p style="text-indent:25px">晶硅太陽能電池片，每一片瓦數(shù)是多少？遼寧焊帶太陽能電池片分類</p><p> 因?yàn)榻z網(wǎng)印刷的原因。 </p> <p> 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功率損耗和細(xì)柵線遮光相對功率損耗，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。遼寧焊帶太陽能電池片分類</p><p
