src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188251315625000/557153.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(jìn)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(jìn)行表面氧化，近年來也被使用，具有一定的效果。 </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2bb，3bb，4bb，5bb代表什么意思？</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(jìn)行反應(yīng)，得到磷原子。經(jīng)過一定時間，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。一個單晶電池片,多晶電池片分別有多少功率？北京焊帶太陽能電池片好壞</p><p

單晶硅絨面的制備是利用硅的各向異性腐蝕，在每平方厘米硅表面形成幾百萬個四面方錐體也即金字塔結(jié)構(gòu)。由于入射光在表面的多次反射和折射，增加了光的吸收，提高了電池的短路電流和轉(zhuǎn)換效率。硅的各向異性腐蝕液通常用熱的堿性溶液，可用的堿有氫氧化鈉，氫氧化鉀、氫氧化鋰和乙二胺等。大多使用廉價的濃度約為1%的氫氧化鈉稀溶液來制備絨面硅，腐蝕溫度為70-85℃。為了獲得均勻的絨面，還應(yīng)在溶液中酌量添加醇類如乙醇和異丙醇等作為絡(luò)合劑，以加快硅的腐蝕。制備絨面前，硅片須先進(jìn)行初步表面腐蝕，用堿性或酸性腐蝕液蝕去約20～25μm，在腐蝕絨面后，進(jìn)行一般的化學(xué)清洗。經(jīng)過表面準(zhǔn)備的硅片都不宜在水中久存，以防沾污，應(yīng)盡快擴散制結(jié)。北京焊帶太陽能電池片好壞</p><p
