由于在擴散過程中，即使采用背靠背擴散，硅片的所有表面包括邊緣都將不可避免地擴散上磷。PN結(jié)的正面所收集到的光生電子會沿著邊緣擴散有磷的區(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完成這一工藝。等離子刻蝕是在低壓狀態(tài)下，反應氣體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?；钚苑磻鶊F由于擴散或者在電場作用下到達SiO2表面，在那里與被刻蝕材料表面發(fā)生化學反應，并形成揮發(fā)性的反應生成物脫離被刻蝕物質(zhì)表面，被真空系統(tǒng)抽出腔體。單晶硅片怎么制作成太陽能電池片？黑龍江薄膜太陽能電池片生產(chǎn)</p><p style="text-indent:25px">太陽能電池板的種類?。?！遼寧焊帶太陽能電池片哪里好</p><p> 三、擴散制結(jié) </p> <p> 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，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型半導體和P型半導體的交界面，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，用導線將電流引出，就是直流電。遼寧焊帶太陽能電池片哪里好</p><p
