太陽能電池需要一個大面積的PN結以實現光能到電能的轉換，而擴散爐即為制造太陽能電池PN結的**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，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。這種方法制出的PN結均勻性好,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結是太陽電池生產**基本也是**關鍵的工序。因為正是PN結的形成，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。太陽能電池片焊接問題！吉林晶澳太陽能電池片的尺寸</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構。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，還應在溶液中酌量添加醇類如乙醇和異丙醇等作為絡合劑，以加快硅的腐蝕。制備絨面前，硅片須先進行初步表面腐蝕，用堿性或酸性腐蝕液蝕去約20～25μm，在腐蝕絨面后，進行一般的化學清洗。經過表面準備的硅片都不宜在水中久存，以防沾污，應盡快擴散制結。北京硅太陽能電池片哪里便宜</p><p
