id="2fwtfht" class="box"><p><p> 因為絲網印刷的原因。 </p> <p> 太陽電池經過制絨、擴散及PECVD等工序后，已經制成PN結，可以在光照下產生電流，為了將產生的電流導出，需要在電池表面上制作正、負兩個電極。制造電極的方法很多，而絲網印刷是目前制作太陽電池電極**普遍的一種生產工藝。 </p> <p> 對于太陽能電池來說，為了獲得盡可能高的光電轉化效率，對電池的結構必須進行詳細設計。金屬柵線負責把電池體內的光生電流引到電池外部。太陽電池柵線的比較好設計是以電池總功率損耗**小為依據的。 </p> <p> 柵線結構設計得好，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，吉林雙晶硅太陽能電池片廠家，這對大面積功率輸出的單體太陽能電池尤為重要。 </p> <p> 工藝上細柵線寬度的減小可以使所需的比較好細柵線間距減小，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，吉林雙晶硅太陽能電池片廠家，吉林雙晶硅太陽能電池片廠家，降低由于電極引起的功率損耗，就需要增加細柵線條數、減小細柵線寬度。太陽能電池片經過幾道工序生產？吉林雙晶硅太陽能電池片廠家</p><div

W/m2時，當電池表面溫度為50℃時，**大功率點發(fā)生在電壓為380V處，溫度為25℃時，**大功率點發(fā)生在電壓為520V處。由此可知，如果不采用控制方法，當光照強度和溫度發(fā)生改變時，太陽電池是不可能工作在當前情況下的**大功率點的。 </p> <p>

太陽能電池需要一個大面積的PN結以實現(xiàn)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。 </p><p> P型和N型都可以做電池片。 </p> <p> 在p型半導體材料上擴散磷元素，形成n+/p型結構的太陽電池即為P型硅片； </p> <p> 在N型半導體材料上注入硼元素，形成p+/n型結構的太陽電池即為n型硅片； </p> <p> 目前光伏行業(yè)主流產品是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，但是工藝更加復雜。N型硅片摻磷元素，磷與硅相溶性差，拉棒時磷分布不均，P型硅片摻硼元素，硼與硅分凝系數相當，分散均勻度容易控制。 </p> <p> 歡迎您的來電?。?！太陽能電池片的生產工藝?</p><div style="width:100%;text-align:

一般來說，單個的太陽能電池不能直接作為電源使用，在實際應用中，是將幾片或幾十片單個的太陽能電池串聯(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能連續(xù)供電的一種儲能裝置。當太陽光照射時，太陽能電池產生的電能不停地滿足當時的需要，而且還可多提供一些電能儲存于蓄電池內。 </p> <p> 太陽能電池首先是在空間飛行中得到應用的。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。當衛(wèi)星向著太陽飛行時，電池方陣受陽光照射產生電能，供應衛(wèi)生用電，同時向衛(wèi)星上的蓄電池充電；當衛(wèi)星背著太陽飛行時，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(完整片)各個規(guī)格面積？吉林雙晶太陽能電池片生產</p><p style="text-indent:25px">太陽能電池板能做的**小尺寸？吉林雙晶硅太陽能電池片廠家</p><p> 二、表面制絨 </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。吉林雙晶硅太陽能電池片廠家</p><p
