電致發光el測試儀 我有新說法
211 0

電致發光（EL）測試儀是一種用于檢測太陽能電池板中電致發光現象的儀器。EL測試儀通過在光伏電池板中施加電壓，以激發電荷并產生光致發光現象。這樣可以幫助檢測和分析電池板內部的缺陷、裂紋、短路等問題，并評估其性能和質量。便攜式EL檢測儀根據不同的配置，深受好評的型號有山東競道光電科技有限公司生產的便攜式EL檢測儀【JD-EL1】、【JD-EL2】、【JD-EL3】以及無人機EL檢測儀【JD-EL4】等。

　　一、產品簡介

　　電致發光（EL）測試儀是一種用于檢測太陽能電池板中電致發光現象的儀器。EL測試儀通過在光伏電池板中施加電壓，以激發電荷并產生光致發光現象。這樣可以幫助檢測和分析電池板內部的缺陷、裂紋、短路等問題，并評估其性能和質量。便攜式EL檢測儀根據不同的配置，深受好評的型號有山東競道光電科技有限公司生產的便攜式EL檢測儀【JD-EL1】、【JD-EL2】、【JD-EL3】以及無人機EL檢測儀【JD-EL4】等。

　　二、工作原理

　　EL測試儀常用的工作原理是通過將電池板置于真空室內或在低溫環境下進行測試，然后施加電壓并使用高靈敏度的攝像機或光電二管（PD）來捕捉電池板的亮度圖像。這些圖像可以揭示出電池板中的問題，如火花、熱斑、電流分布等。

　　三、EL測試儀的一些主要特點和功能包括：

　　高分辨率圖像捕捉：EL測試儀通常具備高分辨率的相機或PD，能夠捕捉到細微的光致發光現象，并生成清晰的圖片。

　　多波長測試：一些EL測試儀允許在不同波長下進行測試，以便更全面地分析電池板。

　　自動化和快速測試：EL測試儀可以自動執行測試過程，從而提高效率。一些的儀器甚至可以在數分鐘內完成對整個電池板的測試。

　　缺陷識別和分析：EL測試儀可以幫助檢測并識別電池板中的各種缺陷，如裂紋、局部發光和短路等，并提供分析工具來評估其對性能的影響。

　　數據存儲和分析：EL測試儀通常具備數據存儲和導出功能，以便進行后續分析和比較，以提供更全面的評估和報告。

　　四、采購建議

　　EL測試儀的價格取決于型號、品牌和功能等因素。一般而言，其價格范圍從幾千美元到幾十萬美元不等。具體的價格請咨詢設備供應商或制造商以獲取準確的報價和詳細信息。
