EL缺陷檢測儀是一種用于檢測電池片或光伏組件EL圖像中缺陷的設備。它通過注入電流產生電致發光，拍攝這些電致發光圖像，并使用算法分析EL圖像中的缺陷。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、產品優勢
EL缺陷檢測儀是一種用于檢測電池片或光伏組件EL圖像中缺陷的設備。它通過注入電流產生電致發光，拍攝這些電致發光圖像，并使用算法分析EL圖像中的缺陷。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、檢測類型
EL缺陷檢測儀可以幫助檢測太陽能電池片或光伏組件中的各種類型缺陷，如：
粉化或裂紋
暗斑點
灰塵或污染
電池片損壞或斷裂
三、重要作用
EL缺陷檢測儀可以提高電池片或光伏組件的生產效率和質量，有助于檢測生產線上的質量問題，并預測組件在使用中可能出現的問題。
除了使用EL缺陷檢測儀進行檢測外，還應注意其他一些檢測方法，如熱成像檢測來確定組件的熱點，來補充EL圖像不足之處。這些綜合工具的使用可以確保組件的質量和檢測出所有可能存在的缺陷，可以大限度地提高系統的生產效率和可靠性。
