雙面電池問題：
將電池的后側(cè)改為光蓋，被發(fā)現(xiàn)使雙面PERC電池和模塊對后側(cè)的新型PID敏感，即去極化型PID(PID-p)和腐蝕型PID機制(PID-c)。
解決方案：
為了測試電池的這些類型的PID，我們開發(fā)了PIDcon雙面體。它是用溫度、照明和高電壓對完整的電池進行壓力測試，它可以在兩個方向上進行極化。通過測量照明下的IV曲線，可以確定PID的靈敏度。
應(yīng)用：
太陽能電池片PID檢測
HIT、Topcon 、PERC、AL-BSF、PERC+、雙面PERC、PERT、PERL和IBC太陽能電池的研究、生產(chǎn)和質(zhì)量控制。
