LID vs PID: What''s degrading your solar panels?

LID typically varies between 1-3%. The degradation of cells by sunlight is highly dependent on the quality of the wafer manufactured and is the result of a defect known as "boron oxygen complex". This defect occurs owing to oxygen being trapped in the silicon as part of the "Czochralski process" during manufacture. Solar panel PID
