Light-induced degradation, also known as LID, has a significant impact on solar silicon wafers. It causes a decrease in the efficiency and performance of the solar cells over time. LID occurs when the silicon material is exposed to light, particularly in the presence of boron or oxygen impurities. This exposure leads to the creation of defects and traps within the material, which results in a decrease in the solar cell's ability to generate electricity. Consequently, LID reduces the overall power output of the solar panel and requires additional measures to mitigate its effects, such as anti-LID coatings or improved cell designs.
