Electrical Performance & Temperature Dependence
What is the LID/LeTID phenomenon?
LID (Light Induced Degradation) and LeTID (Light and Elevated Temperature Induced Degradation) are two phenomena that affect the performance of solar cells. Especially in high-power output modules, these issues are particularly important. The following is an explanation of the LID and LeTID phenomena and their impact on 610-635 watt single-sided modules.
LID：LID refers to the performance degradation phenomenon that occurs when solar cells are exposed to sunlight for the first time. This phenomenon is mainly due to the formation of boron-oxygen complexes in the battery material (usually p-type monocrystalline silicon) under illumination, resulting in a reduction in the efficiency of the battery.
LeTID：LeTID is another performance degradation phenomenon. It occurs when the battery operates under high temperature (for example, above 70 °C) and illumination conditions. The performance degradation caused by LeTID is more serious than that of LID, and the recovery speed is slower.
