Light-Induced Degradation (LID) is a phenomenon that temporarily reduces the efficiency of solar cells in PV modules, primarily affecting boron-doped silicon solar cells. . LID is an acronym for Light-Induced Degradation. This degradation. . The term “LID” (Light Induced Degradation) is commonly used in solar panel installation literature and industry trade journals as a synonym for thermal shock. They lose power gradually, year after year, until they're no longer pulling their weight. That's the real story behind solar panel lifespan. Not just how long they last, but how well they perform along the way. Most silicon solar cells are affected by this defect, causing severe loss in power. . Solar panels, also known as photovoltaic (PV) modules, have transformed how we capture sun energy.
