Why Your Solar Panels Fail Early (And How Advanced Encapsulation Stops It)
# Advanced Encapsulation Materials: The Critical Barrier Between Solar Cells and Environmental Degradation
Encapsulation materials serve as the primary defense system protecting photovoltaic cells from moisture ingress, UV radiation, thermal stress, and mechanical damage—factors that can reduce panel efficiency by up to 30% within the first decade of operation. These polymer-based layers, typically ethylene vinyl acetate (EVA) or emerging alternatives like polyolefin elastomers (POE) and thermoplastic polyurethane (TPU), must maintain optical transparency exceeding 90% while withstanding temperature fluctuations from -40°C to 85…
