This page brings together solutions from recent research—including polyurethane hot-melt adhesive films, dual-layer encapsulation structures, polyaspartate polyurea barriers, and TPU-based flexible encapsulation systems. Learn how advanced materials prevent degradation, eliminate acid damage, and boost energy production throughout your system's lifetime. There are several ways to do encapsulation. This shield protects them from things like water, sunlight, and heat changes. Some panels still have almost 19. This protective layer acts as a barrier. . NREL is a national laboratory of the U.
