Introduction: In solar photovoltaic power generation systems, photovoltaic modules are one of the key components. The encapsulation film is an indispensable part of photovoltaic modules, located between the battery cells and glass, as well as between the backplate and aluminum frame, which protects the battery cells from external environmental erosion and improves the photovoltaic conversion efficiency of the modules. This article will delve into the types and characteristics of photovoltaic…
