Learn MoreBack-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.
Critical requirements for backsheet include UV resistance, damp heat resistance, high bond strength to the module encapsulant, inter-layer adhesion strength, dielectric breakdown, adequate moisture and oxygen barrier, and constructed to meet the minimum relative thermal index (RTI) values based on the safety requirements of the PV module.
Photovoltaic backsheets serve as environmental barriers in solar modules, protecting key electrical components from moisture and other ingress.
What is a backsheet? The backsheet is the outermost layer of the PV module and is designed to protect the inner components of the photovoltaic cells, electrical system, and to serve as an electrical insulator. Its functions as a weather barrier and seal off the components from rain, moisture, or other environmental conditions.
On the back side of a PV module backsheet films are used. Backsheets are multilayer laminates made from various polymeric materials and inorganic modifiers. The multilayer structure allows tailoring the optical, thermo mechanical, electrical and barrier properties of backsheets according to specific requirements for PV modules.
In addition to excellent long term performance encapsulation materials for photovoltaic (PV) modules should be cost efficient and easy to process. Modern PV modules as shown in Fig. 1 are sandwich type structures. The PV cell is often embedded in chemically crosslinked ethylene vinylacetate copolymer (EVA) .
