Photovoltaic backsheets are a critical component of solar modules, providing essential electrical insulation and environmental protection. Recent research has highlighted that the degradation of these ...

A Qatari research group has analyzed the performance of polyethylene terephthalate backsheets in real outdoor testing conditions in desert areas and has identified the main causes that lead to ...

Hard-pressed Asian solar manufacturers have switched from multi-layer polymer backsheets to a single layer of polyethylene terephthalate (PET), with a protective coating on both sides of their modules ...

A typical three-layered structure of a backsheet is comprised of an outer layer with ideal properties to resist environmental stress, a middle layer for good electrical insulation, and an inner layer ...
