Water and dust particles can lead to corrosion and pitting, posing a threat to photovoltaic cells. The backsheet’s role is to shield against moisture-related damage, including corrosion of electrical connections, insulation degradation, and the risk of short circuits.
Backsheets are the outermost “layer” for a solar panel, the first line of defense for solar cells. They play a critical role in protecting solar panels from harsh, varying environmental conditions over panel lifetimes. Not all backsheets are created equal.
UV rays can cause semiconductor materials within the solar cells to degrade, diminishing their performance and efficiency. The backsheet acts as a shield, protecting the cells from UV radiation. It’s important to note that over time, all backsheets will undergo a color change due to UV exposure.
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.
