Lightweight Backsheets
The PV backsheets, one of the major components of solar panels, are designed to protect the internal photovoltaic cells and electrical components from moisture, temperature, UV, physical stress, as well electrical discharge. Responding to the increased demand for lighter weight panels, the mainstream backsheets nowadays consist of laminated resin films. The coating machines at Yasui Seiki are capable of depositing a few micron thin layers of adhesives onto substrate films (such as PET films) and then laminate with another film (such as olefin films) to create the lightweight backsheets.
