Abstract: An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet is disclosed. The backsheet may comprise a polymeric material that is produced in such a way that multiple functionalities are imparted into the material for outstanding performance and endurance in a solar module. The invention is further directed to a method for producing backsheets comprising such polymeric materials, and a solar cell incorporating such a backsheet. The backsheet may comprise a mono layer or multilayers in various embodiments. The backsheets improve upon the efficiency, strength, weather resistance, cost, and useful life of the solar panels in which the backsheets are incorporated.
