The present invention provides a protective backing sheet for photovoltaic modules. The backing sheets of the current invention possess excellent weather resistance, heat resistance, color retention, adhesion between layers and encapsulant, and scratch resistance. The backing sheet can minimize the deterioration in the performance of the solar module due to moisture permeation. It also can achieve desirable photoelectric conversion efficiency over a long period of time. Additionally the described backing sheet, or alternately referred to backskin, can be made in an aesthetically pleasing form. |
