Abstract: A backsheet or frontsheet having an outer layer with a melting temperature greater than or equal to 150° C. includes at least one surface comprising a surface modification to improve adhesion between the backsheet or frontsheet and an encapsulant. The adhesion of the backsheet or frontsheet and encapsulant, after lamination, is at least 20 N/cm, preferably at least 40 N/cm or no adhesion failure. More preferably, the adhesion is at least 20 N/cm, even more preferably 40 N/cm or no adhesion failure, before and after 1,000 hours, preferably 2,000 hours, of damp heat aging at 85° C. and 85% humidity.
