BACK SHEET FOR SOLAR CELL

摘要

PURPOSE: A back sheet for a solar cell is provided to reduce manufacturing costs by simultaneously performing manufacturing processes with a T die extrusion method. CONSTITUTION: An outer layer (100) is made of modified PP. A middle layer (200) is directly bonded to the outer layer. An inner layer (300) is directly bonded to the middle layer. The opposite surface of the inner layer is made of the modified PP or a mixture. Each bonding surface of the outer layer and the inner layer is physically or chemically processed.
