A solar cell module according to the present invention includes at least one solar cell; a sealing material stacked to surround the upper surface and the lower surface of the solar cell; a transparent insulating substrate stacked on the upper surface of the sealing material; and a back sheet stacked on the lower surface of the sealing material. The sealing material is made of a LDPE group material. The back sheet is formed by successively arranging a PE layer, a PET layer, and a PVDF layer on the lower surface of the sealing material, thereby preventing a yellowing phenomenon and corrosion phenomenon caused by moisture penetration, improving productivity by reducing melting hours required for bonding the materials of a stacked module, improving the junction of the back sheet to the sealing material made of LDPE, preventing the generation of surface curve, and improving structural stability. |
