The present invention relates to a multi-layer coating substrate for the reflection on the backside of a solar battery module, and a method for producing the same. More specifically, a reflection layer and an insulating protection layer stacked in order on a transparent substrate, and a solar battery module, especially a glass-to-glass type solar battery module, is used as a reflection material on the backside of the solar battery module for excellent mechanical strength thereof and for preventing scratches or other external impacts to the reflection layer. Since the multi-layer coating substrate possess an excellent durability, solar reflection rates even in harsh conditions such as hot desserts can be maintained at an outstanding state, thereby guaranteeing the durability of the solar battery module, at the same time insulating the module to prevent a decline in the output of the module due to a leakage current. The multi-layer coating substrate comprises a transparent substrate; a reflection metal layer; and an insulation protective layer. |
