The present invention relates to a multilayer coated substrate for reflecting the rear surface of a solar battery module and a manufacturing method therefor and, more specifically, to a multilayer coated substrate and a manufacturing method therefor, the multilayer coated substrate having a multilayer coating structure of being laminated on a transparent substrate, and having the following advantages when used as a substrate for reflecting the rear surface of a solar battery module (particularly, a glass-to-glass-type solar battery module): due to excellent mechanical strength, it is possible to prevent a reflective layer from being damaged by scratch or external shock; due to excellent durability, it is possible to keep the reflectivity of solar light excellent even in harsh environments such as a high-temperature desert area, and thus it is possible to ensure the lifespan of the solar battery module; due to exhibition of an insulating function, it is possible to solve the problem of the output of a module being reduced as a result of an increase in a leakage current of the solar battery module; and it is possible to improve the electricity generation output of a solar battery cell. |
