Abstract: A solar cell module includes: a solar cell comprising a perovskite solar cell; a first encapsulating material and a second encapsulating material for sealing the solar cell; a first protective member positioned on the first encapsulating material; a second protective member positioned on the second encapsulating material; and a third encapsulating material positioned on a side surface of the first encapsulating material and the second encapsulating material. The water vapor transmission rate (WVTR) of the third encapsulating material is less than the WVTR of the second encapsulating material, and the WVTR of the second encapsulating material is less than the WVTR of the first encapsulating material. Thus, it is possible to obtain the effects of securing the conversion efficiency of the solar cell module against degradation and securing reliability of the solar cell module.
