The present invention relates to a dye-sensitized solar cell module and to a production method therefor, and more specifically relates to a production method for a dye-sensitized solar cell module comprising an electrolyte, the method comprising a step of coating a water-repelling liquid onto the inside of an electrolyte injection port or a partition wall. According to the present invention, there is a reduction in the inter-substrate adhesive force due to the electrolyte, or the electrolyte is prevented from leaking, and thus the substrate can be reliably sealed.
