The present invention relates to a glass material for sealing a large-area dye-sensitized solar cell and, more specifically, to a glass material which does not react with an electrolyte and allows uniform and high-strength binding even on a large area. According to the present invention, the glass material is expected to produce action effects of improving reliability and lifetime of solar cell products since it can uniformly seal a dye-sensitized solar cell, is chemically stable due to the absence of the reaction with an electrolyte, and has physical strength appropriate for large-area binding.
