NOVELTY - Sealant (130) disposed between two substrates, comprises at least two layers disposed layered on top of each other between the two substrates, where at least two layers comprise material having different components and at least one of the at least two layer comprises a thermoplastic glass frit.    USE - The sealant is useful in dye-sensitized solar cell (claimed).    ADVANTAGE - The sealant: exhibits a high sealing quality and has uniform thickness, compared to the case where a single sealant layer has a laser sealing operation performed on it; prevents an electrolyte component from diffusing or transmitted and is discharged externally, compared to the case where a single sealant layer is formed of an organic-based resin material; and reduces the thermal damage of the dye and increases the durability against external shock since the organic-based sealing material has higher elasticity than an inorganic-based sealing material.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a dye-sensitized solar cell comprising: a first substrate (110) and a second substrate (100) disposed to face each other; a first electrode (210) and a second electrode (200) formed on the inner surfaces of the first and the second substrate, respectively; an electrolyte solution filled between the first and the second substrate; and a sealant disposed on the periphery of inner surfaces of the first and the second substrate to seal the electrolyte solution, and comprises a first and a second sealing layer, which are contacting the inner surface of the first and second substrate, respectively, and first electrode comprises a semiconductor oxide layer onto which many dye molecules are adsorbed, where at least one of the first sealing layer or the second sealing layer comprise a thermoplastic glass frit, and the first and second sealing layer comprises materials having different components; and    (2) manufacturing a dye-sensitized solar cell, comprising: forming a first and second electrodes on a first and second substrate, respectively; forming a first sealing layer on an inner surface of the first substrate or the second substrate; forming a second sealing layer on an inner surface of the first sealing layer or on a region of the second substrate corresponding to the first sealing layer; aligning and sealing the first and the second substrate; and injecting an electrolyte solution between the first and the second substrate, where the first and the second sealing layers comprise materials having different components, and at least the first sealing layer comprises a thermoplastic glass frit.
