Abstract
The present invention provides an intermediate structure for use in manufacturing a dye-sensitized solar cell (DSSC) and a method for manufacturing a DSSC with the intermediate structure. The intermediate structure comprises a first electrode coated with a nano-particle oxide and a second electrode laminated with the first electrode by a layer formed of a sealant. The sealant layer has openings in predetermined positions such that at least a portion of the internal space formed by the first electrode, the second electrode, and the sealant layer can communicate with the outside. With the intermediate structure, a superior quality of a DSSC can be manufactured in a simpler and more cost-effective way.
