  • Patent number: 9842705
    Abstract: A flexible dye-sensitized solar cell includes: a fiber layer formed of nanofibers; a conductive electrode layer formed on one side of the fiber layer; a photoelectrode layer formed on the conductive electrode layer; a counter electrode layer formed on the other side of the fiber layer; a sealing member for enclosing the fiber layer, the conductive electrode layer, the counter electrode layer and the photoelectrode layer therein so as to seal said layers from the outside; and an electrolyte infiltrated into the fiber layer. A cell body in which an electrode and a photoelectrode are formed on one surface of the fiber that contains an electrolyte therein and a counter electrode is formed on the other side of the fiber is sealed with a polymer film, thus forming a flexible solar cell having an excellent sealing structure for preventing the electrolyte from leaking out of the cell even when pressure is externally applied.
