Abstract:
1. A dye-sensitized solar cell fabricating kit for fabricating a dye-sensitized solar cell, comprising: a semiconductor electrode having a semiconductor layer carrying a dye; an opposite electrode for bonding with the semiconductor electrode to form a liquid retention region between the semiconductor electrode and the opposite electrode, the opposite electrode and semiconductor electrode being configured to form the liquid retention region in such a manner to allow for an inlet through which an electrolytic solution can be supplied to the liquid retention region; a sealing member detachably attachable to the inlet, and configured for the closing of the inlet; a supply of initial electrolytic solution comprising an electrolyte dissolved in a solvent at a first electrolyte concentration and designed to be supplied between the semiconductor electrode and the opposite electrode during an initial assembly of a solar cell, and a supply of supplementary electrolytic solution provided independent of the supply of initial electrolytic solution, and designed to be supplied as a replenishment after the initial electrolytic solution is reduced in amount, the supplementary electrolytic solution comprising an electrolyte dissolved in a solvent at a second electrolyte concentration that is less than the first electrolyte concentration, wherein the second electrolyte concentration is a concentration amount designed to be supplied to a solar cell formed with the initial electrolyte solution, after a preset period of time during which the initial electrolyte solution has undergone volatilization, the second electrolyte concentration being effective to return the solar cell to at least 90% energy conversion efficiency relative to the energy conversion efficiency of the solar cell prior to the preset period of time, wherein the second electrolyte concentration (Y) and the first electrolyte concentration (C) satisfy the relationship (0.2C≦Y≦0.6C).
