LIFETIME EXTENSION METHOD AND APPARATUS FOR DYE-SENSITIZED SOLAR CELL

摘要

The present invention relates to a method and apparatus for extending lifetime of dye-sensitized solar cell. Specifically, the present invention relates to a method for extending lifetime of dye-sensitized solar cell which comprises a negative electrode comprising semiconductor particles, a positive electrode facing the negative electrode, dye absorbed into the negative electrode, an electrolyte filled between the negative electrode and the positive electrode, and a frame surrounding them, said method comprising the step of i) supplementing to the electrolyte an electrolyte or insufficient component of the electrolyte, or ii) exchanging the electrolyte; and an apparatus for conducting the lifetime extension method of dye-sensitized solar cell. According to the present invention, durable lifetime of dye-sensitized solar cell equal to or longer than that of silicon solar cell can be achieved, thus enabling long-term stabilization and practical use of a solar cell.
