摘要:
A dye-sensitized solar cell including a polymer electrolyte gel having a poly(vinylidene fluoride) (PVDF) polymer is provided. The dye-sensitized solar cell includes a semiconductor electrode, an opposed electrode, and a polymer electrolyte gel interposed between the semiconductor electrode and the opposed electrode while including poly(vinylidene fluoride) (PVDF) polymer or the copolymer thereof. Here, the polymer electrolyte gel is formed of a N-methy-2-pyrrolidone solvent or a 3-methoxypropionitrile (MP) solvent and the PVDF polymer or the copolymer thereof which is dissolved in the solvent to a predetermined amount.

There is provided a system for cleaning a surface of a solar cell panel. The system includes a measurement unit measuring a power generation value of a solar cell panel, a reference unit providing a reference value, a control unit comparing the power generation value measured at the measurement unit with the reference value provided from the reference unit to command cleaning of the solar cell panel, a driving unit operating a cleaning apparatus for cleaning a surface of the solar cell panel. The control unit commands cleaning of the solar cell panel only when the power generation value decreases because of a contamination of the surface of the solar cell panel.
