Electrolyte-containing polymer nanofibers produced by an electrospin process, and high efficiency dye-sensitized solar cells using same

摘要

The present invention relates to polymer electrolyte including a polymer fiber having a nanoscale diameter, wherein the polymer fiber is fabricated by an electrospinning method. The present invention also relates to a solar cell device exhibiting high energy conversion efficiency using the same. The solid-state electrolyte comprising nanosized polymer fiber of the present invention does not need a sealing agent and further simplifies the entire process compared to the conventional dye-sensitized solar cell using liquid electrolytes. Specifically, the energy conversion efficiency of the dye-sensitized solar cell of the present invention is significantly superior to that of the dye-sensitized solar cell using a polymer film electrolyte fabricated by a spin coating method. Further, the dye-sensitized solar cell devices can be obtained by using a scattering layer and compensating the surface effect.
