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 electrolyte-containing polymer fibers having nano-wide diameters produced by an electrospin process, and to high efficiency dye-sensitized solar cells using same. The polymer fibers having nano-wide diameters, used as a solid-state electrolyte according to the present invention, may eliminate the necessity of a sealant and simplify processes as compared to dye-sensitized solar cells using conventional liquid-state electrolytes, and in particular significantly improves the energy converting efficiency of devices as compared to dye-sensitized solar cells using film-state polymer electrolytes produced by conventional spin coating processes. Further, high efficiency dye-sensitized solar cells can be produced from the electrolyte of the present invention by supplementing a scattering layer and the effect of interface.
