A polymer electrolyte including a polymer fiber having a nanoscale diameter, wherein the polymer fiber is fabricated by an electrospinning method and a solar cell device exhibiting high energy conversion efficiency using the same. The solid-state electrolyte comprising such nanosized polymer fiber does not need a sealing agent and further simplifies the entire process compared to a conventional dye-sensitized solar cell using liquid electrolytes. Specifically, the energy conversion efficiency of the present dye-sensitized solar cell is significantly superior to that of a dye-sensitized solar cell using a polymer film electrolyte fabricated by a spin coating method. Further, the present dye-sensitized solar cell device can be obtained by using a scattering layer and compensating the surface effect.
摘要:
A method of forming a nanometer-scale prominence and depression structure on a zinc oxide thin film in a wet-etching method, and the method includes the steps of: preparing a substrate; forming a nano structure having a height and a width of a nanometer range; forming the zinc oxide thin film on the substrate on which the nano structure is formed; and wet-etching the zinc oxide thin film, in which in the wet-etching step, zinc oxide having relatively low physical compactness is preferentially etched since the zinc oxide is positioned on the nano structure, and thus the prominence and depression structure is formed around the nano structure by the etching.The method is effective in that a thin film can be uniformly formed on the prominence and depression structure, and an electrolyte or an organic material may uniformly penetrate between the prominence and depression structure.
