摘要:
Disclosed is a solid electrolyte for a dye-sensitized solar cell, which includes a three-dimensional porous thin film made of a hydrophilic polymer material, and a dye-sensitized solar cell using the same. More particularly, the present invention provides a high-efficient dye-sensitized solar cell, in which polymer nanofibers having high specific surface area are used in an electrolyte layer to effectively induce an increase in photocurrent, thereby increasing the amount of electrolyte impregnated. When the porous film prepared by the method of the present invention is used as a solid electrolyte for a dye-sensitized solar cell, a process of forming an electrolyte inlet and sealing the inlet is not required, which simplifies the entire process, compared to an existing dye-sensitized solar cell using a liquid electrolyte.

Disclosed is a conductive polymer which is easily dispersed in an organic solvent. A method of preparing the conductive polymer adapted to be dispersed in an organic solvent is also provided, which includes chemically polymerizing a monomer using as a dopant anion a phosphate-based compound having solubility in an organic solvent. The conductive polymer capable of being dispersed in various organic solvents can be obtained through a simple preparation process, and thus can be utilized in the fields of applied materials in which the use of conventional water-dispersible conductive polymers is limited.

A digital camera capable of variably setting a frame rate may include an imaging device which outputs a plurality of temporally continuous image frames when photographing a moving image. The digital camera may also include a digital signal processor that determines a frame rate with which the image frames are filed, wherein the digital signal processor variably determines the frame rate according to a motion speed of a subject in the frames. The digital camera may further include a recording medium in which the filed image frames are stored. Accordingly, as the frame rate is varied according to the motion of a subject, the motion of the subject can be smoothly realized in a high motion speed section from a reproduction perspective, and substantially repeated image frames can be removed in a low speed motion section. Thus, the size of moving image files can be reduced, saving memory resources.
