The present description is directed to a manufacturing method of solid-state dye-sensitized solar cells and a solid-state electrolyte filling device used in the manufacturing method. The present invention provides a manufacturing method of dye-sensitized solar cells that fills the solid-state electrolyte more uniformly with enhanced efficiency to secure higher light-to-energy conversion efficiency.

Manufacturing method of solid-state dye-sensitized solar cells and electrolyte filling device used therefor

The following description relates to a method of low temperature sintering a catalyst layer that formed on one side of a counter electrode using a laser. It is possible to prepare a counter electrode for a dye-sensitized solar cell (DSSC) based on a flexible substrate easily because the method can be applied to a conducting substrate made of plastic materials as well as a conducting glass substrate.

Method of preparing counter electrode for dye-sensitized solar cell

The present invention relates to a counter electrode for DSSC which includes a porous membrane include a carbon-based material calcinated at high temperature and a platinum nano-particles and maintains higher conductivity than a thin membrane and in which the electrolyte moves smoothly, a method of preparing the same, and a DSSC using the same which is improved in photoelectric efficiency.

Counter electrode for dye-sensitized solar cell and preparation method thereof

Nitrogen trifluoride is produced with a high yield by the method comprising forming a fast stream of micro droplets of a fused ammonium fluoride salt by rapidly ejecting the fused ammonium fluoride salt into a reactor through a nozzle while circulating the fused ammonium fluoride salt in the reactor from a lower portion to an upper portion; and contacting micro droplets of the fused ammonium fluoride salt with fluorine gas sucked in the reactor through a suction pipe for fluorine by a negative pressure formed around the nozzle due to an ejection of the fused ammonium fluoride salt, whereby excessive generation and regional accumulation of the heat of reaction are prevented, reducing the reaction temperature by 10&#x2dc;30&#xb0; C. compared with those of the existing methods, and a side reaction occurs only to a slight extent according to the lowered reaction temperature.

Method for producing nitrogen trifluoride using jet-loop reactors

The present invention relates to a refrigerant composition of four-constituent system, comprising: (a) a first constituent of difluoromethane, (b) a second constituent of 1,1,1,2,3,3,3-heptafluoropropane, (c) a third constituent selected from the group consisting of 1,1,1,2-tetrafluoroethane and 1,1-difluoroethane and (d) a for the constituent selected from the group consisting of isobutane, 1,1,1,2,3,3,-hexafluoropropane and butane, useful as a substitute for chlorodifluoromethane (HCFC-22).
