WIPO Patent Application WO/2013/128797
Kind Code:
A1
Abstract:
Provided is a current collector capable of obtaining higher photoelectric conversion efficiency when being used for a dye-sensitized solar cell. A method for manufacturing current collector for dye-sensitized solar cell comprising a porous metal sheet comprises: a process of forming a sheet made from an alloy of a first metal component and a second metal component; a process of treating the sheet at a temperature lower than the minimum value of liquidus temperature in the phase diagram of the alloy by immersing the sheet in a molten metal bath of a third metal component which has positive heat of mixing for the first metal component and negative heat of mixing for the second metal component, while having a hardening point lower than the melting point of the alloy; and a process of taking the treated sheet from the molten metal bath. The current collector for dye-sensitized solar cell comprising porous metal sheet has a number of through-holes with nano-diameters isotropically communicating with each other with spherical molten metal lumps being mutually fused in three-dimensional directions.
