Abstract:
There is provided a silver-coated copper powder which can improve the conversion efficiency of a solar cell in comparison with conventional silver-coated copper powders when it is used in an electrically conductive paste used for forming the busbar electrodes of the solar cell, the silver-coated copper powder being capable of producing a solar cell having a high conversion efficiency which is the same degree as that of a solar cell using silver powder, and a method for producing the same. A silver-coated copper powder obtained by coating the surface of a copper powder, which is obtained by the atomizing method or the like, with 5 wt % or more (with respect to the silver-coated copper powder) of a silver containing layer of silver or a silver compound, is added to a cyanide solution, such as a potassium silver cyanide solution, a potassium gold cyanide solution, a potassium cyanide solution or a sodium cyanide solution, to cause the copper powder coated with the silver containing layer to contain 3 to 3000 ppm of cyanogen.

Claim (Index 1):
A method for producing a silver-coated copper powder, the method comprising the steps of:\n preparing a copper powder, the surface of which is coated with a silver containing layer; and adding the copper powder to a cyanide solution to cause the copper powder coated with the silver containing layer to contain 3 to 3000 ppm of cyanogen.
