Title:
METHOD FOR FABRICATING SOLAR CELL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/076886
Kind Code:
A3
Abstract:
A method for fabricating a solar cell element, the method comprising a step (a) of preparing a laminate and a chamber, a step (b) of bringing the laminate into contact with the aqueous solution in such a manner that the second surface is immersed in the aqueous solution after the step (a); a step (c) of applying a voltage difference between an anode electrode and the laminate under an atmosphere of the inert gas to form a Zn layer on the second surface after the step (b); and a step (d) of exposing the Zn layer to oxygen so as to convert the Zn layer into a ZnO crystalline layer after the step (c).
