Title:
CONTROLLED EXPANSION FLEXIBLE METAL SUBSTRATE MATERIAL HAVING A TEXTURED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/073778
Kind Code:
A1
Abstract:
The present invention relates to a controlled expansion flexible metal substrate material and to a production method therefor. In the present invention, an electrocasting method is used in order to produce a metal substrate material which comprises a controlled expansion alloy and has a textured structure and a wide width. Also, the flexible metal substrate material of the present invention can be used as the substrate for a silicon thin-film solar cell since the Fe-Ni alloying compositional ratio is controlled in such a way that the thermal expansion coefficient approximates that of silicon. The present invention is devised in such a way that the optical pathway is extended and the photoelectric conversion efficiency is improved since a textured structure is provided on the surface of a flexible metal substrate material by forming a textured structure on the surface of a plating drum used as a plating cathode or anode used in an electrocasting method.
