Abstract:
PROBLEM TO BE SOLVED: To provide a magnesium mother alloy with improved oxidation and ignition properties and a production method thereof; to provide a metal alloy with low cost that is suitable for design purposes using the magnesium mother alloy; and to provide a production method of the metal alloy.SOLUTION: The magnesium mother alloy includes a plurality of magnesium crystal grains, and a scandium compound crystallized at grain boundaries which are not inside but outside the magnesium crystal grains. The metal alloy suitable for design purposes is produced inexpensively by adding the magnesium mother alloy containing scandium into a magnesium alloy or an aluminum alloy. The production method of the metal alloy is also provided.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a solar cell by utilizing an inductively coupled plasma enhanced chemical vapor deposition method. SOLUTION: In manufacturing a solar cell including: a first electrode; a first frame layer; an intrinsic layer; a second frame layer; and a second electrode, an inductively coupled plasma enhanced chemical vapor deposition device using a mixed gas containing a hydrogen (H 2 ) gas and a silane (SiH 4 ) gas is used, and the manufacturing method includes an intrinsic layer forming step of forming the intrinsic layer consisting of a hydride amorphous silicon thin film, wherein the mixed gas has the ratio (H 2 /SiH 4 ) of the hydrogen gas and the silane gas to the hydrogen gas is 8-10.
