OXIDE SINTERED BODY, SPUTTERING TARGET USING THE SAME AND OXIDE FILM

摘要

PROBLEM TO BE SOLVED: To provide an oxide sintered body for a sputtering target to which a specific element can be added from an n-type semiconductor layer to a p-type semiconductor layer surface of a compound thin-film solar cell.SOLUTION: There is provided an oxide sintered body which contains zinc and at least one type of element (X) (provided that a case where magnesium only is added is excluded) which has an ionization potential (Ip) of 4.5 eV≤Ip≤8.0 eV and an atomic radius (d) of 1.20Å≤d≤2.50Å or less, and further has a composition ratio (atomic ratio) of 0.0001≤X/(Zn+X)≤0.20 and a sintered density of 95% or more.
