Abstract
Provided are an oxide tablet for vapor deposition (oxide evaporation material), and a vapor-deposited thin film and a solar cell formed using the same. The tablet comprises a sintered body which contains indium oxide as a main component and cerium and which is subjected to no surface grinding after sintering, in which Comp/Comp=0.9 to 1.1, where the content of cerium in a surface layer to a depth of 5 μm from a surface of the sintered body is represented by a Ce/In atomic ratio (Comp), and an average value of the content of cerium in the entire sintered body is represented by a Ce/In atomic ratio (Comp).
