SINTERED OXIDE MATERIAL, METHOD FOR MANUFACTURING SAME, SPUTTERING TARGET, OXIDE TRANSPARENT ELECTRICALLY CONDUCTIVE FILM, METHOD FOR MANUFACTURING SAME, AND SOLAR CELL

摘要

The present invention provides an oxide sintered material (2) constituted from a crystal phase of a bixbyite-type oxide phase and a perovskite-type oxide phase or a bixbyite-type oxide crystal phase. The crystal phase has indium, tin, and strontium for constituent elements, and the atomic ratio of the indium, tin, and strontium content satisfies formulas (1) and (2). Also provided is a sputtering target. Also provided are an oxide transparent electrically conductive film formed using the sputtering target and a solar cell. Sn/(In + Sn + Sr) = 0.01 - 0.11 (1) Sr/(In + Sn + Sr) = 0.0005 - 0.004 (2) [In formulas (1) and (2), In, Sn, and Sr indicate content (atomic percent) for indium, tin, and strontium, respectively.]
