Title:
SEMICONDUCTOR FILM, AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2012/035833
Kind Code:
A1
Abstract:
The present invention provides a semiconductor film in which both the band gap and the resistivity or carrier density are suitable for a solar cell. This semiconductor film comprises a semiconductor containing Group 11, 12, 13, and 16 elements in the ratio indicated by compositional formula (1): AxByCzDw (where A, B, C, and D each represent a Group 11, 12, 13, and 16 element, respectively; x, y, z, and w are numbers representing compositional ratios; and x and z satisfy the relationship x/z > 1).
