Abstract:
The present invention relates to screen-printable quaternary chalcogenide compositions. The present invention also provides a process for creating an essentially pure crystalline layer of the quaternary chalcogenide on a substrate. Such coated substrates contain p-type semiconductors and are useful as the absorber layer in a solar cell.
