  • Patent number: 8828787
    Abstract: Processes for making a thin film solar cell on a substrate by providing a substrate coated with an electrical contact layer, depositing an ink onto the contact layer of the substrate, wherein the ink contains an alkali ion source compound suspended or dissolved in a carrier along with photovoltaic absorber precursor compounds, and heating the substrate. The alkali ion source compound can be MalkMB(ER)4 or Malk(ER). The processes can be used for CIS or CIGS.
