Unraveling the Impact of Combined NaF/RbF Postdeposition Treatments on the Deeply Buried Cu(In,Ga)Se2/Mo Thin‐Film Solar Cell Interface

Unraveling the Impact of Combined NaF/RbF Postdeposition Treatments on the Deeply Buried Cu(In,Ga)Se2/Mo Thin‐Film Solar Cell Interface

Cu(In,Ga)Se2 (CIGSe) is a promising absorber material for thin‐film photovoltaic devices. A key procedure to achieve high efficiencies is the application of alkali fluoride postdeposition treatments (PDT) of the CIGSe surface. While the effects of the PDT on the directly impacted CIGSe front surface...
