  • Alkali dispersion in (Ag,Cu)(In,Ga)Se2 thin film solar cells – Insight from theory and experiment 
    Aboulfadl, Hisham; Sopiha, Kostiantyn; Keller, J; Larsen, J; Scragg, Jonathan; Persson, Clas; Thuvander, Mattias; Edoff, Marika (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Silver alloying of Cu(In,Ga)Se2 absorbers for thin film photovoltaics offers improvements in open-circuit voltage, especially when combined with optimal alkali-treatments and certain Ga concentrations. The relationship ...
  • Dynamic Impurity Redistributions in Kesterite Absorbers 
    Grini, Sigbjørn; Aboulfadl, Hisham; Ross, Nils; Persson, Clas; Platzer-Björkman, Charlotte; Thuvander, Mattias; Vines, Lasse (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Cu2ZnSn(S,Se)4 is a promising nontoxic earth‐abundant solar cell absorber. To optimize the thin films for solar cell device performance, postdeposition treatments at temperatures below the crystallization temperature are ...
