    • Combinatorial and machine learning approaches for the analysis of Cu2ZnGeSe4: influence of the off-stoichiometry on defect formation and solar cell performance 

      Grau Luque, Enric; Anefnaf, Ikram; Benhaddou, Nada; Fonoll Rubio, Robert; Becerril Romero, Ignacio; Aazou, Safae; Saucedo Silva, Edgardo Ademar; Sekkat, Zouheir; Pérez Rodríguez, Alejandro; Izquierdo Roca, Víctor; Guc, Maxim (Royal Society of Chemistry (RSC), 2021-04-28)
      Article
      Open Access
      Solar cells based on quaternary kesterite compounds like Cu2ZnGeSe4 are complex systems where the variation of one parameter can result in changes in the whole system, and, as consequence, in the global performance of the ...
    • Influence of amorphous silicon carbide intermediate layer in the back-contact structure of Cu2ZnSnSe4 solar cells 

      Colina Brito, Mónica Alejandra; Martín García, Isidro; Giraldo, Sergio; Sánchez González, Yudania; Kondrotas, Rokas; Oliva, Florian; Izquierdo Roca, Víctor; Pérez Rodríguez, Alejandro; Coll Valentí, Arnau; Alcubilla González, Ramón; Saucedo Silva, Edgardo Ademar (2016-08-01)
      Article
      Open Access
      Cu2 ZnSn(S1-ySey )4 (CZTS) thin-film solar cells have been qualified as potential competitors of the more established CIGS ones. One of the more important handicaps of CZTS solar cells is the open-circuit voltage deficit. ...
