    • 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 ...
