      Article
      Open Access
      Transition metal oxides (TMOs) are promising materials to develop selective contacts on high-efficiency crystalline silicon solar cells. Nevertheless, the standard deposition technique used for TMOs is thermal evaporation, ...
    • Contactos selectivos de portadores basados en óxidos metálicos de transición para células solares de kesterita 

      Almache Hernández, Rosa Estefanía (Universitat Politècnica de Catalunya, 2023-06-29)
      Doctoral thesis
      Open Access
      (English) In recent years, there has been an increasing need to find an environmentally friendly and low-pollution alternative for electricity production through solar energy absorption. Since 1950, photovoltaic researchers ...
