    • Fabricación de un sensor solar en dos ejes para el satélite IntaMicroSat 

      Calle Martín, Eric (Universitat Politècnica de Catalunya, 2011-07-15)
      Master thesis (pre-Bologna period)
      Open Access
      English: he goal of this project is the fabrication of a two axis sun sensor for the attitude control of the IntaMicroSat satellite. This sensor should detect the position of the sun with high accuracy (±1 º) and at an ...
    • Fabrication of silicon oxide microneedles from macroporous silicon 

      Rodríguez Martínez, Ángel; Molinero, D; Valera Cano, Enrique Andrés; Todorov Trifonov, Trifon; Marsal, L F; Pallarès Marzal, Josep; Alcubilla González, Ramón (2005-04)
      Article
      Restricted access - publisher's policy
      This paper presents a novel technique for silicon dioxide (SiO2) microneedle fabrication. Microneedles are hollow microcapillaries with tip diameters in the range of micrometers. They can be used in the fabrication of ...
    • Heterojunction diodes and solar cells fabricated by sputtering of GaAs on single crystalline Si 

      Silvestre Bergés, Santiago; Boronat Moreiro, Alfredo (2015-04-23)
      Article
      Open Access
      This work reports fabrication details of heterojunction diodes and solar cells obtained by sputter deposition of amorphous GaAs on p-doped single crystalline Si. The effects of two additional process steps were investigated: ...
    • Pentacene thin-films obtained by thermal evaporation in high vacuum 

      Puigdollers i González, Joaquim; Voz Sánchez, Cristóbal; Orpella García, Alberto; Martín García, Isidro; Vetter, Michael; Alcubilla González, Ramón (2003-03)
      Article
      Restricted access - publisher's policy
      Pentacene thin-films were obtained by thermal evaporation in high vacuum of a pure (98%) commercially available source. All the samples were grown at room temperature (25 °C) and high deposition rates (>20 Å/s) on Corning ...
    • Photodiodes based on fullerene semiconductor 

      Voz Sánchez, Cristóbal; Puigdollers i González, Joaquim; Cheylan, Stephanie; Fonrodona, A; Stella, M; Andreu Batallé, Jordi; Alcubilla González, Ramón (2007-07)
      Article
      Restricted access - publisher's policy
      Fullerene thin films have been deposited by thermal evaporation on glass substrates at room temperature. A comprehensive optical characterization was performed, including low-level optical absorption measured by photothermal ...
    • Reliability Study in Solar Panels 

      Español Lifante, Albert (Universitat Politècnica de Catalunya, 2012)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Crystalline silicon Modules are formed by single silicon photovoltaic cells. Since each one of these cells individually contributes to the overall electric power of the panel, the failure of one of them directly affects ...
