    • Etching techniques for thinning silicon wafers for ultra thin high efficiency IBC solar cells 

      Afa, Iduabo John (Universitat Politècnica de Catalunya, 2014-09-08)
      Master thesis
      Open Access
      [ANGLÈS] High efficiency Interdigitated back contact (IBC) solar cells help reduce the area of solar panels needed to supply sufficient amount of energy for household consumption. We believe that a properly passivated IBC ...
    • Paper-based microfluidic sensing devices fabricated by inkjet printing technology 

      Guirao Expósito, Bernat (Universitat Politècnica de Catalunya / Keio University, 2010)
      Master thesis (pre-Bologna period)
      Open Access
      The detection of some analytes, for example heavy metal ions, is crucial in locations such as developing countries or humanitarian emergencies, where no qualified professionals or sophisticated equipment is available. In ...
    • Sensing of particles, micro-organisms and biomarkers using the camera of a mobile phone 

      Cazaban, Mélanie (Universitat Politècnica de Catalunya, 2017-09-05)
      Master thesis
      Open Access
      Covenantee:   Université Toulouse III - Paul Sabatier
      We demonstrate a simple method to shape an incoherent light source in periodic patterns of the type of cos2n(kxx)cos2m(kyy) by using pairs of birrefringent crystals known as Savart Plates. These patterns scalable and show ...
    • Silicon micromachined lens antenna for THz integrated heterodyne arrays 

      Llombart Juan, Nuria; Lee, Choonsup; Alonso del Pino, María; Chattopadhyay, Goutam; Jung Kubiak, Cecile; Jofre Roca, Lluís; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
      Restricted access - publisher's policy
      In this paper, we present the design, fabrication, and measurements of a lens THz antenna that can be fabricated using conventional photolithography and deep reactive etching processes. The antenna is composed of an extended ...
    • Silicon Nanopillar Solar Cells Made by Near Field Phase-Shift Photolithography 

      Canales Mundet, Ignasi (Universitat Politècnica de Catalunya, 2012)
      Master thesis (pre-Bologna period)
      Open Access
      A novel photolithographic technique which promises quick and easy large area patterning is explored to satisfy the nanowire applications requirements. Nanohole patterns for ordered nanowire growth and nanopillar arrays ...
