    N-type organic thin film transistor (OTFT) with a top-contact structure was fabricated by thermal vapour deposition using N,N'-Dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) as an n-channel layer on Si/SiO2 substrate. ...
  • A Second-Order Delta-Sigma Control of Dielectric Charge for Contactless Capacitive MEMS 

    Gorreta Mariné, Sergio; Pons Nin, Joan; Blokhina, Elena; Domínguez Pumar, Manuel (2015-04-01)
    Article
    Open Access
    This letter introduces a new second-order delta-sigma method for controlling the dielectric charge in contactless capacitive microelectromechanical systems. This method improves the one previously proposed by the authors, ...

    Electrowetting on Dielectric (EWOD) has been studied for more than a decade and used for different applications but still there are few works on non-aqueous liquids such as mixtures of polyols. We have found that significant ...
  • 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: ...

    In crystalline silicon (c-Si) solar cell field, an intensive effort is being paid to reduce the quantity of silicon material used in each cell in order to minimize its costs. With the reduction of wafer thickness, light ...
  • Real-time characterization of dielectric charging in contactless capacitive MEMS 

    Domínguez Pumar, Manuel; Gorreta Mariné, Sergio; Pons Nin, Joan; Blokhina, Elena; Giounanlis, Panonios; Feely, Orla (2015-03-01)
    Article

    This paper presents a new method to characterize the dynamics of the charge trapped in the dielectric layer of contactless microelectromechanical systems. For sampled-time systems, this allows knowing the state of the net ...
  • Three-dimensional metallo-dielectric selective thermal emitters with high-temperature stability for thermophotovoltaic applications 

    Garin Escriva, Moises; Hernández García, David; Todorov Trifonov, Trifon; Alcubilla González, Ramón (2015-03-01)
    Article
    Restricted access - publisher's policy
    Selective thermal emitters concentrate most of their spontaneous emission in a spectral band much narrower than a blackbody. When used in a thermophovoltaic energy conversion system, they become key elements defining both ...
  • Artificial bee colony based algorithm for maximum power pointtracking (MPPT) for PV systems operating under partial shaded conditions 

    Benyoucef, Abou soufyane; Chouder, Aissa; Kara, Kamel; Silvestre Bergés, Santiago; Shaed, Oussama Ait (2015-07-01)
    Article
    Restricted access - publisher's policy
    Artificial bee colony (ABC) algorithm has several characteristics that make it more attractive than other bio-inspired methods. Particularly, it is simple, it uses fewer control parameters and its convergence is independent ...
  • Large Stokes shift downshifting Eu(III) films as efficiency enhancing UV blocking layers for dye sensitized solar cells 

    Kennedy, M.; Ahmed, H.; Doran, J.; Norton, B.; Daren, S.; Galindo Lorente, Sergi; Voz Sánchez, Cristóbal; Puigdollers i González, Joaquim (2015-01-01)
