  • V2Ox-based hole-selective contacts for c-Si interdigitated back-contacted solar cells 

    Masmitjà Rusiñol, Gerard; Gerling Sarabia, Luis Guillermo; Ortega Villasclaras, Pablo Rafael; Puigdollers i González, Joaquim; Martín García, Isidro; Voz Sánchez, Cristóbal; Alcubilla González, Ramón (Royal Society of Chemistry, 2017-05-21)
    Article
    Accés restringit per política de l'editorial
    Over the last few years, transition metal oxide layers have been proposed as selective contacts both for electrons and holes and successfully applied to silicon solar cells. However, better published results need the use ...
  • Recombination processes in passivated boron-implanted black silicon emitters 

    von Gastrow, Guillaume; Ortega Villasclaras, Pablo Rafael; Alcubilla González, Ramón; Husein, Sebastian; Nietzold, Tara; Bertoni, Mariana; Savin, Hele (American Institute of Physics (AIP), 2017-05-14)
    Article
    Accés restringit per política de l'editorial
    In this paper, we study the recombination mechanisms in ion-implanted black silicon (bSi) emitters and discuss their advantages over diffused emitters. In the case of diffusion, the large bSi surface area increases emitter ...
  • Statistical fault detection in photovoltaic systems 

    Garoudja, Elyes; Harrou, Fouzi; Sun, Ying; Kara, Kamel; Chouder, Aissa; Silvestre Bergés, Santiago (2017-07-01)
    Article
    Accés restringit per política de l'editorial
    Faults in photovoltaic (PV) systems, which can result in energy loss, system shutdown or even serious safety breaches, are often difficult to avoid. Fault detection in such systems is imperative to improve their reliability, ...
  • Influence of amorphous silicon carbide intermediate layer in the back-contact structure of Cu2ZnSnSe4 solar cells 

    Colina Brito, Mónica Alejandra; Martín García, Isidro; Giraldo, Sergio; Sánchez González, Yudania; Kondrotas, Rokas; Oliva, Florian; Izquierdo Roca, Víctor; Pérez Rodríguez, Alejandro; Coll Valentí, Arnau; Alcubilla González, Ramón; Saucedo Silva, Edgardo Ademar (2016-08-01)
    Article
    Accés obert
    Cu2 ZnSn(S1-ySey )4 (CZTS) thin-film solar cells have been qualified as potential competitors of the more established CIGS ones. One of the more important handicaps of CZTS solar cells is the open-circuit voltage deficit. ...
  • Superior performance of V2O5 as hole selective contact over other transition metal oxides in silicon heterojunction solar cells 

    Almora, Osbel; Gerling Sarabia, Luis Guillermo; Voz Sánchez, Cristóbal; Alcubilla González, Ramón; Puigdollers i González, Joaquim; Garcia-Belmonte, Germà (2017-08-01)
    Article
    Accés restringit per política de l'editorial
    Transition metal oxides (TMOs) have recently been proved to efficiently serve as hole-selective contacts in crystalline silicon (c-Si) heterojunction solar cells. In the present work, two TMO/c-Si heterojunctions are ...

    Article
    Accés obert
    This work investigates, analytically and experimentally, the effects induced by the use of a first-order sigma-delta (S¿) feedback loop as a control method of dielectric charging for capacitive microelectromechanical systems ...
  • Rapid room temperature crystallization of TiO2 nanotubes 

    Aijo, John K.; Thankamoniamma, Manju; Puigdollers i González, Joaquim (2017-02-20)
    Article
    Accés restringit per política de l'editorial
    The paper reports a very efficient and reproducible technique for room temperature crystallization of titanium dioxide in a record time of 5 minutes, by application of alternating voltage square pulses. The well aligned ...
  • Origin of passivation in hole-selective transition metal oxides for crystalline silicon heterojunction solar cells 

    Gerling Sarabia, Luis Guillermo; Voz Sánchez, Cristóbal; Alcubilla González, Ramón; Puigdollers i González, Joaquim (2017-01-23)
    Article
    Accés obert
    Transition metal oxides (TMOs) have recently demonstrated to be a good alternative to boron/phosphorous doped layers in crystalline silicon heterojunction solar cells. In this work, the interface between n-type c-Si (n-Si) ...
  • 3Cat-1 project: a multi-payload CubeSat for scientific experiments and technology demonstrators
