    • closedAccess   Band unpinning and photovoltaic model for P3HT:PCBM organic bulk heterojunctions under illumination 

      Bisquert, Juan; Garcia-Belmonte, Germà; Munar, Antoni; Sessolo, Michele; Soriano, Alejandra; Bolink, Henk J. Elsevier (2008)
      Capacitance analysis of P3HT:PCBM bulk heterojunction solar cells, in dark and under illumination, shows a linear Mott-Schottky characteristic at moderate reverse bias, indicating p-doping of the organic blend. The flatband ...

    • closedAccess   Determination of charge carrier mobility of hole transporting polytriarylamine-based diodes 

      Barea, Eva M; Garcia-Belmonte, Germà; Sommer, Michael; Hüttner, Sven; Bolink, Henk J.; Thelakkat, Mukundan Elsevier (2010)
      Hole transport properties of three different side chain poly(triarylamines) have been determined by means of the analysis of steady-state current-voltage characteristics using co-planar diode structures. The interpretation ...

    • closedAccess   Efficient blue emitting organic light emitting diodes based on fluorescent solution processable cyclic phosphazenes 

      Bolink, Henk J.; Barea, Eva M; Costa, Rubén D; Coronado, Eugenio; Sudhakar, S Marla; Zhen, Changgua; Sellinger, Alan Elsevier (2008)
      Solution processable blue fluorescent dendrimers based on cyclic phosphazene (CP) cores incorporating amino-pyrene moieties have been prepared and used as emissive layers in organic light emitting diodes (OLEDs). These ...

    • openAccess   Inverted Solution Processable OLEDs Using a Metal Oxide as an Electron Injection Contact 

      Barea, Eva M; Bolink, Henk J.; Coronado, Eugenio; Repetto, Diego; Sessolo, Michele; Bisquert, Juan; Garcia-Belmonte, Germà; Procházka, Jan; Kavan, Ladislav Wiley-Blackwell (2008)
      A new type of bottom-emission electroluminescent device is described in which a metal oxide is used as the electron-injecting contact. The preparation of such a device is simple. It consists of the deposition of a thin ...

    • closedAccess   Operating modes of sandwiched light-emitting electrochemical cells 

      Lenes, Martijn; Garcia-Belmonte, Germà; Tordera, Daniel; Pertegás, Antonio; Bisquert, Juan; Bolink, Henk J. Wiley (2011-03-14)
      Light-emitting electrochemical cells (LECs) are promising lighting devices in which the redistribution of ionic charges allows for double electronic carrier injection from air-stable electrodes. Uncertainties about the ...

    • closedAccess   Perimeter leakage current in polymer light emitting diodes 

      Garcia-Belmonte, Germà; Montero Martín, José María; Ayyad Limonge Yassid; Barea, Eva M; Bisquert, Juan; Bolink, Henk J. Elsevier (2009)
      Observation of leakage current paths through the device perimeter in standard poly(phenylene vinylene)-based light-emitting devices is reported. Perimeter leakage currents govern the diode performance in reverse and low ...

    • closedAccess   Polymorphism-Triggered Reversible Thermochromic Fluorescence of a simple 1,8-Naphthyridine 

      Fernández Mato, Antonio; García, Marcos D.; Peinador, Carlos; Quintela, José M.; Sánchez Andújar, Manuel; Pato Doldán, Breogán; Señarís-Rodríguez, M. A.; Tordera, Daniel; Bolink, Henk J. ACS Publications (2013-01-04)
      The fluorescent behavior in the solid state of a naphthyridine-based donor–acceptor heterocycle is presented. Synthesized as a crystalline blue-emissive solid (Pbca), the compound can easily be transformed in its P21/c ...
