    • openAccess   Carrier recombination flux in bulk heterojunction polymer: fullerene solar cells: Effect of energy disorder on ideality factor 

      Garcia-Belmonte, Germà Elsevier (2013-01)
      Energy disorder reduces the achievable open-circuit voltage in organic bulk-heterojunction solar cells. Here the effect of disorder on charge carrier recombination flux is numerically modeled. The recombination current ...

    • openAccess   Diamond-based electrodes for organic photovoltaic devices 

      Kovalenko, Alexander; Ashcheulov, Petr; Guerrero, Antonio; Heinrichová, Patricie; Fekete, Ladislav; Vala, Martin; Weiter, Martin; Kratochvílová, Irena; Garcia-Belmonte, Germà Elsevier (2015-03)
      The present paper demonstrates the possibility of replacing indium–tin oxide (ITO) with heavily boron-doped diamond (BDD). Plasma Enhanced Chemically Vapor Deposited BDDs layers of various thicknesses were prepared containing ...

    • openAccess   Electrodeposited NiO anode interlayers: Enhancement of the charge carrier selectivity in organic solar cells 

      Ripollés Sanchis, Teresa; Guerrero, Antonio; Azaceta, Eneko; Tena-Zaera, Ramón; Garcia-Belmonte, Germà Elsevier (2013-10)
      Nickel oxide (NiO) thin films prepared by cathodic electrodeposition exhibit superior electrical performace than PEDOT:PSS when used as anode interlayers of bulk-heterojunction solar cells. Devices incorporating 30 nm-thick ...

    • openAccess   Nano-enabled photovoltaics. Progress in materials and methodologies 

      Bisquert, Juan American Chemical Society (2013)
      Nanoenabled photovoltaics consist of a family of related approaches to make solar cells that use nanosized material elements, involving a combination of inorganic and organic components and hard and soft matter, including ...

    • openAccess   Nanoscale mapping by electron energy-loss spectroscopy reveals evolution of organic solar cell contact selectivity 

      Guerrero, Antonio; Pfannmöller, Martin; Kovalenko, Alexander; Ripollés Sanchis, Teresa; Heidari, Hamed; Bals, Sara; Kaufmann, Louis-Dominique; Bisquert, Juan; Garcia-Belmonte, Germà Elsevier (2015)
      Organic photovoltaic (OPV) devices are on the verge of commercialization being long-term stability a key challenge. Morphology evolution during lifetime has been suggested to be one of the main pathways accounting for ...

    • openAccess   Oxygen doping-induced photogeneration loss in P3HT:PCBM solar cells 

      Garcia-Belmonte, Germà; Ripollés Sanchis, Teresa; Guerrero, Antonio; Boix, Pablo P; Marchesi, Luis F.; Pereira, Ernesto C. Elsevier (2012-05)
      This work investigates the loss in performance induced by molecular oxygen in bulk heterojunction solar cells. We observe that upon exposure to molecular oxygen both formation of P3HT+:O2− complex and metal oxidation at ...

    • openAccess   Role of Vertical Segregation in Semitransparent Organic Photovoltaics 

      Kovalenko, Alexander; Guerrero, Antonio; Garcia-Belmonte, Germà ACS Publications (2015)
      In this work, the efficiency of semitransparent organic photovoltaic (OPV) devices for low intensity applications is investigated as a function of the processing conditions. It is observed that a thermal treatment of the ...
