    • openAccess   Ionic Reactivity at Contacts and Aging of Methylammonium Lead Triiodide Perovskite Solar Cells 

      Carrillo, Jordi; Guerrero, Antonio; Rahimnejad, Sara; Almora Rodríguez, Osbel; Zarazúa, Isaac; Mas, Elena; Bisquert, Juan; Garcia-Belmonte, Germà Wiley (2016-02)
      Hybrid lead halide perovskites have reached very large solar to electricity power conversion efficiencies, in some cases exceeding 20%. The most extensively used perovskite-based solar cell configuration comprises CH3NH3PbI3 ...

    • 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 ...
