    • openAccess   Analysis of the Hysteresis Behavior of Perovskite Solar Cells with Interfacial Fullerene Self-Assembled Monolayers 

      Vallés Pelarda, Marta; Clasen Hames, Bruno; García-Benito, Inés; Almora Rodríguez, Osbel; Molina-Ontoria, Agustín; S. Sánchez, Rafael; Garcia-Belmonte, Germà; Martín, Nazario; Mora-Sero, Ivan American Chemical Society (2016-10)
      The use of self-assembled monolayers (SAMs) of fullerene derivatives reduces the hysteresis of perovskite solar cells (PSCs). We have investigated three different fullerene derivatives observing a decrease on hysteresis ...

    • closedAccess   Conjugated Organic Cations to Improve the Optoelectronic Properties of 2D/3D Perovskites 

      Rodríguez Romero, Jesús; Clasen Hames, Bruno; Mora-Sero, Ivan; Barea, Eva M American Chemical Society (2017)
      Use of C6H5NH3I as an organic cation instead of CH3(CH2)3NH3I in the synthesis of 2D/3D perovskites (C6H5NH3I)2(CH3NH3I)n−1(PbI2)n leads to a material with significantly improved photovoltaic and optoelectronic properties ...

    • openAccess   Electron injection and scaffold effects in perovskite solar cells 

      Anaya, Miguel; Zhang, Wei; Clasen Hames, Bruno; Li, Yuelong; Fabregat-Santiago, Francisco; Calvo, Mauricio E.; Snaith, Henry J.; Míguez, Hernán; Mora-Sero, Ivan Royal Society of Chemistry (2016-12)
      In spite of the impressive efficiencies reported for perovskite solar cells (PSCs), key aspects of their working principles, such as electron injection at the contacts or the suitability of the utilization of a specific ...

    • openAccess   Influence of the substrate on the bulk properties of hybrid lead halide perovskite films 

      Climent-Pascual, Esteban; Clasen Hames, Bruno; Moreno Ramírez, Jorge S.; Álvarez, Ángel Luis; Juarez-Perez, Emilio J.; Mas, Elena; Mora-Sero, Ivan; De Andrés, Alicia; Coya, Carmen Royal Society of Chemistry (2016-10)
      In addition to the known effect of the substrate on the interfacial properties of perovskite films, here we show that the bulk properties of hybrid lead halide perovskite films depend on the type of substrate used for film ...

    • openAccess   Structural characterization of bulk and nanoparticle lead halide perovskite thin films by (S)TEM techniques 

      Fernández Delgado, Natalia; Herrera, M.; Delgado, F. J.; Tavabi, Amir Hossein; Luysberg, M.; Dunin-Borkowski, R. E.; Juarez-Perez, Emilio J.; Clasen Hames, Bruno; Mora-Sero, Ivan; Suárez, Isaac; Martínez-Pastor, Juan P.; Molina, S. I. IOP Publishing (2019)
      Lead halide (APbX3) perovskites, in polycrystalline thin films but also perovskite nanoparticles (NPs) has demonstrated excellent performance to implement a new generation of photovoltaic and photonic devices. The structural ...
