    • openAccess   Effect of different lead precursors on perovskite solar cell performance and stability 

      Aldibaja, Fadi Kamal; Badia Bou, Laura; Mas, Elena; S. Sánchez, Rafael; Barea, Eva M; Mora-Sero, Ivan Royal Society of Chemistry (2014-12)
      We present the use of halide (PbCl2) and non-halide lead precursors (Pb(OAc)2 (OAc = CH3CH2COO−), Pb(NO3)2, Pb(acac)2 (acac = (CH3COCHCOCH3)−) and PbCO3) for the preparation of perovskite solar cells. We have confirmed by ...

    • openAccess   Interpretation of cyclic voltammetry measurements of thin semiconductor films for solar fuel applications 

      Bertoluzzi, Luca; Badia Bou, Laura; Fabregat-Santiago, Francisco; Gimenez, Sixto; Bisquert, Juan American Chemical Society (2013)
      A simple model is proposed that allows interpretation of the cyclic voltammetry diagrams obtained experimentally for photoactive semiconductors with surface states or catalysts used for fuel production from sunlight. When ...

    • openAccess   New iridium complex as additive to the spiro-OMeTAD in perovskite solar cells with enhanced stability 

      Badia Bou, Laura; Mas, Elena; S. Sánchez, Rafael; Barea, Eva M; Bisquert, Juan; Mora-Sero, Ivan AIP Publishing (2014-07-23)
      A new iridium complex, IrCp*Cl(PyPyz)[TFSI], has been synthesized and used as additive for the hole transporter material, spiro-OMeTAD, in perovskite solar cells. The cells prepared with this Ir additive present higher ...

    • closedAccess   Photoinduced Giant Dielectric Constant in Lead Halide Perovskite Solar Cells 

      Juarez-Perez, Emilio J.; S. Sánchez, Rafael; Badia Bou, Laura; Garcia-Belmonte, Germà; Kang, Yong Soo; Mora-Sero, Ivan; Bisquert, Juan American Chemical Society (2014-06)
      Organic-inorganic lead trihalide perovskites have emerged as an outstanding photovoltaic material that demonstrated a high 17.9% conversion efficiency of sunlight to electricity in a short time. We have found a giant ...

    • closedAccess   Quantum Dot Based Heterostructures for Unassisted Photoelectrochemical Hydrogen Generation 

      Rodenas, Pau; Song, Taeseup; Sudhagar, P.; Marzari, Gabriela; Han, Hyungkyu; Badia Bou, Laura; Gimenez, Sixto; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Bisquert, Juan; Paik, Ungyu; Kang, Yong Soo Wiley (2013-02)
      TiO2 hollow nanowires (HNWs) and nanoparticles (NPs) constitute promising architectures for QDs sensitized photoanodes for H2 generation. We sensitize these structures with CdS/CdSe quantum dots by two different methods ...

    • openAccess   Water Oxidation at Hematite Photoelectrodes with an Iridium-Based Catalyst 

      Badia Bou, Laura; Mas, Elena; Rodenas, Pau; Barea, Eva M; Fabregat-Santiago, Francisco; Gimenez, Sixto; Peris, Eduardo; Bisquert, Juan American Chemical Society (2013)
      The iridium complex [Cp*Ir(H2O)3](SO 4) was used as an organometallic source for the electrodeposition of iridium oxide onto Fe2O3. The new iridium-containing electrode allowed us to study the coupling between the ...
