    • openAccess   Physical aspects of ferroelectric semiconductors for photovoltaic solar energy conversion 

      Lopez-Varo, Pilar; Bertoluzzi, Luca; Bisquert, Juan; Alexe, Marin; Coll, Mariona; Huang, Jinsong; Jiménez Tejada, Juan Antonio; Kirchartz, Thomas; Nechache, Riad; Rosei, Federico; Yuan, Yongbo Elsevier (2016-10)
      Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and fast transport and charge extraction ...

    • openAccess   Polarization Switching and Light-Enhanced Piezoelectricity in Lead Halide Perovskites 

      Coll, Mariona; Gómez, Andrés; Mas, Elena; Almora Rodríguez, Osbel; Garcia-Belmonte, Germà; Campoy-Quiles, Mariano; Bisquert, Juan American Chemical Society (2015-03)
      We investigate the ferroelectric properties of photovoltaic methylammonium lead halide CH3NH3PbI3 perovskite using piezoelectric force microscopy (PFM) and macroscopic polarization methods. The electric polarization is ...
