      Comparative study between the pillar- and bulk-type multilayer structures for piezoelectric energy harvesters (Phys. Status Solidi A 8∕2014)

      The research of Dong-Jin Shin, Jung-Hyuk Koh and coworkers (pp. 1812–1817) is focused on the materials, the structure design, and optimized measurement systems for piezoelectric energy harvesters that can be used for future energy sources. Different types of design were considered and compared in order to extract the optimized conditions. Both bulk ceramic structure and ceramic pillars embedded in polydimethylsiloxane (PDMS) were compared and discussed. Also, the design of multi-layered stacked structures was proposed to increase the energy density per area. By measuring the output energy of energy harvesters, the multi-layered structure of ceramic pillars with PDMS proves to be highly efficient for piezoelectric energy harvesting.

      Low temperature thermally stimulated current characterization of nanoporous TiO2 films (Phys. Status Solidi A 8∕2014)

      Mara Bruzzi, Riccardo Mori, Ennio Carnevale, Monica Scaringella and Franco Bogani

      Version of Record online: 12 AUG 2014 | DOI: 10.1002/pssa.201470249

      Among the numerous applications of TiO2 nanoparticles, dye sensitized solar cells (DSSC) have received a growing interest as low-cost devices for photovoltaic energy production. The improvement of their performance requires a better charge separation and collection and then a higher conductivity of the TiO2 matrix, which, being in the nanocrystalline (nc) form, is highly disordered material. It is therefore of utmost importance to determine the role of the defect distribution on the transport properties of nc-TiO2. Thermally Stimulated Currents (TSC) is a powerful technique to analyse those defects, nonetheless, a thorough model to discuss TSC emission in highly disordered materials is still lacking. Both multi-trapping and hopping conduction mechanisms should be considered in principle, but the importance of these two mechanisms is still controversial, also owing to the fact that they predict the same behaviour. Mara Bruzzi et al. (see the Invited Article on pp. 1691–1697) present a set of TSC measurements devised to elucidate the role in the TiO2 conductivity of the localized states induced by disorder. The experimental results are analysed without any a-priori assumption on the conduction mechanism, considering the two mechanisms of multi-trapping and hopping as complementary rather than alternatives.

    1. Low temperature thermally stimulated current characterization of nanoporous TiO2 films (pages 1691–1697)

      Mara Bruzzi, Riccardo Mori, Ennio Carnevale, Monica Scaringella and Franco Bogani

      Version of Record online: 25 APR 2014 | DOI: 10.1002/pssa.201330608

      Thumbnail image of graphical abstract

      The role of localized states in electrical conductivity on nanocrystalline TiO2 for dye sensitized solar cells (DSSCs) has been investigated by thermally stimulated current (TSC) measurements. The theoretical analysis of TSCs in a heavily disordered medium is a quite complex phenomenon. The authors have outlined a procedure of numerical simulation that allows for the extraction of significant parameters, as density of defect states and value of the energy constant of the exponential band-tail distribution. The study shows that in a quasi-equilibrium regime, main conduction mechanism in nc-TiO2 is due to hopping, rather than to free carriers that undergo multi-trapping processes.
