One of the most promising architectures of third generation solar cells is integration of single crystalline nanowires as electron transporters in anodes of electrochemical cells. The nanowire-based cells aim at significantly increase cell efficiency thanks to the higher mobility of electrons along the single crystalline lattice of the nanowires with respect to traditional polycrystalline networks,...
ZnO nanocrystals were prepared from the decomposition of zinc(II) 2-ethylhexanoate. Soluble nanocrystals with a size ranging from about 5 to 8 nm were obtained. The powders obtained were tested as optical gas sensor based on photoluminescence (PL) variation with NO2, ethanol and relative humidity at room temperature (RT). The surface capping of the ZnO nanocrystals was modified by substituting the...
Interest in nanowires of metal oxides has been exponentially growing in the last years, due to the attracting potential of application in electronic, optical and sensor field. We have focused our attention on the sensing properties of semiconducting nanowires as conductometric and optical gas sensors. Single crystal nanostructures In2O3, SnO2, and ZnO were synthesized to explore and study their capability...
In this paper, investigation on novel hybrid poly (3-hexylthiophene)-ZnO nanocomposite thin films and their gas sensing electrical characterization is reported. Nanocomposite films were studied by Fourier transform infrared (FTIR) spectroscopy and their sensing properties were characterized by volt-amperometric technique. All films contain typical peaks of pure P3HT however, several differences in...
