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,...
Zinc oxide nanowire networks have been prepared using evaporation/condensation technique with a modified set-up that allows the control of the doping present in the gas phase during the growth. The doping process has been studied for the development of homo-junctions. ZnO nanowires with uniform copper addition first and then non-uniform doping distribution have been prepared. Morphology, crystalline...
Pt/SnO2 nanowires/SiC based metal-oxide-semiconductor (MOS) devices were fabricated and tested for their gas sensitivity towards hydrogen. Tin oxide (SnO2) nanowires were grown on SiC substrates by the vapour liquid solid growth process. The material properties of the SnO2 nanowires such as its formation and dimensions were analyzed using scanning electron microscopy (SEM). The current-voltage (I-V)...
