TEMPLATE ASSISTED ELECTRODEPOSITION OF HIGHLY ORIENTED ZnO NANOWIRE ARRAYS AND THEIR INTEGRATION IN DYE SENSITIZED SOLAR CELLS

Dye sensitized solar cell (DSSC) based on N719 dye sensitized zinc oxide nanowires prepared by template assisted electrodeposition was investigated. The morphology and crystalline structure of highly oriented nanowires were characterized by scannnig electron microscopy and X-ray diffraction, respectively. The photovoltaic performance of the DSSC was characterized at full sun intensity of 100 mW/cm2 obtaining a shortcircuit current of 4.8 mA/cm2, an open circuit voltage of 0.64 V and energy conversion efficiency of 1.23 %.
