Improving photoelectric conversion efficiency of DSSC using ZnO/ZnP composite nanorods

Abstract

Composite nano structure of ZnO with ZnP co-grown on FTO less substrate to improve the photoelectric conversion efficiency of dye sensitized solar cell (DSSC). The morphology of ZnO nanorods and composite nano structure are demonstrated by scanning electron microscope (SEM) images. The heterogeneous interface between transparent conducting oxide (TCO) and nanorods is completely eliminated. In addition to this the composite nano structure significantly improves the performance of DSSC in terms of conversion efficiency.
