Abstract


SnO2 (x)- ZnO(1-x) binary system with two different SnO2 composition (x= 3, 5 mol%) were prepared by solid state reaction at high temperature employed as photoanode for dye sensitized solar cell(DSSC) fabrication. SnO2-ZnO binary oxide was characterized by X-ray diffraction(XRD) and UV-VIS Spectroscopy to examine their structure and optical properties. High performance carbon electrode was prepared onto glass and used as counter electrode. Coffee powder was used as natural dye-sensitizer. The improvement in device efficiency was achieved by larger SnO2 composition. The overall power conversion efficiency increased from 0.18% for SnO2:ZnO (3:97mol %) device to 0.26% for a device with SnO2:ZnO (5:95mol %) photoanode.

Author Keywords: Binary oxide, XRD, DSSC, conversion efficiency, fill factor.
