Abstract
In this work we have synthesized Zinc oxide ZnO tripods and used its thin film as photoanode in dyesensitized solar cells SEM micrographs of the asprepared sample of ZnO confirmed tripodlike morphology consisting of three cylindrical arms with welldefined ends joined at a common core The prepared sample of ZnO tripods was further characterized by EDX XRD UVVIS and FTIR The dye N719sensitized solar cell fabricated with photoanode of ZnO prepared in this work provided the opencircuit photo voltage V oc = 0558 V shortcircuit photocurrent J sc = 6368 mA cm2 fill factor FF = 050 and total conversion efficiency η = 088 under full light illumination intensity 200 mW cm−2 When cell was illuminated by visible light 150 mW/cm2 V oc = 0546 V J sc = 4437 mA/cm2 FF = 054 and η = 088 were obtainedFinancial support from the Ministry of New and Renewable Energy MNRE New Delhi India and Council of Scientific and Industrial Research CSIR New Delhi is gratefully acknowledged Thanks are also due to Indian Institute of Technology Banaras Hindu University Varanasi India for providing their facilities XRD and SEM during this work
