Abstract

 IN THIS STUDY, WE INTRODUCED GRAPHITE BASED COUNTER ELECTRODE FOR DYE SENSITIZED SOLAR CELL [1]. THE RESULTS SHOWED, GRAPHITE CAN BE A GOOD COUNTER ELECTRODE IN N719 BASED DYE SENSITIZED SOLAR CELLS. CYCLIC VOLTAMMETRY AND PHOTOVOLTAIC STUDIES SHOWED, THE I3-/I- REDOX COUPLE CAN BE REACTED ON GRAPHITE ELECTRODE. I3- SPECIES CAN BE REDUCED ON THIS ELECTRODE TO I- TYPES AND I- SPECIES CAN BE OXIDIZED TO I3- SPECIES [2]. THIS FACTS MEANS, WE CAN USED THESE ELECTRODE FOR DYE SENSITIZED SOLAR CELLS [3]. ON THE OTHER HAND, PHOTOVOLTAIC RESULTS SHOWED THE SOLAR CELL DEVICES WHICH FABRICATED FROM THIS ELECTRODE HAVE ACCEPTABLE EFFICIENCY AND ANOTHER CHARACTERS. WE DEFINE THE FOUR CHARACTERS FOR DYE SENSITIZED SOLAR CELL SUCH AS SHORT CIRCUIT CURRENT (ISC), OPEN CIRCUIT VOLTAGE (VOC), FILL FACTOR (FF) AND PHOTOVOLTAIC EFFICIENCY (H). SHORT CIRCUIT CURRENT IS MAXIMUM CURRENT OF SOLAR CELL DEVICE IN THE ABSENCE OF POTOVOLTAGE. IF THE SHORT CIRCUIT CURRENT OF SOLAR CELL DEVICE TO REACH ITS MINIMUM VALUE, THE MAXIMUM VOLTAGE (OPEN CIRCUIT VOLTAGE) IS OBTAINED. CYCLIC VOLTAMMETRY OF THIS ELECTRODE SHOWED I3-/I- REDOX COUPLE BY USING NACLO4 AS SUPPORTING ELECTROLYTE IN ACETONITRILE SOLVENT IN 0.05 V.S-1 SCAN RATE AND PT WORK AND COUNTER AND AG/AGCL REFERENCE ELECTRODE HAVE TWO PEAK IN 0.25 V AND 0.75 V FOR THIS ELECTRODE IN FIGURE1. THIS PEAKS NOT FOUND FOR FREE FTO (FLUORINE DOPED TIN OXIDE) ELECTRODE.
