Analyze the Absorption Properties and I-V Characterization of Dye Sensitized Solar Cell Using Ruthenium Dye

Abstract

In this study, Dye Sensitized Solar Cells (DSSC) has been fabricated using natural organic dye extracted from Ruthenium Dye and its I-V characterization and absorption properties have been analyzed. It is observed that the selected natural dye absorbed all visible light and supports electrons motion across the semiconductor interface. The dye acts as sensitizer because the titanium dioxide (TiO₂) cannot absorb the visible light itself as it absorbs higher energy ultraviolet light. Carbon coated electrode was used as counter electrode for electrons collection. Photovoltaic parameters like short circuit current density (Jsc), open circuit Voltage (Voc), Fill Factor (FF) and overall efficiency for fabricated cell were 11.52 mA/cm², 0.70V, 0.61 and 4.47% under 110 mW/cm² illuminations respectively. Idea of such cells facilitates to reduce the fabrication cost with fine efficiency.
