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.
Highlights
IntroductionThe recently discovered thin film cells based on mesoscopic organic and inorganic semiconductors are attractive alternatives due to their three-dimensional structure which offer the prospect of low cost fabrication
The prototype of these family devices is the Dye-Sensitized Solar Cell (DSSC), which accomplishes the photoelectric efficiency over a wide span of visible light spectrum with the association of a sensitizer as light absorbing material having a wide band gap semiconductor of mesoporous morphology

Summary
The recently discovered thin film cells based on mesoscopic organic and inorganic semiconductors are attractive alternatives due to their three-dimensional structure which offer the prospect of low cost fabrication The prototype of these family devices is the Dye-Sensitized Solar Cell (DSSC), which accomplishes the photoelectric efficiency over a wide span of visible light spectrum with the association of a sensitizer as light absorbing material having a wide band gap semiconductor of mesoporous morphology. The DSSC consists of a dye covered, nanocrystalline TiO2 (titanium dioxide) layer and an electrolyte containing a redox mediator (I-/I3-) encapsulated between two glass plates (Bazargan et al, 2011). Transparent conductive indium tin oxide coated glass and Titanium nanoxide powder were used as electrode plates and electron transport layer respectively, carbon black as counter electrode and tri-iodide redox mediator (I-/I3-) were used as electrolyte.
