Graphite nanopowder is synthesized by mechanical method using ball mill and used as filler in polymer electrolyte film based on Polyvinyl alcohol (PVA) for application in natural dye sensitized solar cell (DSSC). In the present work dye sensitized solar cell has been assembled using electrolyte system composed of PVA as host polymer, ethylene carbonate as plasticizer, LiI: I2 as redox couple and graphite as filler; TiO2 modified with Copper oxide (CuO) photoanode in order to provide inherent energy barrier and natural cocktail dye as sensitizer. The obtained solar cell conversion efficiency was about 3.2 % with fill factor 52% using an irradiation of 100 mW/cm2 at 25º C.

Sensitized Solar Cells

In this work, several liquid electrolytes (LE) have been prepared. The electrolytes contain tetrapropylammonium iodide (TPAI) salt with different salt content, propylene carbonate (PC), ethylene carbonate (EC), polyethylene oxide (PEO), dimethylformamide (DMF) and (I-/I3-) redox couple LE was used in the Dye-Sensitized Solar Cell (DSSC). DSSCs were fabricated and current density-voltage (J-V) characteristics measured. The highest incident photon conversion efficiency (IPCE) at 520 nm is 45.5% for DSSC with 0.25 g TPAI LE. At AM 1.5, DSSC with LE exhibits efficiency of 6.61% with Jsc= 18.69 mA cm-2, Voc= 0.68V and fill factor (FF) = 0.52.

Abstract The ionic conductivity of poly(glycidyl methacrylate-co-ethyl methacrylate) [P(GMA-co-EMA)]-lithium perchlorate (LiClO4)-ethylene carbonate (EC) electrolyte and photovoltaic performances of dye-sensitized solar cells (DSSC) utilizing the electrolyte were investigated. P(GMA-co-EMA) as a host material of the electrolyte was synthesized by UV-curing and characterized by nuclear magnetic resonance (NMR). P(GMA-co-EMA) based solid polymer electrolyte containing 80 wt% EC exhibited the highest room temperature ionic conductivity. The crystallinity degree of the electrolyte decreases with the EC content, as confirmed by X-ray diffraction (XRD) studies. The electrochemical stability investigated by cyclic voltammetry (CV) reveals that the electrolyte is stable up to 4.8 V. A dye-sensitized solar cell of fluorine tin oxide (FTO)/TiO2-dye/P(GMA-co-EMA)-LiClO4-EC/Pt possessed the photovoltaic effect with a short-circuit current density (Jsc) of 4.85×10-3 mA cm-2 and open circuit voltage (Voc) of 0.4 V, respectively, under light intensity of 100 mW cm-2.
