Dye-Sensitized Solar Cell Based on Polyaniline/Multiwalled Carbon Nanotubes Counter Electrode

Abstract

This work presented the successful fabrication of dye-sensitized solar cell using polyaniline base (EB), multiwalled carbon nanotubes (MWCNTs), organic dye (rhodamine B or riboflavin), zinc oxide (ZnO), and indium tin oxide (ITO). The electrical properties of the resultant devices were investigated by measuring the current density voltage (J-V), capacitance voltage (C-V), and impedance measurements under both dark and illuminated conditions. The photovoltaic cell characteristics, that is, open circuit voltage ( oc ), short circuit current density ( sc ), and energy conversion efficiency ( ), were evaluated under illumination and were found to be 0.48 mA/cm 2 , 400 mV, and 0.224%, respectively, for ITO/EB-MWCNTs/ZnO-rhodamine B/ITO heterostructure. Using impedance spectra, it was found that the series resistances of this type of solar cell are 62 and 60 Ω under darkness and illumination, respectively.

A Review of Electrospun Conductive Polyaniline Based Nanofiber Composites and Blends: Processing Features, Applications, and Future Directions

“…However, this is still an emerging topic of research; therefore the studies dedicated to it seem scarce, regardless of the potential shown. An investigation on electrospun PLA/PANI nanofibers for rigid and flexible DSCs [198] and another on PANI/MWCNT counter electrodes [199] are among the few studies conducted.…”

The development of a ternary nanocomposite for the removal of Cr(vi) ions from aqueous solutions

“…18 Polyaniline (PANI) possesses a large amount of amine and imine functional groups, which can interact with metal ions. [19][20][21][22] PANI has been used for adsorbing different heavy metal ions due to its porous structure, regeneration, nontoxicity, insolubility in water, high stability and low cost. 19,20 The incorporation of NPs into PANI does not only solve the agglomeration problem but can also improve the properties of the PANI matrix.…”

Photovoltaic study of chemically engineered nano-titanium oxide loaded polyaniline matrix of architecture ITO/titanium oxide-polyaniline/aluminum

“…In different three protonation concentrations of PANI are zero-protonated, halfprotonated, and fully protonated thin films, current-voltage measurements shows that conversion efficiency of 1.3%. Ebrahim et al [2] reported the dye-sensitized solar cell based on PANi/ multiwalled carbon nanotubes composite as a counter electrode. The electrical properties of fabricated devices analyzed using by measuring current density, voltage, capacitance voltage, and impedance under both dark and illuminated conditions.…”
