Dye-sensitized solar cell based on an electrospun polymer nanocomposite membrane as electrolyte

Abstract

Abstract In this work an innovative quasi-solid state (QSS) polymer electrolyte containing rare earth oxide nanoparticles and ionic liquid has been developed to enhance efficiency and stability of Dye sensitized solar cells (DSSCs). For the fabrication of DSSCs, 3-decyl 1, 2 dimethyl immidazolium tetrafluroborate ionic liquid ([dmim] BF4-)(IL) and Dysprosium oxide nanoparticles (DyNPs) have been synthesized, characterized and introduced into electrospun Polyvinylidene fluoride (PVDF) nanofibers. These were studied by X-Ray diffraction (XRD), Fourier transform infrared (FT-IR), Diffuse reflectance spectroscopy (DRS-UV), Differential scanning calorimetry (DSC), scanning electron microscope (SEM), Transmission electron microscope (TEM) techniques and examined for their electron uptake, porosity and ionic conductivity. Photovoltaic and electrochemical effects of these electrolytes in DSSCs were investigated. From the results, DSSCs assembled with IL and Dy NPs incorporated PVDF nanofibers was found to have a higher conversion efficiency of 6.4 % and it had better stability than liquid electrolyte. This polymer electrolyte based DSSC have been found to be stable and efficient and such electrolytes have a potential for promising future in solar cells.
