“…However, compared with liquid electrolyte, pure PVDF-HFP based electrolytes remain low ionic conductivity and diffusion coefficient, which decrease conversion efficiency of DSSCs. Hence, various nanomaterials, such as TiO 2 , ZnO, SiO 2 , Al 2 O 3 nanoparticles, clay, graphene nanosheets and carbon nanotubes composite electrolyte, have been employed widely to synthesize composite electrolyte for improving the performance of DSSCs [26][27][28][29][30][31][32]. It is well known that functionalized multi-walled carbon nanotube (FMWCNT) possesses higher conductivity, dispersibility, charge transport and strong capability to increase ionic free volume, but it have been rarely integrated with PVDF-HFP for composited electrolyte [33,34].…”

“…The liquid electrolyte is trapped in the three dimensional network of the host polymer matrix, where ions can move freely. There are various kinds of polymers used for preparing polymer gel electrolyte, which are suitable for DSSCs . DSSCs based on in a blend of polymer of polyvinyl pyrrolidone (PVP) and polyethylene glycol (PEG) containing KI/I 2 , as reported by Jihuai Wu et al obtained a maximum conversion efficiency of 4.01% .…”

A series of quasi‐solid state dye sensitized solar cells (DSSCs) were fabricated with different wt % of carboxy functionalized multi walled carbon nanotubes (c‐MWCNTs) containing poly (vinyl alcohol)/poly (ethylene glycol) gel electrolyte. The structure and morphology of the polymeric gel electrolyte were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive X‐ray spectrum (EDX) analyses. The thermal stability of the polymeric gel electrolyte was evaluated by thermogravimetric analysis. Fabrication of the DSSCs were carried out by sandwiching the poly (vinyl alcohol)/poly (ethylene glycol)/ c‐MWCNT nanocomposite gel electrolyte in between the dye sensitized TiO2 photoanode and platinum‐based counter electrode. However, c‐MWCNTs forms network with channels of PVA/PEG matrix in gel electrolyte which reduces the charge transfer resistance (Rct) of DSSCs, thereby significantly improving the photovoltaic properties of the DSSCs. The maximum photo conversion efficiency (η) of 3.5 % and short circuit current density (Jsc) of 8.80 mAcm‐2 was achieved using an optimum loading of 0.5 % c‐MWCNT.

“…The literature is not poor in the application of CNTs as the counter component of the counter electrode of DSSCs [20][21][22][23]. Mixing aerosol with chemical evaporation deposition, Aitola et al [21] have produced single-walled carbon nanotubes and have deposited film on polyethylene terephthalate substrate.…”

Dye sensitized solar cells (DSSCs) are very sensitive to electrodes, due to either high cost or easy corrosion problems. To minimize these factors, we present DSSCs with cheap carbon nanotubes as counter electrodes. In addition, we suggest replacing the electrolyte (in typical DSSCs) with a solid film of powdered CsSnI3. The electrical behavior (I-Vcharacteristics) of the proposed device has been measured for different shading conditions. In the light of a theoretical model based on the presence of two diodes, the experimental data have been explained, taking into account a new equivalent circuit for the DSSC. These DSSCs may receive different levels of sun radiation, which stimulates the study of partial shading; so, we have studied the effect of different shadow rates on the solar conversion efficiency of a unit of 4-W-connected DSSCs. The validity of the present model has been examined by fitting it intoI-Vcharacteristics at different shading rates.
