Development of quasi‐solid‐state dye‐sensitized solar cell based on an electrospun polyvinylidene fluoride–polyacrylonitrile membrane electrolyte

Abstract

Dye sensitized solar cell (DSSC) has been magnetizing more awareness in current research due to more efficiency. The foremost drawback of the solar cell is the evaporation of organic electrolyte. In order to address this problem, the polyvinylidene fluoridepolyacrylonitrile-Electrospinning Fibrous Membranes were prepared by electrospinning method and the photovoltaic performances were evaluated. The polyvinylidene fluoride and polyacrylonitrile were mixed in N,N 0 -dimethylformamide and acetone at an applied potential of 15 kV. The surface morphology of membrane is interconnected with network structure and a large number of voids were observed from Field Emission Scanning Electron Microscopy images. The electrolyte uptakes up to 310% were observed and it shows an increase in the ionic conductivity up to 6.12 3 10 22 S cm 21 at 25 C. The fabricated DSSCs show open circuit voltage (V oc ) of 0.74 V, fill factor (FF) of 0.65 and short circuit current (J sc ) of 6.20 mA cm 22 at an incident light intensity of 100 mW cm 22 . The photovoltaic efficiency also reached up to 3.09%.

Electrospun Nanofibers Applied to Dye Solar Sensitive Cells: A Review

“…In 2014, M. Sethupathy et al [53], created a DSSCs with a polymeric electrolyte based on a mixture of PVDF [poly (vinylidene fluoride)] and polyacrylonitrile (PAN) (Table 3, entry 1), and although their efficiency was only 3.09%, they achieved an open circuit voltage (Voc) of 0.74 V, similar to the previous reported voltage of electrolytes based on PVDF. In addition, the nanofiber porosity and ionic conductivity was 83.6% and 6.12 × 10 −2 S·cm −1 , respectively.…”

“…Table 3 presents a comparison of electrolytes based on electrospun nanofibers, and their composition, experimental conditions for electrospinning and main results are presented. Nanofiber are shown in ascending order of efficiency [53,54,55,56,57,58,59,60,61,62].…”

“…The results showed that σ increased because of an increase in the polymeric chain vibration amplitude at higher temperatures. The Pearson correlation coefficients, R 2 of all samples, are very close to 1, which concluded that all CGPEs obeyed the Arrhenius behavior 45,46 . Hence, by using the Arrhenius Equation (), activation energy ( E a ) can be determined in the gradient of the graph, which is shown in Table 2: where, k is the Boltzmann constant (eV K −1 ), is the Arrhenius factor and T is the temperature in (K).…”

“…In addition, diffraction peaks at 34° appear and increase gradually. At the same time, the diffraction peaks at 21° gradually change from smooth to sharp, which might be due to the superposition of the diffraction peaks of PVDF with those of Cu(Ac) 2 and Zn(Ac) 2 between 5° and 20° [13,41,42]. The XRD results indicate that there are no new crystalline phases in the CNFMs, and that Cu(Ac) 2 , Zn(Ac) 2 , PVDF and PAN retain their crystalline structure.…”
