“…However, beyond these temperatures, the J sc values of all of the devices gradually decreased; this could be ascribed to the recombination of ions. A similar trend of increasing and decreasing in J sc with increasing temperature was reported in other works …”

New gel polymer electrolytes (GPEs) were prepared via the blending of a polyacrylonitrile polymer and a poly(1‐vinyl pyrrolidone‐co‐vinyl acetate) copolymer. The sodium iodide (NaI) salt concentration was varied for each GPE sample. From ionic conductivity (σ) studies, we observed that the sample with a 40 wt % NaI salt content (N40) showed the highest σ of 3.54 × 10−3 ± 0.05 S/cm at room temperature, and all of the GPE samples obeyed Arrhenius behavior. The dielectric properties of the GPE samples were also analyzed to study the electrical polarization of the materials. The developed GPE samples were also characterized with X‐ray diffraction and Fourier transform infrared spectroscopy. We also then used the developed GPE samples for the fabrication of dye‐sensitized solar cells by sandwiching them between a photoanode and Pt counter electrode for photovoltaic studies. The highest photovoltaic performance was achieved by N40, with an efficiency of 3.04%. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47810.

“…Remarkably, the gel electrolytes formed from the LMOGs exhibit three dimensional networks and possess higher ionic conductivity, good pore filling and penetration of the mesoporous TiO2 film [21,22]. Importantly, the devices assembled by LMOGs exhibit good long-term stability because of a high gel to solution transition temperature of LMOGs [23,24].…”

A low molecular mass organogelator (LMOG), N,N¢ -1,5-pentanediylbis-dodecanamide, was applied to quasi-solid-state dye-sensitized solar cells (QS-DSSCs). The crosslinked gel network was self-assemblied by the LOMG in the liquid electrolyte, and the in situ assembly process of gelator can be obtained by the polarized optical microscopy (POM). On one hand, the network hinders the diffusion of redox species and accelerates the electron recombination at the interface of the TiO2 photoanode/electrolyte. On the other hand, Li + can interact with the amide carbonyl groups of the gelators and the adsorption of Li + onto the TiO2 surface decreases, leading to a negative shift of the TiO2 conduction band edge, accelerated electron transport and decreased electron injection efficiency (ηinj) of QS-DSSC. As a result, the incidental photon-to-electron conversion efficiency (IPCE), the short circuit photocurrent density (Jsc) and the open circuit voltage (Voc) of the QS-DSSC are decreased compared with those of the liquid electrolyte based DSSC (L-DSSC), which indicates that the electron recombination plays a great role in the photovoltaic performances of DSSC. Remarkably, the QS-DSSC exhibits excellent thermal and light-soaking stabilities during accelerated aging tests for 1000 h, which is attributed to a great intrinsic stability of the gel electrolyte with a high gel to solution transition temperature (Tgel = 108°C).
