Photoanodes comprising Au nanoparticles (GNPs) and thin TiO2 layers with a stacked structure were fabricated by repeating the application of TiO2 paste and GNP solutions on conductive glass to vary the distribution of GNPs in the TiO2 layer. The plasmon-enhanced characteristics of dye-sensitized solar cells (DSSCs) with such photoanodes were investigated. Both the absorption of the TiO2 layer and the performance of the DSSC are found to be most increased by plasmonic enhancement when GNPs are concentrated near the position in the TiO2 layer, which is the penetration depth of the incident light of wavelength corresponding to the maximum absorption of the N719 dye (~ 520 nm). When a GNP layer with a relatively high density of 1.3 μg/cm2 density was formed at its position, and two GNP layers with a relatively low density of 0.65 μg/cm2 were formed near the front side of the incident light, the short-circuit current density (Jsc) and energy conversion efficiency (η) of the DSSC were found to be 10.8 mA/cm2 and 5.0%, increases of 15 and 11%, respectively, compared with those of the DSSC without GNPs. Our work suggests that optimization of the distribution of GNPs in the TiO2 layer is very important for improving the performance of DSSCs fabricated by utilizing GNPs.Electronic supplementary materialThe online version of this article (10.1186/s11671-017-2285-4) contains supplementary material, which is available to authorized users.

“…11 shows the Nyquist plots for the electrochemical impedance spectra of the DSSC under illumination from Sun simulated AM 1.5 solar light. The typical Nyquist plot for DSSCs usually exhibits three semicircles, which are attributed to redox reaction at the Pt counter electrode, the electron transfer at the TiO 2 /dye/electrolyte interface and Warburg diffusion within the electrolyte (Nath et al, 2013;Aragonès et al, 2013;Adachi et al, 2006;Hsu et al, 2008;Jung et al, 2008;Lee et al, 2013;Mayumi et al, 2014). The equivalent circuit used in our EIS measurement is shown in the inset of Fig.…”

“…has reported that their P(VA-co-MMA)-based GPE were able to maintain the performances of their devices at 96% after 1000 hours 18 . Another group also reported that their Felmion-based gel electrolyte was able to sustain 90% of the efficiency of their DSSCs up to 4392 hours of storage time 19 . This is one of the main reasons for us to use gel polymer electrolytes as one of the main component for our DSSCs.…”

In this study, dye-sensitized solar cells (DSSCs) has been assembled with poly(1-vinylpyrrolidone-co-vinyl acetate) (P(VP-co-VAc)) gel polymer electrolytes (GPEs) which have been incorporated with binary salt and an ionic liquid. The potential of this combination was studied and reported. The binary salt system GPEs was having ionic conductivity and power conversion efficiency (PCE) that could reach up to 1.90 × 10−3 S cm−1 and 5.53%, respectively. Interestingly, upon the addition of the ionic liquid, MPII into the binary salt system the ionic conductivity and PCE had risen steadily up to 4.09 × 10−3 S cm−1 and 5.94%, respectively. In order to know more about this phenomenon, the electrochemical impedance studies (EIS) of the GPE samples have been done and reported. Fourier transform infrared studies (FTIR) and thermogravimetric analysis (TGA) have also been studied to understand more on the structural and thermal properties of the GPEs. The Nyquist plot and Bodes plot studies have been done in order to understand the electrochemical properties of the GPE based DSSCs and Tafel polarization studies were done to determine the electrocatalytic activity of the GPE samples.
