NHE were converted to electron volt (eV) as shown in eqn (1).The GSOP value of −5.46 for HD-1-mono confirmed that the HOMO of this dye is below the I3−/I− redox couple (−5.2 eV), and the difference is large enough for electron replenishment and efficient dye regeneration.

A higher η value of 7.50% was achieved for the DSSC with HTiO2 as the light scattering layer, as compared with those of 6.70% and 6.61% for the DSSCs with CTiO2 and commercial TiO2 as the light scattering layer, and of 6.41% for the cell without a light scattering layer in the photoanode.

The study presented here is far from being fully optimized, but the preliminary results along with cost-effective and scalable components suggest the alloy NiM CEs holding great promise in developing high-performance DSSCs and the launched reduction rate constant having commonality in comparing the catalytic activity of CE electrocatalysts.Supplementary data associated with this article can be found, in the online version, at

Finally, 80nm thick Ag was thermally evaporated on the top of HTM to produce a completed PeSC device.The current–voltage characteristics of the solar cells were measured by a computer-controlled Keithley 2400 source meter measurement system with an AM1.5G filter at a calibrated intensity of 100mWcm−2 illumination, as determined by a standard silicon reference cell (91150V Oriel Instruments).

Use of bio-based SC in Ta-based bimetallic oxides resulted in increased Jsc values in DSSCs from 14.53mAcm−2 (FeTa2O6), 11.71mAcm−2 (CoTa2O6) and 11.07mAcm−2 (CuTa10O26) to 15.16mAcm−2 (FeTa2O6/SC), 15.79mAcm−2 (CoTa2O6/SC) and 15.19mAcm−2 (CuTa10O26/SC), respectively.

The ohmic serial resistance (RS) corresponds to the electrolyte and the FTO resistance and the resistances Rct1, Rct2, and Rdiff relate to charge-transfer processes occurring at the counter electrode, dye-sensitized TiO2 electrode, and Nernstian diffusion within the electrolyte, respectively where τ=le2/D, ω is angle frequency, and D is the diffusion coefficient of the diffusing species The impedance parameters, obtained by fitting the experimental spectra with the equivalent circuit, are shown in .
