“…3 An alternative anchoring group is the phosphonic acid that binds even more strongly onto TiO 2 . Grafting sensitizers on the surface of TiO 2 with the phosphonic acid group has been reported earlier by us [4][5][6] and other groups. [7][8][9][10][11][12][13] Recently, we have demonstrated the significance of using an amphiphilic polypyridyl ruthenium sensitizer to achieve unprecedented stability in DSCs at elevated temperatures.…”

A new amphiphilic polypyridyl ruthenium complex, cis-Ru(dpbpy)(dnbpy)(NCS) 2 (dpbpy ) 4,4′-diphosphonic acid-2,2′-bipyridine; dnbpy ) 4,4′-dinonyl-2,2′-bipyridine), was synthesized and demonstrated as an efficient sensitizer. The sensitizer was characterized by NMR, voltammetry, ATR-FTIR, resonance Raman, as well as electronic absorption and emission spectra. Nanocrystalline dye-sensitized solar cells (DSCs) with this new sensitizer generated g8.0% power conversion efficiencies under illumination with simulated air mass 1.5 sunlight. This is the first time such a high solar-to-electricity power conversion efficiency for DSCs has been reached by a sensitizer bearing non-carboxylic acid anchoring groups. Additionally, the devices exhibited excellent stability under light soaking at 55 to 60°C. Time-resolved nanosecond laser experiments revealed that the dye regeneration rate of this new sensitizer seems to be quite similar but the charge recombination is significantly slower in comparison to the analogues carboxylated sensitizer.

“…Presently, DSSC can achieve as much as 10% energy conversion efficiency (Gratzel, 2001). The ongoing research and development focus on new DSSC materials for higher cell efficiency and theoretical modelling for insightful understanding of the basic working mechanisms (Ruile et al, 1997;Gratzel, 2000;Kron et al, 2002Kron et al, , 2003aKron et al, , 2003bRau et al, 2003;Durr et al, 2004;Fredin et al, 2005;Lenzmann et al, 2005;Gratzel, 2006;Ito et al, 2006;Kroon et al, 2006;Kumara et al, 2006;Ni et al, 2006a;Pettersson et al, 2006;Sastrawan et al, 2006). Some studies have been conducted to determine the effect of the TiO 2 electrode thickness on the DSSC performance.…”

The maximum power point (MPP) of a dye‐sensitized solar cell (DSSC) is often more important than the open‐circuit voltage and the short‐circuit current as MPP better represents the DSSC power output and energy conversion efficiency. In this investigation, the DSSC J–V characteristics and MPP were studied using a simple theoretical electron diffusion model. Parametric analyses were performed to determine the particular effect of electrode thickness on the MPP output. The analytical results are well consistent with the experimental results published in the literature. In the optimization analysis, it was specially found that the optimal electrode thickness for the highest MPP is rather insensitive to the operating conditions. It implies that an optimally designed DSSC can be always operated at its highest MPP regardless of any geographical, seasonal, and solar hour factors. Such an important attribute facilitates the design and manufacture of DSSC for worldwide commercialization at competitive costs.
