“…The characteristic frequencies of f ct and f rec represent the reduction rate at the CE=electrolyte interface and the recombination rate at the TiO 2 =dye=electrolyte interface. 26) Surprisingly, by increasing sintering temperature up to 300 °C, the R ct dramatically decreases to 1.54 Ω, a value that is half less than 3.83 Ω for Pt CE, resulting the f ct of CP CE is comparable to that of Pt CE. Therefore, this makes us believe that CP CE is a promising alternative to the Pt CE for low-cost consideration.…”

In this paper we have demonstrated the photovoltaic performance of dye-sensitized solar cells with low-cost carbon paste (CP) based counter electrodes. With sintering CP at 300 °C, the overall conversion efficiency of cells can reach 4.9%, which is comparable to 5.7% of the cells with counter electrode of platinum. After sintering, crystalline quality of CP was improved, resulting in the decrease of series resistance of cells and the increase of the work function of CP. We also showed that the reduction rate of triiodide is significantly enhanced due to the increase of surface area of CP and the energy matching between the reduction potential of triiodide and the work function of CP.

Observation of charge coupling effect is important to characterize the electrical behaviors of triple-junction solar cells (TJSCs). Electric modulus (M) spectroscopy incorporated with adequate lasers is demonstrated to be an effective approach to investigate the internal electrical characteristics of the individual subcells in InGaP/InGaAs/Ge TJSCs. The distinct characteristic peaks of imaginary part of M corresponding to three individual subcells are identified, as specific lasers are applied. The charge coupling between the excited subcell and neighboring subcell is observed, which causes the expansion of the depletion region in the latter. This approach provides the information of charge coupling for the design of TJSCs.
