Transparent conducting oxides and their performance as substrates for counter electrodes of dye-sensitized solar cells

The dye-sensitized solar cells (DSSC) and thin-layer heterojunctional solar cells have attracted much attention as an alternative to relatively expensive silicon-based solar cells. Among the various photosensitizers used to build these cells, porphyrins have proven to be outstanding candidates due to their strong absorption in the visible region and have established basic and peripheral modification methods to adjust their geometry and electronic structures. Due to the improved spectral properties, the electronic spectra of these materials have been extensively studied. In this paper, the information obtained using both ultraviolet-visible (UV-VIS) and Fourier Transform Infrared (FTIR) spectroscopy have been used to evaluate the use of Pd-TPP (palladium-5,10,15,20-tetraphenyl porphyrin) as sensitizer dye on different glass substrate coated with transparent conducting oxides. The electrical characterization and quantum efficiency results, related with Pd-TPP-sensitized heterojunctional supramolecular solar cells, are also highlighted.

Sensitized Solar Cells

Transparent conducting oxides (TCO) are commonly used in electrodes of dye-sensitized solar cells (DSSCs). The flexible DSSCs presented in this work was changed to be based on stainless steel (StSt) meshes and the mesoporous TiO2 films were fabricated by electrophoretic deposition (EPD) method which consists of repetitive short-term depositions with intermediate drying. The optimum efficiency was found by changing the TiO2 concentration of EPD solution and the potential difference between the electrodes. The experimental results show that the photovoltaic efficiency (η) of the DSSC with an active size of 1 cm2 is 3.25% under an electric field of 60 V/cm and a TiO2 concentration of EPD solution of 1.0wt%.
