“…For comparison, roughness of the FTO substrates with and without Pt film is also listed in Table 1. Pt-FTO substrate is highly textured, R a approximately 33 nm, similar to the FTO substrate, which indicates that the Pt film is very thin and retains surface morphologies and topographies of FTO substrates, as was pointed out by Tsai [34].…”

Two novel ruthenium complexes are synthesized and used as photosensitizers in dyesensitized solar cells (DSCs): [RuCl2(mPTA)3(H2O)](CF3SO3)3 (C1) (m: methyl; PTA: 3,5,7-triazaphosphaadamantane) and [Ru(C=C=CPh2)Cp(PTA)(PPh3)](CF3SO3) (C2). The complexes are soluble in organic solvents and, interestingly, in water, which makes them useful for water-based photochemical processes. They possess excellent photon-absorption properties over a wide range of the UV-vis spectrum with intense peaks at ~ 330 nm for both sensitizers and a second peak for C2 at 525 nm, much stronger than the corresponding to dye N719. The performance of DSCs containing these sensitizers are evaluated using different electrolytes in comparison with a reference cell made with N719. The solar cell performance was similar for both complexes and strongly dependent on the electrolyte, with a maximum conversion efficiency of 0.33 % for the iodide/triiodide electrolyte. In spite of presenting low efficiencies, these novel ruthenium dyes produce electricity from light effectively and are highly stable under irradiation conditions.

“…Typical components of a DSSC include a titanium dioxide (TiO 2 ) working electrode, a dye, a platinum (Pt) counter electrode (CE), and an electrolyte [7][8][9][10]. The TiO 2 working electrode, which is used for transporting photoelectrons and exhibits a large surface area for dye adsorption and holes for injecting electrolytes, is a key component of a DSSC [11][12][13]. Although other types of wide bandgap oxides can achieve the same effects (e.g., ZnO [14], SnO 2 [15], Fe 2 O 3 [16], and Nb 2 O 5 [17]), TiO 2 is presently the optimal material for fabricating working electrodes.…”

In this study, nickel oxide (NiO) nanoparticles were added to a titanium dioxide (TiO2) nanoparticle paste to fabricate a dye-sensitized solar cell (DSSC) working electrode by using a screen-printing method. The effects of the NiO proportion in the TiO2 paste on the TiO2 working electrode, DSSC devices, and electron transport characteristics were comprehensively investigated. The results showed that adding NiO nanoparticles to the TiO2 working electrode both inhibited electron transport (a negative effect) and prevented electron recombination with the electrolyte (a positive effect). The electron transit time was extended following an increase in the amount of NiO nanoparticles added, confirming that NiO inhibited electron transport. Furthermore, the energy level difference between TiO2 and NiO generated a potential barrier that prevented the recombination of the electrons in the TiO2 conduction band with the I3- ions in the electrolyte. When the TiO2–NiO ratio was 99:1, the positive effects outweighed the negative effects. Therefore, this ratio was the optimal TiO2–NiO ratio in the electrode for electron transport. The DSSCs with a TiO2–NiO (99:1) working electrode exhibited an optimal power conversion efficiency of 8.39%, which was higher than the DSSCs with a TiO2 working electrode.
