The difference in injection is probably due to the D-\(\pi\)-A structure of this organic dye and its coupling with the TiO\({}_{2}\) film. In the Y123 dye, the electron donor moiety is located in the triphenylamine unit, and the acceptor orbitals are on the cyanoacrylate group. Cyclopentadithiophene (CPDT) works as a \(\pi\) bridge between the donor and the acceptor for efficient electron conjugation. This bridge helps to increase the dipole moment and the improvement of the molar extinction coefficient of the dye molecule. However, due to the electron-rich nature of the triphenylamine donor moiety and the CPDT bridge, Y123 dye is also characterized by a charge injection voltage loss due to its high-lying LUMO energy level [31]. The relaxation of the excited state in the Y123 dye molecule competes with electronic injection in the TiO\({}_{2}\) conduction band. While for Ru-based dyes an ultrafast electron injection in the femtosecond time scale has been reported, the electronic injection for the Y123 dye is accurately monitored within 2 ps after excitation of the photoanode [20; 21]. This also depends on the electrolyte: its role is to allow the closure of the circuit and thus allow the regeneration of the dye, a fundamental process to guarantee the cell continuity in operation. One of the most important parameters of this process is the speed, necessary both to avoid the degradation of the dye, and to prevent the back-injection phenomena and, in general, to maximize the delivered current. Transparent or semitransparent electrodes of DSSC are a unique opportunity for use in building-integrated photovoltaics (BIPV) to exploit the light from the interior of the buildings as well as outside. The bifacial structure indeed uses the solar radiation absorption on the front and rear surfaces of the solar cells [32; 33; 34]. Many researchers are active in this field with the aim to exploit this DSSC typical feature. Moreover, the bifacial factor may be used in tandem devices. To take advantage of the bifacial feature, the scattering layer must not be present in the DSSC cell. The scattering layer is an additional thin film (5 \(\upmu\)m) on the semiconductor with nanoparticles larger than 20 nm, with the rule of scattering the light, thus boosting the optical absorption and ensuring adequate light trapping in the device [35; 36]. The purpose of this work is the comparison and the understanding of dynamics that govern the photoelectrochemical properties of two different class of dyes: a ruthenium complex, C106, and an organic donor-\(\pi\)-acceptor compound, Y123, at the same conditions. We utilized two different electrolytes, the commercial (high-stability electrolyte) El-HSE and the homemade J8\({}^{\star}\)[25], and we investigated the device's behavior when measuring from the front and from the rear side with the aim of confirming DSSC as valid candidate for the bifacial application in BIPV. Moreover, we emphasized the DSSC raising PCE ability when the albedo's effect is exploited, reaching PCE values of 12.8% and 10.3% with Y123 and C106, respectively. To the best of our knowledge, in literature, a PCE as high as 12.8% with Y123 dye has not been reported yet, since no one has studied the potential of Y123 under the albedo effect. Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). Light-colored surfaces return a large part of the surwars back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo). We reached one of highest bifaciality factors (BFs) in the literature, of 93%, with C106 dye on a white background, to the best of our knowledge. Concerning the PCE of the two dyes, we find an interesting trend change linked to the TiO\({}_{2}\) thickness. This is related to the different dyes' molecular structures.
