“…As an excellent photocatalyst, titanium dioxide (TiO 2 ) has been widely studied in the field of photoelectrochemistry (PEC) due to its high catalytic activity, environmental stability, nontoxicity, and cheap cost. Nevertheless, its narrow light absorption range, which only includes ultraviolet light with a wavelength below 400 nm, and the rapid spontaneous recombination of photogenerated electron–hole pairs severely limit the further development and photocatalytic applications of TiO 2 . Therefore, it is urgent to explore the effective routes for improving the photocatalytic activity of TiO 2 . It is well known that the presence of a co-catalyst would be in the favor of improving the photocatalytic performances of TiO 2 . Carp et al demonstrated that the use of Pt as a co-catalyst to modify TiO 2 can significantly improve the efficiency of photocatalytic water splitting to produce H 2 .…”

“…For instance, Leijtens et al have shown that the mobility of the materials is heavily dependent on the charge carrier density as well as the morphology employing transient absorption spectroscopy combined with time-resolved photo-conductivity measurements [ 20 ]. Frischknecht et al have shown that P3HT:TiO 2 hybrid solar cells present a relevant dependence of the photocurrent on the incident light wavelength, exhibiting a particularly strong photocurrent enhancement upon UV monochromatic illumination due to the filling of shallow traps that become donor sites with an n-doping effect improving the titania electron mobilities [ 21 ]. It has been demonstrated that the use of time-of-flight (TOF) measurements are quite appropriate for observing the effects of the molecular structures, trap states, scattering centers, and dispersivity on hole/electron carrier transport [ 22 , 23 , 24 , 25 , 26 ].…”

“…The blend of conjugated polymers with nanostructured metal oxides represent promising candidates for hybrid solar cells since these exhibit high solar energy conversion with low cost [ 14 , 15 , 16 ]. Typically, hybrid solar cells are made up of a combination of both inorganic and organic materials [ 17 , 18 , 19 ].…”
