“…However, the observed pore volumes and diameters are the smallest, and therefore the surface may not be accessible for the bulky N3 dye molecules. This effect strongly affects the dye adsorption ability, which decreases independently at the highest concentration of surface −OH groups, resulting in poor performance of TiO 2 _Pluronic P123 photovoltaic devices [77]. The final J SC performances should be considered as a sum of both phenomena described above.…”

In this study, titania nanoparticles were obtained using the microwave-assisted technique. Moreover, different surfactants (PEG (Mn = 400), Pluronic P123 and Triton X−100) were used during the synthesis in order to determine their impact on the crystallinity and morphology of the final products. Subsequently, techniques such as XRD, SEM and TEM (performed in high contrast and high-resolution mode), diffuse reflectance spectroscopy (DRS), low temperature N2 sorption (BET model), FTIR and TGA were carried out. Based on the crystallinity analysis of the obtained materials, it was established that the addition of surfactants results in greater (PEG and Triton X−100) or smaller (Pluronic P123) average crystallite size. The main purpose of this study was to use the synthesized nanomaterials in the photodegradation process (in the UV light range) of the model organic pollutants – phenol (20 mg/L) and etodolac (15 mg/L). Furthermore, it was also pointed out that the dye-sensitized solar cells can be a second application for the synthesized titania nanomaterials. The photo-oxidation and photovoltaic tests have shown that the titanium dioxide obtained using the surfactant-assisted microwave method is characterized not only by better photodegradation efficiency of phenol and etodolac, but also by higher photocurrent density compared to the reference titania samples—the pristine TiO2 and commercial P25.

“…Although TiO 2 scattering NPs have already been used in DSSCs for enhancing light harvesting, [26][27][28] the increased thickness (e.g. 4 µm) of the active layer inevitably results in a photovoltage loss.…”

Gold nanoparticles with various sizes have been prepared and deposited on top of the TiO 2 film in dyesensitized solar cells (DSSCs) in order to enhance the light harvesting efficiency. The light scattering effect gradually strengthens as the size of Au nanoparticles increases from 48 to 203 nm. It is impressive that 1 µg cm -2 deposition of 203 nm gold nanoparticles on top of the TiO 2 film enhances the light scattering efficiency remarkably, increasing short-circuit photocurrent from 14.37 mA cm -2 to 17.81 mA cm -2 by 24% and power conversion efficiency from 7.44% to 10.03% by 35%.
