“…A few drops of PEG were added to a small amount of TiO 2 /ZnO nanocomposite to make a colloidal solution (photoanode). While the counter electrode was made of graphite powder and a few drops of PEG, the photoanode and the counter electrode were annealed at 300 °C for around 2 h. The photoanode was placed in a chemical dye solution of 0.5% (w/v) MB by the same method, but another photoanode was put in a chlorophyll dye solution extracted from eucalyptus leaves [16]. Then, both electrodes are placed in the dark for about 7-12 h. Then, it is cleaned using ethanol and DW.…”

Various standard methods have previously been used for the synthesis of nanoparticles that produce unhealthy waste. They are also considered unsafe and expensive methods. An alternative technology is needed to synthesize nanoparticles that consume less energy and are more environmentally friendly. In this research, a TiO2/ZnO nanocomposite has been synthesized, which was produced with efficient energy and no environmental pollution using an easy and fast method (electrochemical). Additionally, dye-sensitized solar cells (DSSCs) have been fabricated from TiO2/ZnO nanocomposite which was synthesized by a new green method and pigments (methylene blue as a chemical dye and chlorophyll as a natural dye). These DSSCs were characterized by their high ability to absorb ultraviolet energy, where the efficiency of energy conversion η of ITO-TiO2/ZnO were approximately 2.08, and 3.04% with chlorophyll and methylene blue, respectively, showing that η of ITO-TiO2/ZnO with methylene blue was the best.

“…However, the lower electron injection into the ZnO can reduce the photocurrent efficiency (PCE) [4]. Anand et al [5] produced 1.652 mA with DSSC based on the ZnO nanoflower shape. The energy conversion was at 1.61% with ZnO/ruthenium-based dye [6].…”

For oxide semiconductors for application in dye-sensitized solar cells (DSSCs), titanium dioxide conjugated with zinc oxide thin films was synthesized and characterized. The UV (ultraviolet) spectrum characterization showed a peak of absorbance at around 355 nm, with a band gap of 3.25 eV and reflectance around 85%. Such characteristics allowed the fabrication of DSSCs with N719 dye, under simulated light of 100 mW/cm 2 . The highest efficiency of 1.17% was at 5% titanium dioxide and 4 h of dye immersion.

“…Dye‐sensitized solar cells (DSSCs) are promising candidates for photovoltaic devices owing to their simple fabrication and cost‐effectiveness compared to commercially available solar cells (Anand et al, 2022; Bhullar et al, 2022; Nam & Boo, 2022; Shobana et al, 2022; Wang et al, 2022; Yadav et al, 2022). The performances of DSSCs are primarily determined by the porosity of the photoanode, optical properties, redox reaction, and photochemical properties of molecular sensitizers (Dong et al, 2014; Ganesh et al, 2019; Ganesh et al, 2020; Singh et al, 2022; Xin et al, 2012; Zouhri et al, 2022).…”

Specifically engineered three-dimensional (3D) and 1D morphologies are expected to play significant roles in the development of next-generation dye-sensitized solar cells.In this study, using a hydrothermal approach without a surfactant or template, we attempted to synthesize a 3D hierarchical rutile titanium dioxide (TiO 2 ) architecture by varying the growth temperature and time. X-ray diffraction patterns of the synthesized TiO 2 correlated well with rutile TiO 2 . Scanning electron microscopy images exhibited different nanostructures, such as nanorods, aggregated nanorods, and 3D TiO 2 microflowers comprised of nanorods at 100 C, 130 C, and 160 C, respectively, after growth for 6 h. A significantly improved efficiency was observed for the TiO 2 microflowers. The TiO 2 microflowers exhibited an efficiency of 1.16%, short-circuit current density of 12.8 mA cm À2 , open-circuit voltage of 0.692 V, and fill factor of 0.67.
