ZnO nanoparticles were synthesized via the sol-gel method, and five DSSC samples (DS1-DS5) were fabricated using the Doctor Blade technique. These were sensitized with: (1) jujube extract (D1), (2) Nerium extract (D2), (3) N719 (D3), (4) a blend of D1 and D2 (D4), and (5) a co-sensitized mix of D1, D2, and N719 (D5) in a 1:1:2 ratio. Structural and optical properties were characterized using FE-SEM, XRD, and UV–Vis spectroscopy, while photovoltaic performance was evaluated with a solar simulator. Results revealed that DS5, co-sensitized with all three pigments, exhibited the broadest absorption spectrum (200–600 nm) and the highest efficiency (3.28 %), attributed to enhanced light harvesting and electron transfer. The ZnO films showed a uniform, porous structure with an average nanoparticle size of 42.16 nm. This co-sensitization approach, combining low-cost natural dyes with N719, offers an eco-friendly and efficient strategy for improving DSSC performance.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"10 ","pages":"Article 100868"},"PeriodicalIF":3.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural, morphological, compositional and optical properties of prepared photocatalysts were characterised by X-ray Diffraction, Fourier transform infrared spectroscopy, High-resolution scanning electron microscopy, High-resolution transmission electron microscopy, Energy dispersive X-ray spectroscopy and Ultraviolet diffuse reflectance spectroscopy respectively. XRD validated the orthorhombic crystal structure of nanoparticles in the <em>Pbnm</em>space groupwith the reduction of average crystallite size from 32.74 to 24.97 nm upon Ce substitution. FTIR verified the presence of the distinctive Fe-O bond. The morphological study also revealed that the materials were porous. The samples were identified as visible-light-driven photocatalysts, with the reduction of optical band gap from 2.24 to 1.88 eV with increasing Ce concentration. The role of visible light exposure on synthesized nanoparticles was studied. Bare lanthanum ferrite degraded only 56 % of tetracycline. However, cerium-substituted lanthanum ferrite nanoparticles have shown maximum degradation of 91 %. The estimated degradation rate constant of La_0.8Ce_0.2FeO₃ was found to be 3 times greater than the bare sample and follows pseudo-first order kinetics.The main active species involved in degradation was identified as superoxide radicals.
