Çoban Özkan D.Türk A.Çelik E.2024-07-222024-07-22202209574522http://akademikarsiv.cbu.edu.tr:4000/handle/123456789/12742In the present work, structural, microstructural, thermal, magnetic and optical properties of LaFe0.5Mn0.5O3 prepared perovskite powders were exclusively compared for processing temperatures for applications of dye-sensitized solar cells. In this framework, LaFe0.5Mn0.5O3 perovskite powders were synthesized with the sol–gel method at 500 °C and 850 °C (according to DTA/TG results). They were characterized through DTA/TGA (Thermogravimetric and Differential Thermal Analysis), FTIR (Fourier Transformed Infrared Spectroscopy), XRD (X-Ray Diffractometer), XPS (X-Ray Photoelectron Spectroscopy), PSA (Particle Size Analysis), SEM (Scanning Electron Microscopy), VSM (Vibrating Sample Magnetometer) and UV–Vis Spectrometer. In line with the obtained results, ferroelectric perovskite powders were successfully produced. These powders have crystallite sizes of 27.38–35.74 nm, bandgap values of 1.19–0.93 eV, particle sizes of 28–358 nm and ferromagnetic properties. In addition to the effect of synthesis temperature on LaFe0.5Mn0.5O3 synthesis with these characterization processes, it was found that the production of sustainable and applicable dye-sensitized solar cells using LaFe0.5Mn0.5O3 powders can be useful as innovative and futuristic approaches. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.EnglishCrystallite sizeDifferential thermal analysisDye-sensitized solar cellsFourier transform infrared spectroscopyIron compoundsLanthanum compoundsManganese compoundsOptical propertiesParticle sizeParticle size analysisPowdersProcessingScanning electron microscopySolsSpectrometersThermogravimetric analysisX ray photoelectron spectroscopyX ray powder diffractionDTA-TGADye- sensitized solar cellsMagnetic and optical propertiesMicro-structuralProcessing temperatureSol- gel methodsSolar-cell applicationsSynthesis and characterizationsSynthesisedThermal-opticalPerovskiteArticle10.1007/s10854-022-08304-8
