Perovskite-based
SrSnO
3
nanostructures doped with indium
are prepared via a facile chemical precipitation method. Prepared
nanostructures are used to assemble the dye-sensitized solar cells
(DSSCs), and their photovoltaic response and electrochemical impedance
spectra are measured. The synthesized samples are subjected to structural,
morphological, optical, and magnetic properties. The X-ray diffraction
pattern confirms the single-phase orthorhombic (Pbnm) perovskite structure.
Local structural and phonon mode variations are examined by Raman
spectra. Electron micrographs disclose the nanorods. The elements
(Sr, Sn, O, and In) and the existence of oxygen vacancies are identified
by X-ray photoelectron spectroscopy analysis. Surface area analysis
demonstrates the higher surface area (11.8 m
2
/g) for SrSnO
3
nanostructures. Optical absorption spectra confirm the good
optical behavior in the ultraviolet region. The multicolor emission
affirms the presence of defects/vacancies present in the synthesized
samples. The appearance of interesting ferromagnetic behavior in the
prepared samples is due to the presence of F-center exchange interactions.
Under the irradiation (1000 W/m
2
) of simulated sunlight,
the DSSC fabricated by 3% In-doped SrSnO
3
exhibits the
highest η of 5.68%. Hence, the blocking layers prepared with
pure and indium-doped samples could be the potential candidates for
DSSC applications.
