Characterization techniques, including AFM, optical absorption, SEM, XRF, EIS, and J-V curve analyses, demonstrated that the hybrid material broadens light absorption to wide wavelengths, improving photon harvesting from solar radiation and aligning well with the absorption range of N-3 dyes. The difference in conduction band edges between BaTiO₃@CaF₂ and TiO₂ promotes efficient charge separation, reduces recombination, and facilitates directional electron transport, resulting in an open-circuit photovoltage of up to V_oc = 782 mV.
