Abstract
The main objective of this paper was to enhance the absorption and charge carrier generation rates of DSSC. The functional property of the Eu3+ ion (red light) when infused with the MgAl2O4 host was combined with TiO2 nanoparticles and the results obtained through various studies are elaborated. The host and the nanoparticles were prepared through solid-state and sol-gel routes, respectively, with their crystalline structure and surface morphology identified by X-ray diffraction and field emission scanning electron microscope. The optical characteristics of the sample were studied through photoluminescence (PL) excitation (394 nm) and PL emission spectral analysis. The MgAl2O4: Eu3+ phosphor utilized in DSSC for the light down-conversion process converts high-energy incident light into low-radiation light, which further excites the N719 dye to emit charge carriers, thus increasing the conversion efficiency of the dye-sensitized solar cells. The overall conversion efficiency was observed a 4.80 % when 0.9 MW % Eu3+: MgAl2O4 was added to the TiO2 nanoparticle with an enhanced DSSC performance.
