Abstract
A sequence of dye-sensitized solar cells is proposed, utilizing TiO(2)@Zn/Al-layered double hydroxide (LDH) as their starting materials, in which Ruthenizer N719 was used as a photon absorber. The anticipated system was turned into sheet-like TiO(2)@mixed metal oxide (MMO) via post-processing treatment. The crystal quality indicated a relation to power conversion efficiency (PCE); this was combined with a comparable morphology profile. In detail, the optimum DSSC device exhibited average sheet-like thickness and a dye loading amount of 43.11 nm and 4.28 ×10-3 mM/cm(-2), respectively. Concurrently, a considerable PCE enhancement of the optimum DSSC device (TiO(2)@MMO-550°) was attained compared to pristine MMO (0.91%), which could be due to boosted electron transfer efficiency. Of the fabricated devices, DSSC fabricated at 550° exhibited the highest PCE (1.91%), with a 35.6% enhancement compared to that obtained at 450°, as a result of its increased open-circuit voltage (3.29 mA/cm(2)) and short-circuit current (0.81 V). The proposed work delivers an enhanced efficiency as compared to similar geometries.
