Mesoporous TiO2 microspheres (MS) have been synthesized by a microwave-assisted hydrothermal technique. The samples were analyzed by XRD analysis, and it reveals the tetragonal phase of the TiO2 anatase with better crystallinity. The morphological characterization of TiO2 MS was investigated by FESEM and HRTEM. Bright spots observed from SAED analysis helped in determining the crystalline nature of the microspheres. The synthesized products have a surface area and average pore diameter of 89 m2g−1 and 11.28 nm. The power conversion efficiency of TiO2 MS-based device exhibits a higher PCE of 7.40% compared to commercial P25-based (4.48%) device. The enhanced performance of DSSC is due to its strong light-scattering ability and excellent dye loading capacity of TiO2 microspheres. Electrochemical impedance spectral analysis showed that TiO2 microspheres-based device contributes to a higher electron lifetime and increased efficiency. [ABSTRACT FROM AUTHOR] |
