A low-temperature-sintering TiO2 paste prepared using a simple route designed to induce secondary agglomeration was applied to dye-sensitized solar cells (DSSCs). This approach induces light scattering that improves the electron transport Lime, recombination time, and charge collection efficiency of the DSSCs. 2PH (first layer: HNO3-treated P25, second layer: TiO2 bulk macroparticles of agglomerated hydrothermally synthesized TiO2 particles)-based DSSCs showed excellent properties, with the fastest electron transport time (6.8 x 10(-4) s), slowest recombination time (8.0 x 10(-2) s), and highest charge collection efficiency (99.1%). Compared with a 2H-based device 2H(2.69%), photoelectric conversion efficiency of 2PH(5.42%) improved about 200%.
