Fig. 5(A) shows the J–V curves of DSSCs prepared by using paste-3 and paste-1 (see the explanation in Table 1). The DSSCs show typical and good J–V dependences (high fill factor), indicating that the DSSCs with good structures have been made. Fig. 5(B) shows the external quantum efficiency (EQE) of DSSCs made from paste-3 and paste-1. As compared to the DSSCs made of the TiO2 nanoparticles, it can be seen that the TiO2 sphere material can obviously increase the light-scattering effect from 600to 700 nm.
