摘要: Abstract Dye-sensitized solar cell (DSSC) is a promising solution to global energy and environmental problems. However, incompleted dye excitation electron recombination reaction have limited the further enhancement of DSSC efficiency. We present here experimental realization double-layered titanium dioxide/silica nanosphere (TiO2/SiO2) photoanodes with light-scattering behaviors, aiming at markedly enhancing light harvesting excitation. The photoelectric efficiency resultant has been enhanced from 6.21% 8.86% by optimizing preparation technique, yielding 42.7% enhancement. impressive results demonstrated that this strategy in fabricating high-efficiency platforms.
