摘要：In the present work, polyvinyl-alcohol/titanium dioxide (PVA/TiO 2 ) nanofibers are utilized as a light scattering layer (LSL) on top of the TiO 2 nanoparticles photoanode. The TiO 2 nanoparticles decorated PVA/TiO 2 nanofibers display a power conversion efficiency (PCE) of 4.06%, which is 33% higher than TiO 2 nanoparticles without LSL, demonstrating the incorporation of PVA/TiO 2 nanofibers as LSL reduces the radiation loss and increases the excitation of the electron that leads to high PCE. The incorporation of PVA/TiO 2 nanofibers as LSL also increases the electron life time and charge collection efficiency in comparison to the TiO 2 nanoparticles without LSL.
