Photoanode Modified by PbTiO3 or PbTiO3/TiO2 Nanofibers in Dye-Sensitized Solar Cell

PbTiO3 was used as a dopant and PbTiO3/titanium dioxide (TiO2) nanofibers (NFs) were used as a scattering layer in the photoanode of dye-sensitized solar cell (DSSC). Their effects on the characteristics of the photoanode of DSSC were studied. The DSSC with the modified photoanode by PbTiO3 and PbTiO3/TiO2 NFs was characterized by X-ray diffractometer (XRD), electrochemical impedance spectroscopy (EIS), J-V characterization, and incident photon current efficiency (IPCE) measurement. The results show that PbTiO3 and PbTiO3/TiO2 NFs can improve the photovoltaic characteristics of DSSC photoanode. The DSSC with modified photoanode by PbTiO3/TiO2 NFs shows better photoelectric conversion efficiency (eta). Compared with the DSSC without modification (TiO2 photoanode), the photovoltaic conversion efficiency (eta) of the DSSC with modified photoanode by PbTiO3/TiO2 NFs has increased by 19%. Based on this research, it can be considered that PbTiO3/TiO2 NFs can be used as one of the candidate materials to improve the photovoltaic performance of DSSCs.
