Paper Abstract

Fe-doped mesoporous TiO2 (M-TiO2-Fe) thick films were prepared by sol-gel and screen printing process. Raman characteristics results show that the M-TiO2-Fe thick film possesses a certain degree of the anatase phase, which may have advantages on photocatalysis and photovoltaic ability. Derived from small angel X-Ray diffraction (SAXRD), the films exhibit mesoporous structure with pore size around 7-8 nm. Eg of the films was obviously narrowed from 3.4 eV to 3.0 eV, which allows the thick films using more light to initiate photovoltaic process. Dye-sensitized solar cell (DSSC) based on M-TiO2-Fe was structured and chlorophyl was used as sensitizers. The solar cells have an open circuit voltage above 260mV.
