SrCO_3/TiO_2 composite film electrode was prepared by screen printing technique,and the photoelectric performances of solar cell based on SrCO_3/TiO_2 composite film electrode and TiO_2 film electrode were investigated.The results showed that addition of SrCO_3 could increase short-circuit current density(Jsc),open-circuit voltage (Voc) and fill factor (FF).And the energy conversion efficiency(η)of the solar cell was improved from 3.01%to 3.53%,an improvement of 17.3%.In addition,UV-Vis results showed dye adsorption of the SrCO_3/TiO_2 composite film electrode was larger than that of TiO_2 film electrode.Furthermore,electrochemical impedance spectrum (EIS) measurement confirmed that the SrCO_3/TiO_2 electrode had smaller resistance than TiO_2 electrode,which could improve the electron transport and the performance of solar cell.
