Took the diisopropyl titanate solution with different concentrations as the precursors,TiO2 compact layers series with the thickness of 0～153nm were prepared on the F doped SnO2 substrate (FTO) through the method of spin-coating and then sintering.Subsequently,the compact layers were assembled into perovskite solar cells,and the photovoltaic performance of the solar cells with different compact layers was studied.The result shown that the coverage ratio of the substrate was increased by increasing the thickness of the compact layer,and the substrate will be fully covered in the final.The result of electrochemical properties shown that the schottky barrier at the FTO substrate and TiO2 compact layer interface will increase the charge transfer resistance efficiently,which will further improve the photovoltaic performance of the solar cells.
