摘要：With the continuous development of nanomaterials, how to improve the conversion efficiency of DSSCs has been the focus of scholars. Nano-TiO 2 material is a wide bandgap semiconductor with a bandgap of 3.2eV. It exhibits good performance in dye adsorption, charge separation, electron transport, etc., and has good chemical stability and strong acid and alkali resistance. Therefore, it was always the material of choice for the preparation of photoanodes. In this paper, different thicknesses of TiO 2 NRs barrier layers were prepared on FTO substrates by solvothermal method and two-step spin coating method, and their electrochemical and photoelectric properties were tested by using relevant test instruments. The effects of barrier layers with different thicknesses of TiO 2 NRs on the performance of DSSCs were analysed. The anatase TiO 2 NRs with an average length of 28±10nm and a diameter of 2±1nm were obtained. The concentration of TiO 2 NRs was 0.245mol·L -1 (TiO 2 NRs-12). When the thickness is 88.58nm, DSSCs exhibit the best photoelectric performance.
