通过微波水热反应制备得到SnO2纳米花状结构,经过600℃退火处理,SnO2的纳米花出现很多孔洞,这种结构具有极大的比表面积,应用于染料敏化太阳能电池光阳极。进一步经过TiCl4优化处理后,电池的光电转化效率提高到了3.95%。电化学性质研究结果表明,电池性能提高的原因是TiCl4处理延长了电荷的寿命。 SnO2 nanoflowers were prepared by microwave hydrothermal reaction. After annealing at 600 ℃, many pores appeared in the nanoscale SnO2 nanoflowers. The nanostructured SnO2 nanomaterials had very large specific surface area and were used in photoanode of dye-sensitized solar cells. After further optimization of TiCl4, the photoelectric conversion efficiency of the battery increased to 3.95%. Electrochemical properties The results show that the reason for the improvement of battery performance is TiCl4 treatment to extend the charge life.
