在HF存在下制备了具有暴露的反应性{001}晶面的锐钛矿TiO 2纳米片。通过组装染料敏化太阳能电池（DSSC）中的光阳极，研究了NaOH洗涤的具有暴露的{001}面的TiO 2纳米片的光伏特性。通过暗电流扫描和开路电压衰减扫描，与H2O洗涤的对应物相比，观察到降低的总体效率和增加的复合速率，并且XPS证实钠离子的有害影响是DSSC中这种降低的效率的原因。
Anatase TiO2nanosheets with exposed reactive {001} facets were prepared in the presence of HF. The photovoltaic properties of NaOH-washed anatase TiO2nanosheets with exposed {001} facets were investigated by assembling the TiO2as photoanodes in dye-sensitized solar cells (DSSCs). A decreased overall efficiency and increased recombination rate was observed in comparison with the H2O-washed counterpart by both dark current scan and open-circuit voltage decay scan, and XPS confirmed that the deleterious effect of sodium ions is responsible for this reduced efficiency in DSSCs.
