利用水热法通过改变生长时间,成功地在透明SnO_2:F导电玻璃/TiO_2致密层基底上制备了三种长度、直径、面密度分别为460 nm、40 nm、340μm-2,630 nm、44 nm、330μm^(-2),720 nm、50 nm、320μm^(-2)的TiO_2纳米棒阵列,并通过旋涂辅助连续离子层吸附反应法制备PbS量子点、以spiro-OMe TAD为固态电解质,组装了全固态PbS量子点敏化TiO_2纳米棒阵列太阳电池,系统研究了TiO_2纳米棒阵列的微结构对PbS量子点的沉积和相应太阳电池光伏性能的影响。结果表明,基于TiO_2纳米棒阵列长度为460 nm、630 nm、720 nm微结构的太阳电池,其光电转换效率分别是2.17%、2.96%和2.74%。
The TiO 2 nanorod arrays with the length,diameter and areal density of 460 nm,40 nm and 340 μm^-2, 630 nm,44 nm and 330 μm^-2 ,20 nm,0 nm and 320 μm^-2 were successfully prepared on the substrate of the transparent SnO 2 ： F conducting glass/ compact TiO 2 layer using hydrothermal methods by changing the growth time. PbS quantum dots were deposited by the spin-coating assisted successive ionic layer absorption and reaction procedure,and all solid-state PbS quantum dot sensitized TiO 2 nanorod array solar cells were fabricated using spiro-OMeTAD as the electrolyte. The influence of TiO 2 nanorod array microstructure on the deposi-tion of PbS quantum dots and the photovoltaic performances of the corresponding solar cells was systematically investigated. The re-sults revealed that the solid-state PbS quantum dot sensitized solar cells with the TiO 2 nanorod array length of 460 nm, 630 nm and 720 nm exhibited the photoelectric conversion efficiency of 2. 17% ,2. 96%and 2. 74%.
