Abstract

High ordered one-dimensional (1D) Zinc oxide (ZnO) nanowires were grown on FTO substrate by using the hydrothermal method. Nanowires structures were used as the wide band-gap semiconducting photo-electrode in dye sensitized solar cell (DSSCs). Solar cell made from ZnO nanowire at 50 nm radius and several tens micron lengths showed high solar conversion efficiency (eta) of 2.1% and incident photon current efficiency (IPCE) 35% using nanowire/N719 dye/I-/I3- electrolyte. We also compared Ru N719 dye and N3 dye on ZnO nanowire against each other in respect to solar conversion efficiency and IPCE measurements. In the case of the N3 dye on ZnO nanowire conversion efficiency (eta) of 1.32% and IPCE 23% were obtained under an illumination of 100 mW/cm2. It was found that the performance of the Ru N719 dyes was better than about 50% that of the N3 dye in ZnO nanowire dye-sensitized solar cells.

摘要

采用水热法在FTO衬底上生长了高有序一维（1D）氧化锌（ZnO）纳米线。纳米线结构被用作染料敏化太阳能电池（DSSC）中的宽带隙半导体光电极。由半径为50nm、长度为几十微米的ZnO纳米线制成的太阳能电池，使用纳米线/N719染料/I⁻/I₃⁻电解质时，显示出2.1%的高太阳能转换效率（η）和35%的入射光子电流效率（IPCE）。我们还就太阳能转换效率和IPCE测量，将ZnO纳米线上的钌N719染料和N3染料相互进行了比较。在ZnO纳米线上使用N3染料的情况下，在100mW/cm²的光照下，获得了1.32%的转换效率（η）和23%的IPCE。结果发现，在ZnO纳米线染料敏化太阳能电池中，钌N719染料的性能比N3染料约好50%。
