The key advantage of using vertically aligned one-dimensional (1-D) metal oxide nanostructures as A component for the hybrid devices is the capability to provide direct and stable pathways for the transport of photogenerated electrons toward the collection electrode.
使用垂直针状一维(1-D)金属氧化物纳米结构材料作为构成复合器件A组分的突出优势在于它可以提供面向集电环的光致电子输送路径。
The bulk heterojunction with vertically aligned 1-D nanochannels for electron transportation has been regarded as an ideal structure for polymer-based solar cells. ZnO has recently been of great interest in the preparation of such aligned 1-D structures for this purpose, due to its high electron mobility and easy availability at low temperature by controllable synthesis.
用来输送电子的由垂直针状一维纳米管道构成的体异质结材料被认为是制备聚合物基太阳能电池的理想材料。为了达到此目的,用ZnO来制备这种针状一维结构材料近来引起了人们广泛的兴趣,这是由于ZnO的高电子迁移率以及其在低温下的可控合成。
The aligned ZnO nanorod arrays prepared by hydrothermal reaction have normally been used for hybrid polymer/ZnO solar cells, but the power conversion efficiency (η)of0.2 0.5% is not high yet.
通常用来制备聚合物/ZnO复合太阳能电池的的ZnO纳米棒阵列是通过水热反应合成的,但它的光电转换效率不高,仅为0.5%。
The hydrothermal method generally produces ZnO nanostructures containing many deep level defects, which will significantly influence the transport of photogenerated charges toward the collection electrode by trapping/detrapping electrons.
水热法制备ZnO纳米材料会形成很多深层次的缺陷,这会在很大程度上通过捕获/释放电子过程影响到光致电荷的迁移。
In contrast, the ZnO nanostructures synthesized by electrodeposition contain much less defects, offering a low-temperature technique for the low-cost growth of high quality ZnO crystals.
相比之下,通过电沉积法合成ZnO纳米结构材料形成的缺陷就很少,这就提供了一种低温低成本下生长高品质ZnO晶体的方法。
Very recently, Atienzar and co-workers showed the first application of the electrodeposited ZnO nanorod arrays for hybrid polymer/ZnO solar cell devices with an efficiency of η 0.025% under AM 1.5 illumination.
近来,Atienzar及其同事们第一次用电沉积法合成的ZnO纳米棒阵列制备了在AM1.5光照射下效率可达0.025%的聚合物/ZnO太阳能电池器件。
Even though dramatic improvements have been achieved on the device construction and processing of the photoactive layer of polymer/ZnO nanorod array devices,the relationship between the intrinsic property of ZnO nanorods and the device performance, which is crucially important for improving cell performance, still remains unclear.
尽管在器件结构和聚合物/ZnO纳米棒阵列形成器件的光敏层的加工工艺上都取得了很大的发展,但是,有一点对提高电池性能是很重要的,就是ZnO纳米棒的固有性质和器件性能之间由什么关系?这仍然悬而未解。 |
