我们报道了一种简单、容易的方法，通过配备收集器的静电纺丝方法来制备有序的无机纳米线结构，并展示了由平面排列的二氧化钛纳米线结构形成的混合光伏电池，例如单轴排列的纳米线和多层交叉排列的聚[2-甲氧基，5-(2‘-乙基己氧基)-1，4-苯乙基]纳米线阵列。与随机采集的二氧化钛纳米线电极相比，在1Sun条件下，通过提高电荷收集和传输速率，以及促进聚合物的渗透，可以显著提高功率转换效率至少70%，这取决于二氧化钛纳米线阵列的排列程度。
We report here a simple and easy method of fabricating arranged inorganic nanowire architecture via electrospinning method equipped with a devised collector and demonstrate hybrid photovoltaic cells that are fashioned of planar-aligned TiO2 nanowire architectures such as uniaxially aligned nanowires and multiple layers of cross-aligned nanowire arrays with poly[2-methoxy, 5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene]. The power conversion efficiency can be significantly improved by at least 70% under 1sun condition depending on the degree of aligning TiO2 nanowire arrays through enhancing charge collection and transport rate, as well as facilitating the polymer infiltration as compared to a randomly collected TiO2 nanowire electrode.
