为了提高有机光伏（OPV）的性能，制备有机纳米尺寸的柱阵列是令人着迷的，因为可以实现对阳极和阴极电极具有连续传导的大面积供体/受体异质界面。在这项研究中，我们通过传统的热梯度升华技术，使用由 CuPc 和 3,4,9,10-苝热羧酸二酐 (PTCDA) 堆叠层组成的几纳米大小的触发种子，生长了铜酞菁 (CuPc) 晶体纳米柱阵列。我们通过调整晶体生长条件来优化柱密度，以便将其应用于 OPV 电池。
To enhance the performance of organic photovoltaic (OPV) preparation of organic nanometer-sized pillar arrays is fascinating because a significantly large area of a donor/acceptor heterointerface having continuous conduction to both anode and cathode electrodes can be realized. In this study, we grew cupper phthalocyanine (CuPc) crystalline nanopillar arrays by conventional thermal gradient sublimation technique using a few-nanometer-sized trigger seeds composed of a CuPc and 3,4,9,10-perylene-thermal carboxylic-dianhydride (PTCDA) stacked layer. We optimized the pillar density by tuning crystal growth condition in order to apply it to OPV cells.
