A strategy to fabricate nanostructured poly(3-hexylthiophene) (P3HT) films for organic photovoltaic (OPV) cells by a direct transfer method from a reusable soft replica mold is presented. The flexible polyfluoropolyether (PFPE) replica mold allows low-pressure and low- temperature process condition for the successful transfer of nanostructured P3HT films onto PEDOT/PSS-coated ITO substrates. To reduce the fabrication cost of masters in large area, we employed well-ordered anodic aluminum oxide (AAO) as a template. Also, we provide a method to fabricate reversed nanostructures by exploiting the self-replication of replica molds. The concept of the transfer method in low temperature with a flexible and reusable replica mold obtained from an AAO template will be a firm foundation for a low-cost fabrication process of ordered OPVs.
提出了一种通过从可重复使用的软复制模具直接转移方法来制造用于有机光伏（OPV）电池的纳米结构聚（3-己基噻吩）（P3HT）薄膜的策略。柔性聚氟聚醚（PFPE）复制模具允许在低压和低温条件下成功地将纳米结构的 P3HT 薄膜转移到 PEDOT/PSS 涂覆的 ITO 基底上。为了降低大面积模具的制造成本，我们采用有序的阳极氧化铝（AAO）作为模板。此外，我们还提供了一种通过利用复制模具的自复制来制造反转纳米结构的方法。通过 AAO 模板获得的低温下具有柔韧性和可重复使用性的复制模具的转移方法的概念将为有序 OPV 的低成本制造工艺奠定坚实的基础。
