本文主要研究纳米结构杂化太阳能电池中ZnO/聚（3-己基噻吩）（P3 HT）界面的表征，旨在阐明热处理、局部形貌和器件性能之间的关系。提出了一个等效的阻抗模型的设备，使我们能够提取信息的ZnO/P3 HT界面形态及其对光伏性能的影响，通过比较设备与无纳米图案化。结果发现，热处理对性能的影响只在于在界面上，从不同的界面形态的P3 HT取决于ZnO的晶体方向是存在的。
This paper focuses on the characterization of the ZnO/poly(3-hexylthiophene) (P3HT) interfaces in nanostructured hybrid solar cells, aiming to elucidate the relationship between thermal treatment, local morphology, and device performance. An equivalent impedimetric model for the device is proposed, allowing us to extract information about the ZnO/P3HT interface morphology and its impact on the photovoltaic properties by comparing devices with and without nanopatterning. It is found that the influence of thermal treatment on performance lies solely in the interface, resulting from a different interfacial morphology of P3HT depending on which crystal direction of ZnO is present.
