Development of an organic thin film solar cell with no bottleneck for hole transport using polymer phthalocyanines

在ITO衬底上沉积的一维聚合物酞菁GaPcF薄膜中，聚合物轴线通常平行于衬底。然而，在目前的研究中，它已经成功地获得了高度有序的排列，其中聚合物轴位于衬底上。这使得制造一种没有空穴传输瓶颈的有机薄膜太阳能电池成为可能。然而，由此生产的太阳能电池在光伏特性方面没有改善。这表明GaPcF薄膜表面的电阻随着取向的增加而增加。

In the thin film of one-dimensional polymer phthalocyanine GaPcF deposited on ITO substrate, the polymer axes usually lie parallel to the substrate. In the present study, however, it has been succeeded to obtain a highly ordered alignment in which the polymer axes stand on the substrate. This made it possible to produce an organic thin film solar cells with no bottleneck for hole transport. However, the solar cells thus produced showed no improvement in the photovoltaic characteristics. This suggests that the resistance at the surface of the GaPcF film was increased by the alignment.
