本文讨论了有机半导体中激子扩散长度的可靠测量问题。激子扩散长度是有机太阳能电池工作中一个极其重要的量。我们专注于聚合物P3HT，因为它在太阳能电池中的广泛使用，并能够适应激子扩散的范围内的薄膜与一个单一的扩散常数，表明我们的方法是特别强大的。
The problem of making reliable measurements of exciton diffusion lengths in organic semiconductors is addressed. The exciton diffusion length is an extremely important quantity in the operation of organic solar cells. We focus on the polymer P3HT because of its widespread use in solar cells and are able to fit the exciton diffusion in a range of films with a single diffusion constant, showing that our approach is particularly robust.
