在这篇文章中，我们描述了聚合物富勒烯体异质结薄膜掺杂香豆素染料的光伏性能。虽然本研究中使用的两种染料具有相似的吸收带，但观察到短路电流密度和开路电压的明显差异。特别是，我们发现，可以通过掺杂香豆素307来提高开路电压。这一发现意味着，掺杂有机染料是一个潜在的有效方案，提高开路电压以及体异质结器件的短路电流。
In this article, we describe the photovoltaic properties of polymer–fullerene bulk-heterojunction films doped with Coumarin dyes. Although the two kinds of dye used in this study have similar absorption bands, distinct differences in both short-circuit current density and open-circuit voltage have been observed. In particular, we found that open-circuit voltage could be enhanced by doping with Coumarin 307. This finding implies that doping with organic dyes is a potentially effective scheme for improving the open-circuit voltage as well as the short-circuit current of bulk heterojunction devices.
