摘要

研究了有机光伏器件的激子阻挡层(EBL)的工作机制

对于像bathocuproine (BCP)和bathophenanthroline (Bphen)这样的电子阻挡层

主要利用的是他们的强的电子传输能力。而像copper phthalocyanine (CuPc) 作为电子阻挡层则可利用它大的空穴传输能力和较低的HOMO能级。我们还发现当CuPc厚度为10~30 nm 时

CuPc表现出比BCP 和Bphen高的EB特性。文中还较为详细地叙述了CuPc作为电子阻挡层的运行机制。

Abstract

The operation mechanism of exciton blocking layer (EBL) in organic photovoltaic (PV) cells was demonstrated

the EBL materials with higher electron-transporting ability were used such as bathocuproine (BCP)

bathophenanthroline (Bphen)

and so on. However

it was interestingly found that copper phthalocyanine (CuPc) widely used as donor of the PV cells also can be used as EBL materials and under thicknesses of larger than 10 nm the EBL property even is higher than that of traditional EBL consisting of BCP and Bphen

due to its stronger hole transporting ability from the cathode to the CuPc layer.
