Controlling the electronic interface properties in polymer-fullerene bulk-heterojunction solar cells

拟议的研究项目旨在研究有机太阳能电池中的界面形成。本论文将合成一系列不同掺杂浓度的氧化锌前驱物，并将其作为有机太阳能电池的n型界面层进行测试。将建立一方面金属氧化物的掺杂水平和功函数与另一方面太阳能电池的Voc和器件性能之间的相关性。通过实验结果与模拟结果的比较，将讨论有机太阳能电池中界面材料功能的基本方面：·第二二极管的起源·表面复合·电极界面的稳定性

The proposed research project aims to investigate the interface formation in organic solar cells. A series of ZnO precursors with different doping levels will be synthesized and tested as n-type interfacial layer in organic solar cells. The correlation between the doping level and the work function of the metal oxide on the one hand and the Voc and device performance of the solar cell on the other hand will be established. From the comparison between experimental results and simulation, fundamental aspects in the function of interface materials in organic solar cells will be addressed:• The origin of a 2nd diode• Surface recombination• Stability of electrode interfaces
