Organic Solar Cell Fabrication Based on Nanoporous Semiconducting Polymer Films

本项目针对提高有机太阳能电池性能进行基础研究。一种有机太阳能电池的有源层由p型和n型半导体的混合体系组成。由于p/n共混形态的纳米结构不明确，有机电池的能量转换效率（PCE）尚未得到提高。在嵌段共聚物模板体系的基础上，成功制备了纳米多孔半导体薄膜。通过对纳米结构的控制，可以提高有机太阳能电池的PCE和稳定性。

In this project, the fundamental studies on improvements of organic solar cell performance were targeted. The active layer of an organic solar cell consists of a blend system of p-type and n-type semiconductors. Due to the unclear nanostructures of p/n blend morphology, the energy conversion efficiency(PCE) of the organic cells has not been improved yet. The preparation of nanoporous semiconductor films was succeeded based on the template system of block copolymers. Based on the control of nanostructures, enhancement of PCE and stability of organic solar cells could be achieved.
