柔性电极的光学、电学、表面特性和稳定性是决定柔性光电器件性能的关键因素。以柔性聚合物太阳电池为例，研究兼具高可见光透过率、高导电性、可弯曲、高稳定性和高效载流子提取特性的透明柔性电极是推动该电池实用化的必经之路。本项目拟在前期氧化物、银栅格和超薄纳米银透明电极研究基础上，通过设计构筑多层复合结构的新型表面纳米功能层/超薄金属结构/光学生长与调控层/柔性衬底电极，以两边非对称设计的超薄金属复合结构进一步降低反射提升电极可见光透过率；以氧化物及C12A7:e-电子化合物为表面功能层，调控电极逸出功实现高效载流子提取。研究上述电极在柔性反型聚合物模型太阳电池中电极特性对电池综合性能的影响规律，提高柔性聚合物太阳电池的效率和稳定性。本项目研究将形成柔性透明电极光学、电学和逸出功的独立调控方法，这不仅有助于提升柔性聚合物太阳电池特性，对其他柔性光电器件的发展也有借鉴价值。

With the development of flexible optoelectronic devices, new requirements for transparent conductive electrodes have been put forward. In the case of polymer solar cells, high ductility, high transmittance, high stability and good interface matching are common problems that need to be solved. based on previous work about metal oxide, Ag grid and ultra-thin Ag thin film, this project intends to take traditional ITO/ZnO electrode based polymer solar cell as a reference device, try to design a new flexible electrode with a structure of surface functional layer/conductive ultra-thin metal layer/optical control layer. On the one hand, on the basis of realizing the continuous growth of ultra-thin metal, try to obtain the maximum transmittance through the asymmetric design on both sides. On the other hand, introducing C12A7:e- electride with adjustable work function value as a surface functional layer to obtain a good interface matching. The purpose of this project is to separately regulate the optical, electrical and surface work function properties of the new sandwich electrode, fully understand and clarify the effects of these three characteristics on the performance of the polymer solar cell, which might help further understanding of the common problems of the flexible electrode and mastering the rules towards high efficiency flexible polymer solar cell.
