混合结是有机太阳能电池不可或缺的组成部分，然而，在混合电池中制造电子和空穴传输路径仍然具有相当大的挑战性。在此，提出并证明了使用高迁移率有机半导体的横向交替多层结。总共93%的光生电子和空穴在长距离（0.14 mm）上横向收集。在层厚为10 nm的横向交替多层结中，激子收集效率达到75%。完全收集激子和载流子的横向有机交替多层结可以是有机太阳能电池的替代混合结。
Blended junctions are indispensable for organic solar cells; however, the fabrication of electron and hole transport routes in blended cells remains quite challenging. Herein, a lateral alternating multilayered junction using a high-mobility organic semiconductor is proposed and demonstrated. A total of 93% of the photogenerated electrons and holes are laterally collected over a long distance (0.14 mm). The exciton-collection efficiency reaches 75% in a lateral alternating multilayered junction with a layer thickness of 10 nm. A lateral organic alternating multilayered junction that completely collects both excitons and carriers can be an alternative blended junction for organic solar cells.
