Efficient nonfullerene organic solar cells with active layers fabricated by water transfer printing

论文摘要

Preparation of high-quality films plays an important role to achieve high-performance nonfullerene（NF）organic solar cells. NF active layer films are typically fabricated by spin coating. Novel fabrication methods to process the NF active layer are desirable to be compatible with large-area production. Herein, we report on the fabrication of NF active layer films via a water transfer printing method. This method delivers a uniform film with controllable film thicknesses. NF active layers of PDBD-T:ITIC and PBDB-T-2 F:IT-4 F were fabricated via the method to validate its effectiveness. Solar cells with the water transfer-printed active layers show comparable performance（up to 11.7%） to the cells with spin-coated active layers. Furthermore, NF solar modules containing 4-sub cells with the active area of 3.2 cm2 are also fabricated via the method. The module shows VOCof up to 3.4 V and a power conversion efficiency of 8.1% with the PBDB-T-2 F:IT-4 F active layer.
