Abstract

Super flexible TCO-free FAPbI_3-xBr_x planar type inverted perovskite solar cells with a 17.9% power conversion efficiency under 1 sun conditions were demonstrated by introducing an APTES (3-aminopropyl triethoxysilane) adhesion promoter between a PET flexible substrate and a AuCl₃-doped single-layer graphene transparent electrode (TCE). Due to the formation of covalent bonds by the APTES inter-layer, the AuCl₃-GR/APTES/PET substrate had excellent flexibility, whereas the AuCl₃-GR/PET substrate and the ITO/PET substrate had significant degradation of the sheet resistance after a bending test due to the break-off or delamination of AuCl₃-GR from the PET substrate and the cracking of ITO. Accordingly, the perovskite solar cells constructed on the AuCl₃-GR/APTES/PET TCE substrate exhibited excellent bending stability and they maintained their PCE at over 90% of the initial value after 100 bending cycles at R ≥ 4 mm.
