To accelerate commercialization of perovskite technology and its use in multiple application fields, several device processing strategies have been developed. These efforts primarily target scaling-up device fabrication for mass production and enhancing performance for different light sources (sun or indoor light). This work presents a novel 3D/2D perovskite heterostructure by depositing a mixed layer of phenethylammonium iodide (PEAI) and 1,8-diiodooctane (DIO) directly atop the 3D perovskite absorber without a further annealing step. The addition of DIO enables the formation of pure 2D PEA2PbI4 4 (n =1) at room temperature, leading to defect passivation of 3D perovskite surface, improvement in the crystallinity of 2D perovskite, and optimizing the dipole moment at perovskite/hole transport interface. Large-area PSC modules treated with PEAI:DIO achieve remarkable power conversion efficiencies of 17.7 % (32 cm2) and 15.6 % (121 cm2) under 1Sun irradiation. When exposed to indoor illumination with various LED intensities (200, 500 and 1000 lux) the PEAI:DIO engineered module demonstrated efficiency approaching 34 %, among the highest reported so far for large area modules employing perovskite with bandgap below 1.7 eV. Long-term stability tests following the ISOS-D-1 protocol reveal a threefold increase in T80 lifetime compared to untreated devices. (AU) | |
