Herein, trace amounts of bithiophene propylammonium iodide (bi-TPAI) are applied to modulate the surface properties of the gas-quenched perovskite. It is found that the bi-TPAI surface treatment has negligible impact on the perovskite morphology, but it can induce a defect passivation effect and facilitate the charge carrier extraction, contributing to the gain in the open-circuit voltage (V oc) and fill factor. As a result, the PCE of the gas-quenched sputtered NiO x-based inverted PSCs is enhanced from the initial 20.0% to 22.0%. Most importantly, the bi-TPAI treatment can largely alleviate or even eliminate the burn-in process during the maximum power point tracking measurement, improving the operational stability of the devices. | Notes: | Zhan, YQ (corresponding author), Fudan Univ, Ctr Micro Nano Syst, Sch Informat Sci & Technol SIST, Shanghai 200433, Peoples R China.; Zhan, YQ (corresponding author), Fudan Univ, Acad Engn & Technol FAET, Shanghai 200433, Peoples R China.; Kuang, YH (corresponding author), Imec, Imo Imomec, Thin Film PV Technol Partner Solliance, B-3600 Genk, Belgium.; Kuang, YH (corresponding author), Imo Imomec, EnergyVille, B-3600 Genk, Belgium.; Kuang, YH (corresponding author), Hasselt Univ, Imo Imomec, B-3500 Hasselt, Belgium. yqzhan@fudan.edu.cn; Yinghuan.Kuang@imec.be |
