제목 Organic spacer-based quasi-two-dimensional perovskites with improved moisture stability for high-performance planar solar cells
초록 Quasi-two-dimensional (Q-2D) perovskites have shown great potential for application in solar cells due to their intrinsic stability, where the organic spacer dominantly determines the Q-2D perovskite ambient stability and device performance. In this work, a novel Q-2D perovskite photosensitizer was prepared by 2-(4-Methoxyphenyl)ethylamine hydroiodide (MPAI) as organic spacer and methylammonium iodide (MAI) for the fabrication of perovskite solar cells (PSCs). The synthesized MPA0.2MA0.8PbI3 film exhibited the absorption bands at ~760 nm and optical bandgap was estimated as ~1.63 eV. The morphological, optical and photovoltaic properties of Q-2D perovskites were enhanced by adding different amine derivatives i.e. NH4Cl, NH4F, NH4SCN as light-harvesting layer. The fabricated device of configuration FTO/TiO2/MPA0.2MA0.8PbI3/NH4SCN/Spiro-OMeTAD/Au achieved power conversion efficiency (PCE) of ~15.1% with short circuit current density (Jsc) of ~22.9 mA/cm2, open-circuit voltage (Voc) of 1.11 eV and fill factor (FF) value of 0.59.
