High Efficiency and High Open Circuit Voltage in Quasi 2D Perovskite Based Solar Cells
© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim wileyonlinelibrary.com (1 of 7) 1604733 configuration is of the structure R2(CH3NH3)n–1MnX3n+1, where R is an organic group, M is a divalent metal, and X is a halide (Cl−, Br−, or I−). The number of perovskite layers are determined by the long organic groups separated by the MX6 layers.[8] In this work, quasi 2D perovskites were synthesized whic...
متن کاملBication lead iodide 2D perovskite component to stabilize inorganic a-CsPbI3 perovskite phase for high-efficiency solar cells
Among various all-inorganic halide perovskites exhibiting better stability than organic-inorganic halide perovskites, a-CsPbI3with themost suitable band gap for tandem solar cell application faces an issue of phase instability under ambient conditions. We discovered that a small amount of two-dimensional (2D) EDAPbI4 perovskite containing the ethylenediamine (EDA) cation stabilizes the a-CsPbI3...
متن کاملافزایش پایداری سلولهای خورشیدی با استفاده از لایههای جاذب پروسکایتی CH3NH3PbI3 آلاییده با برم
The CH3NH3PbI3 is one of the most widely used and famous lead halide perovskite absorber layer for using in perovskite solar cells. One of the ways to deal with the instability problem of this perovskite structure in environmental condition is bromide doping in this composition. In this work, the structural and optical properties of the bromide doped CH3NH3PbI3 absorber layers were studied as w...

متن کاملEffect of Cs on the Stability and Photovoltaic Performance of 2D/3D Perovskite-Based Solar Cells
One of the attractive features of hybrid perovskite is the possibility to reduce its dimensionality, which enhances the perovskite’s resistivity to moisture. In this work, we used 2D/3D perovskites to study different organic molecular spacers (aromatic ring vs cyclic ring); Cs was introduced as an additional small cation to methylammonium. It was found that Cs improves the photovoltaic performa...
