چکیده
The improvement in the efficiency of inverted perovskite solar cells (PSCs) is significantly limited by undesirable contact at NiOX/perovskite interface. In this study, a novel microstructure-control technology proposed for fabrication porous NiOX films using Pluronic P123 as structure-directing agent and acetylacetone (AcAc) coordination agent. synthesized enhanced hole extraction reduced recombination defects Consequently, without any modification, power conversion (PCE) PSC with MAPbI3 absorber layer improved from 16.50% to 19.08%. Moreover, PCE device composed Cs0.05(MA0.15FA0.85)0.95Pb(I0.85Br0.15)3 17.49% 21.42%. Furthermore, application fabricated on fluorine-doped tin oxide (FTO) substrates enabled large-area PSCs (1.2 cm2) 19.63%. This study provides strategy improving interface high-performance cells.

Annealing Effect on (FAPbI3)1−x(MAPbBr3)x Perovskite Films in Inverted-Type Perovskite Solar Cells
This study determines the effects of annealing treatment on the structure and the optical and electronic behaviors of the mixed (FAPbI₃)1-x(MAPbBr₃)x perovskite system. The experimental results reveal that (FAPbI₃)1-x(MAPbBr₃)x (x ~ 0.2) is an effective light-absorbing material for use in inverted planar perovskite solar cells owing to its large absorbance and tunable band gap. Therefore, good ...
متن کاملDegradation Kinetics of Inverted Perovskite Solar Cells
We explore the degradation behaviour under continuous illumination and direct oxygen exposure of inverted unencapsulated formamidinium(FA)0.83Cs0.17Pb(I0.8Br0.2)3, CH3NH3PbI3, and CH3NH3PbI3-xClx perovskite solar cells. We continuously test the devices in-situ and in-operando with current-voltage sweeps, transient photocurrent, and transient photovoltage measurements, and find that degradation ...
متن کاملNovel Solvent-free Perovskite Deposition in Fabrication of Normal and Inverted Architectures of Perovskite Solar Cells
We introduced a new approach to deposit perovskite layer with no need for dissolving perovskite precursors. Deposition of Solution-free perovskite (SFP) layer is a key method for deposition of perovskite layer on the hole or electron transport layers that are strongly sensitive to perovskite precursors. Using deposition of SFP layer in the perovskite solar cells would extend possibility of usin...

This work reports on incorporation of spectrally tuned gold/silica (Au/SiO2) core/shell nanospheres and nanorods into the inverted perovskite solar cells (PVSC). The band gap of hybrid lead halide iodide (CH3NH3PbI3) can be gradually increased by replacing iodide with increasing amounts of bromide, which can not only offer an appreciate solar radiation window for the surface plasmon resonance e...
متن کاملStrained hybrid perovskite thin films and their impact on the intrinsic stability of perovskite solar cells
Organic-inorganic hybrid perovskite (OIHP) solar cells have achieved comparable efficiencies to those of commercial solar cells, although their instability hinders their commercialization. Although encapsulation techniques have been developed to protect OIHP solar cells from external stimuli such as moisture, oxygen, and ultraviolet light, understanding of the origin of the intrinsic instabilit...
