“…The curves were fitted with the equivalent circuit and the calculated Rct values are~60.38 Ω and 45.62 Ω for NiO x and 5% Zn-NiO x devices, respectively. Typically, low impedance values are expected for better carrier transport functions [48,49]. The device fabricated using Zn doped NiO x had lower impedance values than those fabricated using pristine NiO x .…”

Combustion processed nickel oxide (NiOx) thin film is considered as an alternative to the sol-gel processed hole transport layer for perovskite solar cells (PSCs). In this paper, NiOx thin film was prepared by the solution–combustion process at 250 °C, a temperature lower than the actual reaction temperature. Furthermore, the properties of the NiOx hole transport layer (HTL) in PSCs were enhanced by the incorporation of zinc (Zn) in NiOx thin films. X-ray diffraction and X-ray photoelectron spectroscopy results revealed that the formation of NiOx was achieved at lower annealing temperature, which confirms the process of the combustion reaction. The electrical conductivity was greatly improved with Zn doping into the NiOx crystal lattice. Better photoluminescence (PL) quenching, and low PL lifetime decay were responsible for better charge separation in 5% Zn doped NiOx, which results in improved device performance of PSCs. The maximum power conversion efficiency of inverted PSCs made with pristine NiOx and 5% Zn-NiOx as the HTL was 13.62% and 14.87%, respectively. Both the devices exhibited better stability than the PEDOT:PSS (control) device in an ambient condition.

“…This study also analyzed the PSC device comprehensively. Analysis methods included current density-voltage (J-V) curve analysis (CH Instruments 6116D, CH Instruments, Inc., Austin, TX, USA), external quantum efficiency (EQE) analysis (QE-R, Enlitech, Kaohsiung, Taiwan), and electrochemical impedance spectrum (EIS) analysis (CH Instruments 6116D, CH Instruments, Inc., Austin, USA) [28][29][30]. The J-V characteristics of the PSCs were measured under illumination of simulated AM 1.5G solar light from a 550-W xenon lamp solar simulator (ABET Technologies Sun 3000 Class AAA, Abet Technologies, Inc., Milford, CT, USA).…”

In this study, four organic solvents including 1,2-dichlorobenzene (DCB), chlorobenzene (CB), methylbenzene (MB), and chloroform (CF) were used as solvents in the [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) electron transport layer (ETL) of perovskite solar cells (PSCs). This study observed the effects of various solvents on the surface morphology of the ETL by using an optical microscope (OM) and scanning electron microscope (SEM). The surface roughness, crystal structure, and surface element bonding of the ETL were observed using an atomic force microscope (AFM), X-ray diffractometer (XRD), and X-ray photoelectron spectroscope (XPS), respectively. The absorption spectrum of the perovskite layer was explored using an ultraviolet-visible (UV-Vis) spectrometer. The characteristics of the PSC device were analyzed in terms of its current density–voltage (J–V) curve, external quantum efficiency (EQE), and electrochemical impedance spectroscopy (EIS) measurements. The results showed that DCB is a solvent with a high boiling point, low vapor pressure, and high dielectric constant, and using DCB as the solvent for ETL, the uniformity, coverage, and surface roughness of the ETL showed better properties. The power conversion efficiency of the PSC in which DCB was used as the solvent achieved a value of 11.07%, which was higher than that of the PSCs in which other solvents were used.

“…Semiconductor technology played a significant role to overcome these crises with minimal environmental problems. Semiconductor material-based solar cells are environmental friendly such as silicon, compound semiconductor, oxides, and organic materials [1,2]. Perovskite material-based solar cells (PSCs) have become the focus due to its high power conversion efficiency rocketing from 3.8% in 2009 up to 25.2% to now [3].…”

The utilization of mixed cations is beneficial for taking the advantages of cations and achieving highly efficient perovskite solar cells (PSCs). Herein, the precisely small incorporation of CH(NH 2) 2 (FA) cations in methyl ammonium lead iodide (MAPbI 3) enables the formation of compact, smooth perovskite film with high crystallinity. Consequently, the short-circuit current and the fill factor of the PSCs based on FA x MA 1-x PbI 3 perovskite are greatly improved, leading to the enhanced device efficiency. The champion PSC based on FA 0.1 MA 0.9 PbI 3 exhibits a remarkably high efficiency of 22.02%. Furthermore, the PSCs based on FA 0.1 MA 0.9 PbI 3 perovskite also show improved device stability. This work provides a simple approach to fabricate high-quality perovskite films and high-performance PSCs with better stability.
