“…As shown, humidified cells exhibit a broad band with IPCE value greater than 80% in the wavelength range of 350–900 nm. It can be attributed to the Fabry–Perot resonances effects with efficient coupling into the waveguide modes of the absorber layer 32 . Furthermore, the integrated current density (J int ) is 17.19 mA cm −2 that is increased after humidification to 17.98 mA cm− -2 .…”

The effect of moisture and heat are important challenges in perovskite solar cells (PSCs). Herein we studied the performance of triple-cation PSCs in different operating environmental conditions. Humidified cells exhibited a hopeful character by increasing the open-circuit voltage (VOC) and short-circuit current density (JSC) to 940 mV and 22.85 mA cm−2 with a power conversion efficiency (PCE) of 14.34%. In addition, further analyses showed that hysteresis index and charge transfer resistance decrease down to 0.4% and 1.67 kΩ. The origin of superior stability is ion segregation to the interface, which removes the antisite defect states. Finally, the effect of operating temperature and trap density on structure and performance was also studied systematically.

“…Due to their exponential charge transfer abilities, CNT derivatives were employed successfully to improve the ability of the charge transporter layer, particularly the hole transporter layer (HTLs). 5,26 Mainly metal oxides including (NiO x, 23 V 2 O 5 27 CoO x , 28 Cu 2 ZnSnS 4 , 24 Cu 2 O, 25 and CuSCN 29 ) conductive polymer (PEDOT:PSS, 30 poly(3hexylthiophene) (P3HT), 31 and poly(triarylamine) (PTAA) 32 ) are used to increase the effectiveness of hole extractions from perovskite layer and transfer them to anode of a solar cell device.

“…In inverted PSCs, HTMs play a crucial role in facilitating the efficient extraction of positive charges (holes) generated by the absorption of light in the perovskite layer preventing their recombination with electrons within the perovskite material. − This process is essential for maintaining a high charge carrier separation efficiency and, consequently, a high device efficiency.

Carbon nanotubes (CNTs) are known for their unique photoelectric and mechanical properties, but their manufacturing process often requires high thermal energy. This study presents a simple solvothermal method to produce multiwalled carbon nanotubes (MWCNTs) from acetyl ferrocene at a low temperature of 250 °C. The synthesized MWCNTs were fully characterized and elucidated through X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy. The MWCNTs were then incorporated into poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PE-DOT:PSS) at different weight ratios (2.5, 5, and 10%) as a hole transporter in perovskite solar cells. The results of UV−vis spectroscopy showed that MWCNTs/ PEDOT:PSS did not affect the photon transmission to the perovskite layer. Photoluminescent analysis for PEDOT:PSS and optimal MWCNTs significantly reduced light emission by 93.3% for 5% MWCNTs in PEDOT:PSS. The device with the optimized 5% MWCNTs/PEDOT:PSS hole collector achieved an efficiency of 18.09%, compared to 16.51% for pristine PEDOT:PSS. This work demonstrates a promising approach for enhancing the efficiency of inverted planar perovskite-based devices through the use of MWCNTs prepared at low temperatures using a simple solution process.

“…One of the effective methods to address this issue is to replace organic HEL by inorganic one with air stability and high conductivity. Some inorganic HELs have been used to fabricate the perovskite solar cells, such as CuI, 14,15 VO x , 16 CuSCN, 17,18 NiO x , 19‐21 and Cu 2 ZnSnS 4 22 …”

In this work, we construct a double inorganic hole extraction layer (HEL) of Cs:NiO x /CuInS 2 by inserting a thin film of Cs:NiO x between the perovskite (FAPbI 3 ) 1-x (MAPbBr 3 ) x and CuInS 2 layers and fabricate n-i-p type perovskite solar cells (PSCs) using Cs:NiO x /CuInS 2 as HEL. The efficiency of the PSCs with Cs:NiO x /CuInS 2 reaches 18.04% from 16.13% for the devices with single HEL of CuInS 2 , which is close to the highest efficiency (19.24%) of the devices with double inorganic HEL reported. In addition, the operational stability of the devices with Cs:NiO x /CuInS 2 is enhanced. The solar cells based on double HEL of Cs:NiO x /CuInS 2 maintains 95% of the original PCE after keeping 32 days in ambient air, while the devices based on single HEL of CuInS 2 keeps only 84% of the original PCE. In addition, the thermal stability of the PSCs with Cs:NiO x /CuInS 2 is also enhanced compared with the devices based on CuInS 2 . The results demonstrate that the application of double HEL of Cs: NiO x /CuInS 2 can enhance the performance and stability of PSCs simultaneously.
