“…One should refer to our previous reports for relevant experimental details. 27,28 For the semitransparent perovskite solar cell, the MoOx layer was thermally evaporated on the HTL layer in a vacuum chamber. Then the ITO was deposited by sputtering deposition at room temperature with a radiofrequency power of 70 W. Finally, the Ag metal grid was thermally evaporated on the ITO film.…”

“…The E CBM of KPAB-SnO 2 was increased by ~0.06 eV compared with that of the pristine SnO 2 , which facilitated an improved electron extraction and the high V oc of the corresponding PSCs. [50,51] High-quality perovskite films are indispensable for highperformance devices. To study the microstructure, the SEM images of perovskite films deposited on different ETLs were obtained, as shown in Figure 5 a and b.…”

Perovskite solar cells (PSCs) fabricated with a low-temperature (� 150 °C) SnO 2 -based electron transport layer (ETL) have been rapidly developing and demonstrate high power conversion efficiency (PCE). To further enhance the efficiency and stability of PSCs, high-quality perovskite and SnO 2 films are needed, and the interfacial performance between the SnO 2 ETL and the perovskite layer needs to be improved. In this work, potassium p-aminobenzoate (KPAB) was introduced to regulate the SnO 2 ETL to obtain reduced defects and an excellent wetting property, inducing vertically aligned crystal growth of the perovskites on the interface side of the SnO 2 ETL. In addition, the potassium ions were able to interact with the halogen ions of the perovskite, which further enhanced the quality of the perovskite film. Due to the abovementioned strengths of KPAB, we demonstrated that devices based on KPAB-SnO 2 have a higher power conversion efficiency (19.03 %), better reproducibility, and superior operational stability compared to devices with pristine SnO 2 .

“…Perovskite solar cells (PSCs) have attracted a lot of attention in recent years, owing to their excellent optical and electronic properties, such as large optical absorption coefficients, long carrier lifetimes, high carrier mobilities, and tunable bandgaps. [1,2] In addition, perovskite solar cells can be fabricated via various chemical routes as well, making them highly suitable for low-cost large-scale fabrication. [3,4] In the last 10 years, the power conversion efficiency (PCE) of PSCs has made significant progress, improving from 3.8% in 2009 to 25.7% in 2022, which shows that perovskite materials should be considered serious contenders for future solar cell applications that can compete with other the current popular photovoltaic materials.…”

The disordered distribution of defects in perovskite structures seriously disrupts the carrier transmission rates and limits the power conversion efficiency (PCE) in perovskite‐based solar cells. Defect passivation is an effective strategy to eliminate defects in perovskites and suppress the process of nonradiative recombination. Herein, 6‐aminonicotinic acid (6‐ANA, C6H6N2O2), which contains both amino and carboxyl groups, has been used, as a crosslinking agent, between perovskite grain boundaries, which allows for the development of efficient and stable perovskite solar cells (PSCs). The passivation mechanism of 6‐ANA that enables the fabrication of highly efficient and stable PSCs has systematically been investigated in this study. The results show that the crystallinity of the perovskite film improves with the addition of 6‐ANA in the perovskite films and the trap density is suppressed. The optimized efficiency achieved for the PSC device is as high as 19.71% while maintaining an initial efficiency of 75% after 500 h of shelf storage. This work provides a simple and effective strategy to reduce electronic defects, present in perovskite films, as well as at the interface between the perovskite films and the hole transport layers.
