“…Higher absorption intensity was observed for MAS-perovskite film as compared with CSM-perovskite film. Furthermore, the bandgap gathered is ~1.61 eV which still agrees with the tunable bandgap property of successfully formed perovskite materials 9,15 . In microwave-assisted synthesis, the perovskite can have regulated and controllable crystallization which can catalyze Ostwald ripening, promoting uniform nucleation of perovskites 16 .…”

“…All experiments and measurements for the triple cation perovskite (Cs0.1(MA0.17FA0.83)0.9Pb(I0.83Br0.17)3) were done in ambient environment (without the nitrogen-filled glovebox). The preparation of the CSM-perovskite solution followed the process in the recently published literature 8,9 . To perform the microwave-assisted synthesis, the perovskite solution was stirred before subjecting to Anton Paar Monowave 300 reactor (maximum power: 850 W, homogeneous heating at a rate of up to 9°C/sec).…”

Perovskite materials have drawn significant attention due to their distinct characteristics and increasing optoelectronic applications. The triple cation (Cs/MA/FA) perovskite precursor solution is commonly synthesized using the conventional perovskite stirring method (CSM) regulated within a nitrogen glovebox. However, the process requires a significant amount of time for preparation and limits the fabrication conditions in an ambient environment, hence impeding their potential for large-scale applications and ambient environment stability. Here, a triple cation perovskite (Cs0.1(MA0.17FA0.83)0.9Pb(Br0.17I0.83)3) precursor solution was prepared using the microwave-assisted synthesis (MAS) method and fabricated as a perovskite transistor in a "fully-ambient air" environment. The stability of perovskite films was evaluated by measuring their optical properties and comparing the characteristics of MAS-perovskite solution to the conventional stirring method (CSM). The perovskite films made via MAS exhibited an anomalous shift towards shorter wavelengths and an increase in linewidth as the temperature increased, highlighting the distinctive characteristics of the triple cation perovskite that was produced. These results were later analyzed and fitted to investigate the induced lattice thermal expansion, structural phase transition, and electron phonon interactions that highlighted the enhanced crystal quality from the MAS-perovskite films. Aside from the seven-fold PL enhancements, the fabrication of MAS-perovskite transistors in a completely ambient environment resulted in a ten-fold increase in electron carrier mobility compared to the CSM-perovskite devices indicating a large improvement in the crystalline formation mechanism of MAS-perovskite materials. The success in preparing the ambient-fabricated is beneficial for pushing the large-scale and efficient optoelectronic devices.

“…[5,6] In this regard, the exploitation and development of methods for manufacturing and scaling up PSCs has increased over time. [7][8][9][10][11][12][13][14][15][16][17][18] Although transparent conductive oxide (TCO) is normally utilized as substrates in the preparation of laboratory-scale cells, its utility in the fabrication of large-area modules for commercial applications is curtailed due to their rigidity and high weight. This has triggered the researchers to be in search for flexible polymer substrates such as PET and PEN.…”

Perovskite solar cell (PSC) technology experiences a remarkably rapid growth toward commercialization with certified efficiency of over 25%, along with the outstanding breakthrough in the development of SnO2. Owing to the wide bandgap, high electron mobility, chemical stability, and low photocatalytic activity, SnO2 has been the rising star to serve as electron transporting layer (ETL). More importantly, the low‐temperature fabrication process (<200 °C) enables SnO2 a promising candidate for the industry, making it compatible with the plastic substrates and large‐scale production, which is crucial for the flexible and scalable devices fabrication. In this review, the processing methods (solution‐based, vacuum‐based, and vapor‐based deposition) of low‐temperature SnO2 (LT‐SnO2) and the pros and cons of them with a focus on their scalability are discussed. Additionally, the morphologies of obtained LT‐SnO2 are investigated to guide the design and performance improvement of devices. The modification strategies to reduce undesired nonradiative recombination and passivate the defects in the bulk or at the interface of LT‐SnO2, influencing the quality of perovskite films, together with the efficiency and stability of cells are summarized. This review is a comprehensive overview of the studies on low‐temperature SnO2 ETL and provides detailed instructions for scalable PSCs.
