“…We anticipate this synchronous strategy will contribute to the rational control of surface defects via multiple interaction of NaDDTC for achieving both low defect density and stable inorganic perovskite, which would significantly improve performance when applied to future high-performance analogous perovskite optoelectronics or other electronics technologies.

commercialization due to ever-increasing power conversion efficiency (PCE), which has soared to 25.7% as of 2022. [1][2][3][4] Nonetheless, the inadequate stability caused by thermal degradation of hybrid perovskite still poses a great challenge for commercialization. [5] To circumvent this concern, all-inorganic cesium lead halide perovskites (CsPbX 3 , X = Br, I), whose volatile and vulnerable organic parts can be replaced by stable inorganic Cs + , have attracted considerable attention and exhibited great potential for both high-performance single-junction and top cells in tandem soar cells due to their unparalleled stability at high temperature. [6][7][8] In recent years, thanks to a lot of research work and incisive investigation, cesium-based inorganic perovskites have made remarkable progress in reducing the defect densities and stabilizing the black phase in the perovskite films, due especially to precursor solution optimization, [9][10][11][12] compositional engineering, [13][14][15] interface modification [16][17][18][19] and strain engineering. [6,20] Despite these unremitting efforts, the current record PCE is considerably lower than that of its hybrid counterpart and the Shockley-Queisser (S-Q) limit (≈30%). [21] This shortcoming is ascribed to a large energy loss (E loss ), suggesting that severe Shockley-Read-Hall recombination occurs in the interface or absorber layer in these solar cells, which is mainly attributed to the inevitable formation of a large number of shallow-or deeplevel defects in the crystal growth of CsPbI 3−x Br x film. [21][22][23] These undesirable defects, especially deep-level defects, are considered as nonradiative recombination centers and active sites for water adsorption. As a result, they tend to cause inferior device performance and long-term instability. [24] Thus, it is of great significance to prepare superior perovskite films with low-defect density for obtaining high-efficiency solar cells.Recently, intensive research on the deep-level physical mechanism of inorganic perovskite has led to improvements of the efficiency and stability of inorganic perovskite devices. [25][26][27][28] Lou et al. demonstrated the there are many point defects in inorganic perovskite, such as the Cs + vacancy (V Cs ) and undercoordinated Pb 2+ , etc. These inevitable defects can impair the interaction between Cs + and [PbI 6 ] 4− octahedra to some extent, thus reducing the energy difference between the black phase and yellow phase. [24,25] According to density functional theoryThe nonradiative charge recombination caused by surface defects and inferior crystalline quality are major roadblocks to further enhancing the performance of CsPbI 3−x Br x perovskite solar cells (PSCs). Theoretical calculations indicate that sodium diethyldithiocarbamate (NaDDTC), a popular bacteriostatic benign material, can initiate multiple interactions with the CsPbI 3−x Br x perovskite surface to effectively passivate the defects. The experimental results reveal that the NaDDTC can indeed passivate the elect...

“…Nowadays, a chief challenge related to MSCs is to reduce the feature size, including the microelectrode length, width, and gap between adjacent microelectrodes, which would greatly influence the integration level, reaction kinetics, areal operating voltage, and energy density. Thereby, many reported studies focused on the high-precision microfabrication techniques, such as photolithography [27], laser scribing technique [28][29][30], focused ion beam (FIB) etching [18,21,31], and printing methods [32][33][34]. Besides, considerable attention has been paid to improving electrochemical performance, which was usually sacrificed with the reduction in the size of MSCs [33,35], resulting from poor compatibility between electrode materials and multistep complex microfabrication process, such as temperature change or inevitable chemical corrosion and residue.…”

Ultracompact and customizable micro-supercapacitors (MSCs) are highly demanded for powering microscale electronics of 5G and Internet of Things technologies. So far, tremendous efforts have been concentrated on fabricating high-performance MSCs; however, compatible fabrication and monolithic integration of MSCs with microelectronic systems still remains a huge challenge taking into full consideration the factors such as electrode film fabrication, high-resolution microelectrode pattern, and electrolyte precise deposition. In this review, we summarize the recent advances of ultrasmall and integrated MSCs with tunable performance and customizable function, including key microfabrication technologies for patterning microelectrodes with superior resolution, precise deposition of customized electrolytes in an extremely small space, and feasible strategies for improving electrochemical performance by constructing thick microelectrodes and special electrode structure. Finally, the related challenges and key prospects of ultracompact and customizable MSCs, including compatible microfabrication methods for electrode materials and films, patterning microelectrodes, customizing shape-conformable electrolytes, performance optimization, and efficient integration with microelectronic systems, are put forward for further promoting their practical application.

Currently, one of the world's concerns, including Brazil, is to obtain answers to reduce energy dependence on fossil fuels. Environmental damage and possible scarcity of fossil fuels highlight the generation of clean energy to reduce environmental degradation. In the present article, it is proposed a model to analyze the economic and environmental feasibility of implementing solar photovoltaic systems in an industry. A case study in Brazil was used to test the model. The selected industrial sector chosen for the installation of the photovoltaic system was the parking lot with an estimated area of 187,653 m 2 . Regarding economic viability, the calculated net present value was $44,730,630.26, the internal rate of return was 14.52% per year, and the payback time was 132 months. The environmental impacts avoided in the use of the photovoltaic solar energy system were analyzed and the amount of carbon dioxide avoided in the atmosphere per kWh generated with the use of this clean energy showed that 25,381 trees would be needed to fix the CO 2 that would be emitted into the atmosphere.
