Perovskite-based tandem solar cells are promising candidates for industrial applications. This study demonstrated perovskite/silicon devices based on a conventional Si homojunction device configuration employing tunnel oxide passivating contact to improve the voltage. Moreover, we fabricated it without deposition of recombination layer large area while showing possibility applying industry mark...

In this "nano idea" paper, three concepts for the preparation of methylammonium lead halide perovskite particles are proposed, discussed, and tested. The first idea is based on the wet chemistry preparation of the perovskite particles, through the addition of the perovskite precursor solution to an anti-solvent to facilitate the precipitation of the perovskite particles in the solution. The sec...

Perovskite Oxide-Based Electrocatalysts In article number 2101605, Shi Chen, Shuangpeng Wang, Guichuan Xing, Hui Pan, and co-workers systematically summarize perovskite oxides as electrocatalysts for efficient oxygen evolution reaction (OER). The catalytic mechanism descriptors are also discussed in detail. Additionally, various strategies to improve the OER performance of carefully reviewed, i...

The work focused on the layered perovskite-related materials as potential electrolytic components of such devices proton conducting solid oxide fuel cells for area clean energy. two-layered perovskite BaLa2In2O7 with Ruddlesden–Popper structure was investigated a protonic conductor first time. role increasing amount blocks in ionic transport investigated. It shown that perovskites BaLanInnO3n+1...

Uniform Artificial Synapses In article number 2000196, Kai-Chiang Wu, Hao-Wu Lin, and co-workers demonstrate vacuum deposited halide perovskite devices that exhibit very uniform electrical synaptic characteristics. Utilizing these in the reservoir computing can simultaneously reduce circuitry complexity increase its recognition accuracy with noisy inputs. The findings promise to facilitate util...

Tin-Oxide Perovskites In article number 2200964, Non Thongprong, Thidarat Supasai, Nopporn Rujisamphan, and co-workers presented the pseudohalide salt of sodium tetrafluoroborate, whose anions have a higher electronegativity than other halide salts, with potential to passivate surface tin oxide while enhancing optoelectronic properties perovskite film. The current study presents facile effectiv...

In this review paper, recent progress in the fabrication, transfer, and fundamental physical properties of freestanding oxide perovskite thin films is discussed. First, main strategies for synthesis transfer are analyzed. initial section, particular attention devoted to use water-soluble (Ca,Sr,Ba)3Al2O6 as sacrificial layers, one most promising techniques fabrication membranes. The functionali...
