Interlayer coupling, as a ubiquitous phenomenon residing amongst 2D supplies (2DMs) techniques, controls a skinny layer exfoliation process and the assembly of vdWHSs and behaves with a unique degree of freedom for engineering the properties of 2DMs. Interlayer coupling offers an opportunity to observe new physics and provides a novel strategy to modulate the digital and optoelectronic properties of materials for sensible device applications. We herein evaluation latest progress within the exploration of interlayer coupling in 2D semiconducting vdWHSs for potential applications in electronics and optoelectronics. Organic-inorganic metallic halide perovskite single-junction photo voltaic cells have attracted nice attention in the past few years because of a high document energy conversion efficiency (PCE) of 23.7{2a79250889bbb436aede83d3d9821727c714ae644fdce8eebb7ee5764bc860a0} and low-price fabrication processes. Beyond single-junction gadgets, low-temperature resolution processability, and bandgap tunability make the metal halide perovskites perfect candidates for fabricating tandem solar cells.

In this review, we’ll summarize recent analysis progress on the fabrication of extensive- (1.7 to 1.9 eV) and low-bandgap (1.1 to 1.3 eV) perovskite single-junction cells and their purposes in tandem cells. Key challenges and points in wide- and low-bandgap single-junction cells shall be discussed. We will survey present state-of-the-art perovskite tandem cells and discuss the constraints and challenges …
