structure was found for the first time in a mineral composed by CaTiO 3 in 1839. Since then, multiple metal oxide perovskites (AMO 3 ) were developed, which have interesting properties for ferroelectric, superconductive, and pyroelectric applications. Metal halide perovskites (X is a halide anion such as Cl − , Br − , or I − ), which were developed later, display promising semiconducting properties. In particular, lead halide perovskites (APbX 3 ) are the most widely studied perovskite composition and are classified according to the A cation into hybrid perovskites (methylammonium bromide, MA or formamidinium, FA) and all-inorganic perovskites (cesium, Cs). [2] The electronic properties of the perovskites are related to the M-X bond, while the size of the A cation can introduce crystal distortion and change the symmetry of the ideal cubic crystal structure. [3] Interestingly, by using a large A organic cation, low-dimensional halide perovskites can be formed, including 2D sheets, 1D chains, or 0D clusters. [4] Lead halide perovskites are revolutionizing photovoltaic technology thank to their outstanding optical and electronic properties, low cost, and simple preparation. Compared to silicon-based technology, perovskites are prepared from more abundant and low-cost precursors. The superior performance and high efficiency of perovskite-based solar cells (PSC) are due to i) high optical absorption coefficient, ii) long carrier diffusion length This article delineates the state of the art for several materials used in the harvest, conversion, and storage of energy, and analyzes the challenges to be overcome in the decade ahead for them to reach the market and benefit society. The materials covered have had a special interest in recent years and include perovskites, materials for batteries and supercapacitors, graphene, and materials for hydrogen production and storage. Looking at the common challenges for these different systems, scientists in basic research should carefully consider commercial requirements when designing new materials. These include cost and ease of synthesis, abundance of precursors, recyclability of spent devices, toxicity, and stability. Improvements in these areas deserve more attention, as they can help bridge the gap for these technologies and facilitate the creation of partnerships between academia and industry. These improvements should be pursued in parallel with the design of novel compositions, nanostructures, and devices, which have led most interest during the past decade. Research groups are encouraged to adopt a cross-disciplinary mindset, which may allow more efficient use of existing knowledge and facilitate breakthrough innovation in both basic and applied research of energy-related materials.

Blue light emitting two dimensional (2D) and quasi-2D layered halide perovskites (LHPs) are gaining attention in solid-state lighting applications but their fragile stability in humid condition is one of the most pressing issues for their practical applications. Though water is much greener and cost effective, organic solvents must be used during synthesis as well as the device fabrication process for these LHPs due to their water-sensitivity/instability and consequently, water-stable blue-light emitting 2D and quasi-2D LHPs have not been documented yet. Here, water-mediated facile and cost-effective syntheses, characterizations, and optical properties of 16 organic-inorganic hybrid compounds are reported including 2D (A′) 2 PbX 4 (A′ = butylammonium, X = Cl/Br/I) (8 compounds), 3D perovskites (4), and quasi-2D (A′) p A x−1 B x X 3x+1 LHPs (A = methylammonium) (4) in water. Here, both composition and dimension of LHPs are tuned in water, which has never been explored yet. Furthermore, the dual emissive nature is observed in quasi-2D perovskites, where the intensity of two photoluminescence (PL) peaks are governed by 2D and 3D inorganic layers. The Pb(OH) 2 -coated 2D and quasi-2D perovskites are highly stable in water even after several months. In addition, single particle imaging is performed to correlate structural-optical property of these LHPs.

The exploration and optimization of numerous mixed perovskite compositions are causing a strong demand for high-throughput synthesis. Nevertheless high-throughput fabrication of perovskite films with representative film properties, which can efficiently screen the perovskite compositions for photovoltaic applications, has rarely been explored. A high-throughput inkjet printing approach that can automatically fabricate perovskite films with various compositions with high reproducibility and high speed is developed. The automatic sequential printing of four precursors forms 25 mixed films in a fast and reproducible manner. The obtained bandgaps, photoluminescence (PL) peak positions, and PL lifetimes allow for the efficient screening of perovskite compositions for photovoltaic applications. To exemplify this concept, among 25 tested films, two compositions CH 3 NH 3 PbBr 0.75 I 2.25 (MA) and (HC(NH 2 ) 2 ) 0.75 (CH 3 NH 3 ) 0.25 PbBr 0.75 I 2.25 (FA 0.75 MA 0.25 ) with a long (237 ns) and short (49.0 ns) PL lifetime, respectively, are screened out for device investigations. As expected, the MAbased device exhibits a much higher efficiency (19.0%) than that (15.3%) of the FA 0.75 MA 0.25 counterpart. This efficiency improvement is mainly ascribed to a smaller dark saturate current density, a lower level of energetic disorder, more efficient charge transfer and decreased charge recombination losses, which are consistent with the much longer PL lifetime in the database.
