New Rice research projects get over $4 million funding to ‘transform’ future of advanced materials

Rice University materials scientist, Boris Yakobson, has won three awards from two federal agencies totaling $4,140,611 over several years to research challenging aspects of advanced materials’ production, performance and dynamics. A project titled “Mapping the synthetic routes for 2-dimensional materials” aims to unravel the molecular mechanisms that would enable the production of 2D materials for use in microchips and future electronics at industrial scale and quality.

Building on previous work on several iconic 2D materials such as graphene, molybdenum disulfide and hexagonal boron nitride, the Yakobson Research Group aims to establish a general approach to the development of predictive synthesis models for perovskites, nitrides, oxides and other materials coveted for energy and electronics applications.

Researchers develop a crystal capping layer to enable the formation of black-phase FAPbI3 perovskites in humid air

Researchers from Peking University, Tsinghua University, Beijing Institute of Technology and Ecole Polytechnique Fédérale de Lausanne (EPFL) have tackled a reproducibility challenge in black-phase formamidinium lead iodide (α-FAPbI3) perovskites. They explained that while this is the desired phase for photovoltaic applications, water can trigger formation of photoinactive impurity phases such as δ-FAPbI3. The team found that the classic solvent system for perovskite fabrication exacerbates this reproducibility issue. 

Growth of the photoactive black phase of formamidinium lead iodide (α-FAPbI3) usually requires dimethyl sulfoxide solvent, but the hygroscopic nature of this chemical also promotes water-induced degradation to the photoinactive phase. the scientists showed that a larger chlorinated organic molecule can form a hydrophobic capping layer that enables perovskite crystallization under humid conditions by protecting growing crystallites from water.

Researchers design efficient inverted perovskite solar cells using a synergistic bimolecular interlayer

A team of researchers, led by the Fudan University in China, has developed a p-i-n structure inverted perovskite solar cell that uses a synergistic bimolecular interlayer (SBI) and achieves what the team says is the smallest nonradiative recombination induced open-circuit voltage loss ever reported.

Researchers identify the potential of hexagonal perovskite oxides for next-gen protonic ceramic fuel cells

Researchers at Tokyo Institute of Technology and Tohoku University have reported hexagonal perovskite-related oxides with exceptionally high proton conductivity and thermal stability. 

The team explained that these materials' unique crystal structure and large number of oxygen vacancies enable full hydration and high proton diffusion, making them ideal candidates as electrolytes for next-generation protonic ceramic fuel cells that can operate at intermediate temperatures without degradation.

Researchers show how 2D perovskitoids enhance stability in perovskite solar cells

Researchers from Northwestern University, University of Toronto and KAUST have hypothesized that perovskitoids, with robust organic-inorganic networks enabled by edge- and face-sharing, could impede ion migration. This addresses the issue of the migration of cations between 2D and 3D layers which results in the disruption of octahedral networks that leads to degradation in performance over time

The scientists explored a set of perovskitoids of varying dimensionality, and found that cation migration within perovskitoid/perovskite heterostructures was suppressed compared to the 2D/3D perovskite case. Increasing the dimensionality of perovskitoids improves charge transport when they are interfaced with 3D perovskite surfaces – the result of enhanced octahedral connectivity and out-of-plane orientation.

Researchers develop efficient 2D Dion-Jacobson perovskite solar cell based on MXene contacts

Researchers at India's Chitkara University Institute of Engineering and Technology have developed 2D perovskite solar cells with MXene materials to build a PV device with remarkable efficiency and open-circuit voltage. The scientists claim the new cell architecture can help charge carriers move smoothly through the cell layers and reduce recombination losses.

The team's 2D DJ perovskite solar cell implemented bandgap grading techniques and use contacts based on a functionalized two-dimensional titanium carbide known as MXene. MXenes are compounds that take their name from their graphene-like morphology and are made via selective etching of certain atomic layers from a bulk crystal known as MAX. Recently, MXenes materials have shown promise for use in PV technology due to their unique optoelectronic properties, such as their large charge carrier mobility, excellent metallic conductivity, high optical transmittance, and tunable work function (WF).

Researchers improve the stability of perovskite solar cells with novel encapsulation method

Researchers at CHOSE (Centre for Hybrid and Organic Solar Energy, University of Rome Tor Vergata), BeDimensional, Istituto Italiano di Tecnologia and GreatCell Solar Italia recently addressed the stability issues presented by perovskite solar cells, by developing an industrial encapsulation process based on the lamination of highly viscoelastic semi-solid/highly viscous liquid adhesive atop perovskite solar cells and modules.

The encapsulant reportedly reduces the thermomechanical stresses at the encapsulant/rear electrode interface. The addition of thermally conductive two-dimensional hexagonal boron nitride into the polymeric matrix improves the barrier and thermal management properties of the encapsulant. Without any edge sealant, encapsulated devices withstood multifaceted accelerated ageing tests, retaining >80% of their initial efficiency.
