Abstract Trace elements diffuse negligible distances through the pristine crystal lattice in minerals: this is a fundamental assumption when using them to decipher geological processes. For example, reliable use of mineral zircon (ZrSiO 4 ) as U-Th-Pb geochronometer and trace element monitor requires minimal radiogenic isotope mobility. Here, atom probe tomography, we document effects crystal–plastic deformation on atomic-scale elemental distributions revealing sub-micrometre-scale...
Here we report for the first time a monolithic perovskite–CIGS tandem (CIGS = Cu(In,Ga)Se2) solar cell on flexible conductive steel substrate with an efficiency of 18.1%, highest to date, representing important step toward perovskite-based photovoltaics.
Cd-Free CZTS solar cell with above 10% efficiency was achieved by an Al<sub>2</sub>O<sub>3</sub>passivation layer prepared ALD.
GaP/Si heterostructures were grown by metal-organic chemical vapor deposition in which the formation of all heterovalent nucleation-related defects (antiphase domains, stacking faults, and microtwins) fully simultaneously suppressed, as observed via transmission electron microscopy (TEM). This was achieved through a combination intentional Si(100) substrate misorientation, Si homoepitaxy prior to GaP growth, nucleation Ga-initiated atomic layer epitaxy. Unintentional (311) surface faceting...
Abstract Lithium incorporation in kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) materials has been experimentally proven effective improving electronic quality for application photovoltaic devices. Herein, a feasible and solution‐based lithium post‐deposition treatment (PDT), enabling further efficiency improvement on the high‐performance baseline is reported dominant mechanism this proposed. In way, uniformly incorporated into grain interiors (GIs) without segregation at boundaries (GBs), which can...
Abstract High bandgap perovskite solar cells are integral to perovskite‐based multi‐junction tandem with efficiency potentials over 40%. However, at present, high devices underperform compared their mid counterparts in terms of voltage outputs and fill factors resulting lower than ideal efficiencies. Here, the low factor aspect is addressed by developing a cation‐diffusion‐based double‐sided interface passivation scheme that simultaneously provides bulk for 1.75 eV cell also compatible p‐i‐n...
An ultra-thin indium tin oxide interlayer design was developed for interfacing perovskite solar cells with Si thereby minimising shunting effects large area monolithic tandem devices.
Abstract Kesterite is an earth‐abundant energy material with high predicted power conversion efficiency, making it a sustainable and promising option for photovoltaics. However, large open circuit voltage V oc deficit due to non‐radiative recombination at intrinsic defects remains major hurdle, limiting device performance. Incorporating Ge into the kesterite structure emerges as effective approach enhancing performance by manipulating morphology. Herein, how different amounts of affect...
Boron nanosheets improve evaporation rates of hydrogel-based solar vapour generators. The extensive B–O bonds lead to high energy conversion efficiency and reduce water enthalpy. system also shows salt resistance durability.
Biominerals, such as nacreous bivalve shells, are important archives of environmental information. Most marine calcifiers form their shells from amorphous calcium carbonate, hypothesised to occur via particle attachment and stepwise crystallisation metastable precursor phases. However, the mechanism this transformation, including incorporation trace elements used for reconstructions, poorly constrained. Here, using Mediterranean mussel, we explore formation nacre meso- atomic scale. We use a...
High operating temperatures and sluggish kinetics are major obstacles for practical applications of MgH2 as a solid hydrogen carrier. Introducing nanoscaled high-activity catalysts has been effective in improving the cycling MgH2. However, it remains still unclear that between nanoparticle size morphology, which one is decisive factor catalytic activity given catalyst. In this work, we studied topic by taking nanostructured niobium oxide (Nb2O5) representative sample. Five types Nb2O5...
High thermal stability and sluggish absorption/desorption kinetics are still important limitations for using magnesium hydride (MgH2) as a solid-state hydrogen storage medium. One of the most effective solutions in improving properties MgH2 is to introduce suitable catalyst. Herein, novel nanoparticulate ZrNi with 10-60 nm size was successfully prepared by co-precipitation followed molten-salt reduction process. The 7 wt % nano-ZrNi-catalyzed composite desorbs 6.1 starting from ∼178 °C after...
