Progress in Photovoltaics: Research and Applications, EarlyView.Amorphous SnO2 films with low resistivity (~1.2 × 10−3 Ωcm) were realized by low‐temperature magnetron sputtering through control of O2 flow ratio, substrate temperature, and H incorporation. Si heterojunction solar cells incorporating these films achieved a conversion efficiency of 21.1%, approaching that of cells based on MS‐ITO and RPD‐SnO2 ...

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
Progress in Photovoltaics: Research and Applications, EarlyView.A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Small, EarlyView.A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2
Small, EarlyView.The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Small, EarlyView.The silver nanoparticle morphologies are identified thanks to ab initio models, including original families of defects and complex motifs, compared to measurements provided at targeted sizes (309, 561, 742, and 923 atoms). The crossings between structures to within a few atoms have been predicted due to very accurate computational conditions, which are

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis
Small, EarlyView.Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Small, EarlyView.This study introduces a room‐temperature process to fabricate patterned TiO2@TiC core–shell nanowires, merging the biocompatibility of TiO2‐NWs with the high conductivity of TiC. Through sputtering pressure and time modulation, the nanowires morphology and electrochemical properties are tuned, enabling enhanced capacitance, stability, and guided ...
