Vacuum-free preparation of 7.5% efficient Cu2ZnSn(S,Se)4 solar cells based on metal salt precursors
TL;DR: A solution-based preparation route for 7.5% efficient thin-film solar cells with a kesterite-type Cu2ZnSn(S,Se)4 absorber is reported that allows low carbon residues after a rapid selenization step as discussed by the authors.
Journal ArticleDOI
Silicon lattice parameters as an absolute scale of length for high precision measurements of fundamental constants
D. Windisch,P. Becker +1 more
TL;DR: In this paper, a linear correlation between the absolute value of the lattice spacing and the oxygen concentration is observed, and the same lattice parameter is obtained for different silicon crystals to within a few parts in 10−8.
Journal ArticleDOI
Compositional dependence of the strain-free optical band gap in InxGa1−xN layers
Sara Pereira,Maria R. Correia,Teresa Monteiro,E. Pereira,Eduardo Alves,A.D. Sequeira,N. Franco +6 more
TL;DR: In this paper, the effect of strain on the compositional and optical properties of a set of epitaxial single layers of InxGa1−xN alloys was studied.
Journal ArticleDOI
Bimetallic PtAu Alloy Nanoparticles-Integrated g-C3N4 Hybrid as an Efficient Photocatalyst for Water-to-Hydrogen Conversion.
TL;DR: This study presents a robust, stable, and easily synthesizable PtAu/g-C3N4 hybrid material as a promising photocatalyst for H2 generation through water splitting.
