Abstract
Advanced characterisation plays an important role for further improvements of the cost effectiveness ($/Wp) of solar cells. This paper presents an overview of advanced characterisation techniques that are presently being used for the analysis of silicon wafer solar cells, either in the laboratory or in the [...]
Highlights
•Aberration-corrected TEM and EELS reveal structural and elemental profiles across GaAs/Si bond interfaces in wafer-bonded GaInP/GaAs/Si – multi-junction solar cells.
•Fluctuations in elemental concentration in nanometer-thick amorphous interface layers, including the disrubutions of light elements, are measured using EELS.
•The projected widths of the interface layers [...]

High quality large-area single crystal copper substrate is an effective method for preparing high-quality large-area single crystal graphene. There are several main methods for preparing single crystal copper: 1) Commercial single crystal copper is mostly produced by using the high-temperature hot casting mode continuous [...]

Metastable rocksalt phase in epitaxial GaN on sapphire
In a series of GaN epilayers grown by metalorganic chemical vapor deposition on sapphire, the GaN rocksalt structure has been detected by x-ray diffraction (XRD) and directly observed by high resolution transmission electron microscopy. The rocksalt GaN [...]
