Concentrator photovoltaics achieves peak performance 3 décembre 2018

European project CPVMatch drives solar module efficiency up to 41.4 per cent.
In the development of photovoltaic technologies, Concentrator Photovoltaics (CPV) has so far achieved the highest efficiency for the conversion of sunlight into electricity. The basis for this latest achievement depends on special multi-junction solar cells as well as the ideal interplay between the cell and the module optics.

[Nanomaterials] – Research reveals exotic quantum states in double-layer graphene 26 juin 2019

Researchers from Brown and Columbia Universities have demonstrated previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensional nanomaterial. These new states, known as the fractional quantum Hall effect, arise from the complex interactions of electrons both within and across graphene layers.
