Exceptional advances in the control of material properties has been achieved, through careful manipulation of geometry on nano- and sub-nanometre length scales, in magnetoelectronics and nanomagnetism.1 Advanced techniques now allow for the creation of structures patterned on sub-micron length scales in three dimensions. New phenomena has been discovered in patterned magnets that can be strongly controlled by ion bombardment, multilayering, and lithographic patterning.Lire la suite
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.
