Un dels límits fonamentals que afecta l'eficiència de conversió en cèl·lules fotovoltaiques és la distribució espectral de la radiació solar. D'una banda, només els fotons amb energia superior al gap ...
Hauke, Philipp Hans-Jürgen (Fecha de defensa: 2013-04-05)
Many outstanding problems in quantum physics, such as high-Tc superconductivity or quark confinement, are still - after decades of research - awaiting commonly accepted explanations. One reason is that ...
