Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and ...

In a conventional solar cell, the energy of an absorbed photon in excess of the band gap is rapidly lost as heat, and this is one of the main reasons that the theoretical efficiency is limited to ~33% ...

UNSW researchers have achieved a world record energy conversion efficiency of 13.2% for high-bandgap kesterite (CZTS) solar cells with a laboratory scale cell that had been enhanced with hydrogen.

There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too. While serving as a visiting ...
