The race to build the world’s most efficient solar cell is no longer a theoretical contest inside physics labs, it is a high‑stakes engineering sprint that will shape how quickly the global energy ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

Danish researchers have analyzed fundamental material properties of selenium solar cells and have found their potential is higher than generally believed. They used carrier-resolved photo-Hall ...

A research team in Italy has tested the performance of semitransparent wide-bandgap perovskite solar cells in underwater (UW) environments and has found that, at a 0.5–1 cm depth, the devices achieve ...

Solar energy is a crucial part of our clean energy future, but a new, highly efficient solar material has a hurdle that needs to be addressed. A recent study reveals how a microscopic weak spot can ...
