Australian researchers have increased photon absorption in a semiconductor to almost 99%, according to the University of Sydney. The absorber is a sub-wavelength thin-film semiconductor, and no complex nano-structures, meta-materials, exotic materials or difficult-to-create metal-non-metal combinations have been used. When light falls on a thin film etched with narrow grooves, light is directed sideways and …

A source of loss in Perovskite solar cells could disappear following the decoding of a mechanism that heals defects in the crystal lattice. Organic-inorganic metal halide perovskite solar materials are rapidly catching silicon in efficiency, and are showing promise as a mass produceable large scale technology. However, a lot of issues remain to be solved, …

James Webb Space Telescope assembly passed a critical step as NASA hoisted in the instrument package – the cameras and spectrographs that will record light from the huge golden mirror. So critical was this part of construction – the load is heavy, delicate, and had to be lowered into a confined box – that prior to …
