DOI: 10.1007/s10838-017-9392-x
Abstract: Did Goethe devise an empirically viable theory of classical ray optics? Or can we at least make use of his ideas to propose one? And if so, does this confront us with an intriguing case… read more here.

DOI: 10.1364/oe.448545
Abstract: We investigate gentle front side textures for perovskite/silicon tandem solar cells. These textures enhance the absorption of sunlight, yet are sufficiently gentle to allow deposition of an efficient perovskite top cell. We present a tandem… read more here.
