Photon collection from quantum emitters is difficult, and their scale requires the use of free-space optical measurement setups which prevent packaging of quantum devices. Here, the authors design and fabricate a metasurface that acts as an immersion

While nanoscale emitters hold promise in single-photon devices, the directivity of their emission must be improved for practical applications. Here, Johlin et al. use an evolutionary algorithm to design a dielectric nanophotonic lens that greatly enh

Perovskite solar cells (PSCs) with a novel hybrid electrode structure, in which a single device can operate with either a vertical (sandwich) or lateral (back-contact) configuration of contacts, are demonstrated in this work. The hybrid structure was

Balancing the carrier selectivity and extraction by the selective contacts is of vital importance to the performance of the nanowire solar cells. Here Oener et al. employ a permanent local gate to overcome this tradeoff and substantially increase the

Nanostructured semiconductors feature resonant optical modes that confine light absorption in specific areas called “hot spots”. These areas can be used for localized extraction of the photogenerated charges, which in turn could drive chemical re

Abstract We propose two-focus fluorescence correlation spectroscopy (2fFCS) on basis of plasmonic nanoantennas that provide distinct hot spots that are individually addressable through polarization, yet lie within a single diffraction limited microsc

Solar water splitting using metal–insulator–semiconductor junctions has proven efficient, but these junctions degrade very rapidly. Here, the authors engineer metal–insulator–semiconductor interfaces in which Fermi-level pinning is reduced, p

Light-matter interactions with single quantum emitters are generally difficult to measure with both high-resolution and a large field of view. Here, Johlin et al. develop far-field super-resolution fluorescence methods to map near-field emitter-nanos

The luminescent solar concentrator (LSC) offers a potential pathway for achieving low-cost, fixed-tilt light concentration. Despite decades of research, conversion efficiency for LSC modules has fallen far short of that achievable by geometric concen
