Understanding efficiency losses from radiative and nonradiative recombination in Cu₂ZnSn(S,Se)₄ solar cells

The photovoltaic performance of Cu2ZnSn(S,Se)4 solar cells has so far been hindered by open-circuit voltage losses. Here, the authors quantify such losses reported in the literature and point out the need to reduce non-radiative recombination for a breakthrough in power conversion efficiency.

Activatable second-near-infrared-window multimodal luminogens with aggregation-induced-emission and aggregation-caused-quenching properties for step-imaging guided tumor therapy

Traditional organic luminogens conventionally exhibit bright luminescence in the single state (e.g. solution or aggregated state), limiting their utility in heterogeneous environments. Here, the authors report aggregation-caused quenching / aggregation-induced emission dual property luminogens, that can balance radiative and non-radiative decay processes in both the solution and aggregation states.

A multipath error cancellation method based on antenna jitter

Jiyang Liu and colleagues present a signal processing method utilizing antenna jitter to cancel multipath errors introduced as satellite signals travel to a signal receiver. Their approach provides a low-cost solution for high-precision satellite positioning for Global Navigation Satellite System.
