Thermal management of concentrator photovoltaics [PDF]

open access: yes
Photovoltaic Concentrator systems, which increase the solar radiation intensity on the photovoltaic cells, may reduce the system cost, if the cost of the concentrator is less than the photovoltaic material displaced.

Tetracyclic π‐Extended Multi‐Resonant TADF Emitters for Green PSF‐OLEDs With 37.7% EQE and BT.2020‐Compatible Top‐Emitting Devices

open access: yesAdvanced Functional Materials, EarlyView.
Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Solar Energetic Particle Charge States and Abundances with Nonthermal Electrons

open access: yesThe Astrophysical Journal
An important aspect of solar energetic particle (SEP) events is their source populations. Elemental abundance enhancements of impulsive SEP events, originating in presumed coronal reconnection episodes, can be fitted to steep power laws of A / Q , where ...
