Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

Progress in Photovoltaics: Research and Applications, EarlyView.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.

Bionisch inspirierte Strahlungskühlung: Kühlen wie die Silberameise

Physik in unserer Zeit, EarlyView.
Wie kann ein wenige Millimeter großes Insekt helfen, Gebäude ohne Strom zu kühlen? Die Silberameise überlebt extreme Hitze mithilfe raffinierter Mikrostrukturen, die einen Großteil des Sonnenlichts zurückwerfen und gleichzeitig thermische Energie über Infrarotstrahlung in den Weltraum abführen.
