A Comparative Study of Recombination Mechanisms and Long‐Term Outdoor Degradation in Perovskite Solar Cells and Modules Including Self‐Assembled Monolayers

open access: yesSolar RRL, Volume 9, Issue 13, July 2025.
This study compares inverted perovskite solar cells with and without a Me‐PACz self‐assembled monolayer (SAM) on NiOx. SAM integration improves energy level alignment between perovskite and NiOx, enhancing open‐circuit voltage . Temperature‐dependent DC and AC characterization reveals that SAM incorporation reduces interfacial recombination.

Accuracy of daily extreme air temperatures under natural variations in thermometer screen ventilation

open access: yesAtmospheric Science Letters, Volume 25, Issue 10, October 2024.
Naturally ventilated thermometers in Stevenson screens or similar shelters provide the mainstay of surface air temperature data. These work well, except, occasionally, at low wind speeds. This can affect the daily minimum and, rarely, maximum temperatures, which are important in meteorology and climatology.
