Assessing Suburban Air Quality Constraints on Free Cooling in an Irish City [PDF]

arXiv
Temperate climates are expected to have an expansion of the number of hours where ventilative cooling is needed and where potential is available even under climate change scenarios. Further to this, the use of free cooling in the form of untreated outdoor air has the potential to be a renewable energy source that adds flexibility to national ...

Discerning Blend Microstructure and Charge Recombination for Stable Biorenewable‐Based Organic Photovoltaics

Advanced Energy Materials, EarlyView.
A combination of morphological, electrical, and spectroscopy techniques is used to evaluate the degradation mechanisms of non‐fullerene (NFA)‐based organic photovoltaics (OPVs). Blends based on Y12 are more stable than Y6, aspeciallyOPVs from FO6‐T:Y12 demonstrated superior stability with an extrapolated T80 of over 2000 hours under maximum power point
