Renewable Energy vs Biodiversity: a major report!

— Renewable Energy vs Biodiversity: a major report following one year of intense work of various Swiss Institutions and PV-lab. Check the reviewed report here and the executive summary below. A lot of fruitful exchanges between two communities that follow similar targets (a healthier, bio-diverse and temperature-controlled work) but have sometimes challenges in understanding each other. Thanks to Sascha Nick for coordinating and dynamising the extended work brillantly!

Paper alert – Linking Nanoscopic Insights to Millimetric-Devices!

— Happy to share our new article 'Linking Nanoscopic Insights to Millimetric-Devices in Formamidinium-Rich Perovskite Photovoltaics', published in Advanced Materials.  In this review, the phase instabilities in state-of-the-art formamidinium (FA)-rich perovskite absorbers are discussed. Challenges in the field are assessed and future research directions are proposed for improving the operational lifetimes of perovskite devices. These approaches, which bridge nanoscale structural properties to working solar cell devices, are believed to be critical to assessing the realization of a bankable PSC product.' Link to article
